So the story goes like this. The testSchemaDirs() function is
called with: a) the schema file, b) list of the directories that
contains XMLs documents that should be checked against the schema
file from a). However, the directories in the list are really
just their names and it's up to testSchemaDirs to construct the
absolute path and call testSchemaDir() which then does the actual
validation. The absolute path is constructed, but never actually
used (maybe due to a typo). Thus a VPATH build is broken.

When a SCSI controller is present, ESX adds several pciBridge devices
to vmx file. This fixes an error message where it refuses to create VM
due to not enough PCI devices available. This applies only to virtualHW
version >= 7.
Hand-entering indexes for 20 PCI controllers is not as tedious as
manually determining and entering their PCI addresses, but it's still
annoying, and the algorithm for determining the proper index is
incredibly simple (in all cases except one) - just pick the lowest
unused index.
The one exception is USB2 controllers because multiple controllers in
the same group have the same index. For these we look to see if 1) the
most recently added USB controller is also a USB2 controller, and 2)
the group *that* controller belongs to doesn't yet have a controller
of the exact model we're just now adding - if both are true, the new
controller gets the same index, but in all other cases we just assign
the lowest unused index.
With this patch in place and combined with the automatic PCI address
assignment, we can define a PCIe switch with several ports like this:
<controller type='pci' model='pcie-root-port'/>
<controller type='pci' model='pcie-switch-upstream-port'/>
<controller type='pci' model='pcie-switch-downstream-port'/>
<controller type='pci' model='pcie-switch-downstream-port'/>
<controller type='pci' model='pcie-switch-downstream-port'/>
<controller type='pci' model='pcie-switch-downstream-port'/>
<controller type='pci' model='pcie-switch-downstream-port'/>
...
These will each get a unique index, and PCI addresses that connect
them together appropriately with no pesky numbers required.

Extract whether a given drive has a tray and whether there is no image

Negative logic for the image insertion is chosen so that the flag is set
only if we are certain of the fact.
This is identical to type='bridge', but without the "connect to a
bridge" part, so it can be handled by using the same functions (and
often even the same cases in switch statements), after renaming
virLXCProcessSetupInterfaceBridged() to virLXCProcessInterfaceTap()
and enhancing it to skip bridge-related items when brname == NULL.
To be truly useful, we need to support setting the ip address on the

type='bridge'), as well as setting the peer address for both.
The <script> element (supported by type='ethernet' in qemu) isn't

This test requests a read-only virtual FAT drive on the IDE bus.
Read-only IDE drives are unsupported, but libvirt only displays
the error if it has the QEMU_CAPS_DRIVE_READONLY capability.
Read-write FAT drives are also unsupported.
Rather than only assigning a PCI address when no address is given at
all, also do it when the config says that the address type is 'pci',
but it gives no address (virDeviceInfoPCIAddressWanted()).
There are also several places after parsing but prior to address
assignment where code previously expected that any info with address
type='pci' would have a *valid* PCI address, which isn't always the
case - now we check not only for type='pci', but also for a valid
address (virDeviceInfoPCIAddressPresent()).
The test case added in this patch was directly copied from Cole's patch titled:

There is a lot to explain, but I try to make it as short as
possible. I'd start by pasting some parts of sys/stat.h:
extern int stat (const char *__restrict __file,
struct stat *__restrict __buf) __THROW __nonnull ((1, 2));
extern int __REDIRECT_NTH (stat, (const char *__restrict __file,
struct stat *__restrict __buf), stat64)
__nonnull ((1, 2));
__extern_inline int
__NTH (stat (const char *__path, struct stat *__statbuf))
{
return __xstat (_STAT_VER, __path, __statbuf);
}
Only one of these is effective at once, due to some usage of
the mess we are dealing with in here. So, basically, while
compiling or linking stat() in our code can be transformed into
some other func. Or a dragon.
Now, if you read stat(2) manpage, esp. "C library/kernel
differences" section, you'll learn that glibc uses some tricks
for older applications to work. I haven't gotten around actual
code that does this, but based on my observations, if 'stat'
symbol is found, glibc assumes it's dealing with ancient
application. Unfortunately, it can be just ours stat coming from
our mock. Therefore, calling stat() from a test will end up in
our mock. But since glibc is not exposing the symbol anymore, our
call of real_stat() will SIGSEGV immediately as the pointer to
function is NULL. Therefore, we should expose only those symbols
we know glibc has.

If they're available and we need to pass secrets to qemu, then use the
qemu domain secret object in order to pass the secrets for RBD volumes
instead of passing the base64 encoded secret on the command line.
The goal is to make AES secrets the default and have no user interaction
required in order to allow using the AES mechanism. If the mechanism
is not available, then fall back to the current plain mechanism using
a base64 encoded secret.
New APIs:
qemu_domain.c:
qemuDomainGetSecretAESAlias:
Generate/return the secret object alias for an AES Secret Info type.
This will be called from qemuDomainSecretAESSetup.
qemuDomainSecretAESSetup: (private)
This API handles the details of the generation of the AES secret
and saves the pieces that need to be passed to qemu in order for
the secret to be decrypted. The encrypted secret based upon the
domain master key, an initialization vector (16 byte random value),
and the stored secret. Finally, the requirement from qemu is the IV
and encrypted secret are to be base64 encoded.
qemu_command.c:
qemuBuildSecretInfoProps: (private)
Generate/return a JSON properties object for the AES secret to
be used by both the command building and eventually the hotplug
code in order to add the secret object. Code was designed so that
in the future perhaps hotplug could use it if it made sense.
qemuBuildObjectSecretCommandLine (private)
Generate and add to the command line the -object secret for the
secret. This will be required for the subsequent RBD reference
to the object.
qemuBuildDiskSecinfoCommandLine (private)
Handle adding the AES secret object.
Adjustments:
qemu_domain.c:
The qemuDomainSecretSetup was altered to call either the AES or Plain
Setup functions based upon whether AES secrets are possible (we have
the encryption API) or not, we have secrets, and of course if the
protocol source is RBD.
qemu_command.c:
Adjust the qemuBuildRBDSecinfoURI API's in order to generate the
specific command options for an AES secret, such as:
-object secret,id=$alias,keyid=$masterKey,data=$base64encodedencrypted,
format=base64
-drive file=rbd:pool/image:id=myname:auth_supported=cephx\;none:\
mon_host=mon1.example.org\:6321,password-secret=$alias,...
where the 'id=' value is the secret object alias generated by
concatenating the disk alias and "-aesKey0". The 'keyid= $masterKey'
is the master key shared with qemu, and the -drive syntax will
reference that alias as the 'password-secret'. For the -drive
syntax, the 'id=myname' is kept to define the username, while the
'key=$base64 encoded secret' is removed.
While according to the syntax described for qemu commit '60390a21'
or as seen in the email archive:
https://lists.gnu.org/archive/html/qemu-devel/2016-01/msg04083.html
it is possible to pass a plaintext password via a file, the qemu
commit 'ac1d8878' describes the more feature rich 'keyid=' option
based upon the shared masterKey.
Add tests for checking/comparing output.
NB: For hotplug, since the hotplug code doesn't add command line
arguments, passing the encoded secret directly to the monitor
will suffice.
Introduce virCryptoHaveCipher and virCryptoEncryptData to handle
performing encryption.
virCryptoHaveCipher:
Boolean function to determine whether the requested cipher algorithm
is available. It's expected this API will be called prior to
virCryptoEncryptdata. It will return true/false.
virCryptoEncryptData:
Based on the requested cipher type, call the specific encryption
API to encrypt the data.
Currently the only algorithm support is the AES 256 CBC encryption.
Adjust tests for the API's
Create a mock for virRandomBytes to generate a not so random value.
This should be usable by other tests that need a not so random number
to be generated by including the virrandommock at preload.
The "random number" generated is based upon the size of the expected
stream of bytes being returned where each byte in the result gets
the index of the array - hence a 4 byte array returns 0x00010203.
According to QEMU docs, the '-m' option for specifying RAM is by default
in MiB, and a suffix of "M" or "G" may be passed for values in MiB and
GiB respectively. This commit adds support and a test for the same.

All qemu versions we support have QEMU_CAPS_DEVICE, so checking
for it is redundant. Remove the usage.
The code diff isn't clear, but all that code is just inindented
with no other change.
Test cases that hit qemuDomainAssignAddresses but don't have
infrastructure for specifying qemuCaps values see lots of
churn, since now PCI addresses are in the XML output.
Upcoming patches are going to make the disk portion of these
test cases fail. In order to make it work, we would need to
extend the qemuargv2xml test infrastructure to handle qemuCaps.
This is worthwhile to do at some point but isn't critical.
Instead just drop the offending portion, which isn't even the
target of the test cases anyways
This wires up qemuDomainAssignAddresses into the new
virDomainDefAssignAddressesCallback, so it's always triggered
via virDomainDefPostParse. We are essentially doing this already
with open coded calls sprinkled about.
qemu argv parse output changes slightly since previously it wasn't
hitting qemuDomainAssignAddresses.

Instead of disabling auto-login of all scsi targets (even those
that do not "belong" to libvirt), use iscsiadm's "--op nonpersistent"
during discovery of iSCSI targets (e.g. "iscsiadm --mode discovery
--type sendtargets") in order to avoid the node database being altered
which led to the need for the "large hammer" approach taken by
commit id '3c12b654'.
This commit removes the virISCSITargetAutologin adjustment (eg. the setting
of node.startup to "manual"). The iscsiadm command has supported this mode
of operation as of commit id 'ad873767' to open-iscsi.
The only case where the hardware capabilities influence the result
is when no <gic/> element was provided.
The test programs now ensure both that the correct GIC version is
picked in that case, and that hardware capabilities are not taken
into account when the user has already picked a GIC version.
Now that we choose the GIC version based on hardware features when
no <gic/> element has been provided, we need a way to fake the GIC
capabilities of the host.
Update the qemuxml2argv and qemuxml2xml tests to allow this.

which we no longer support anyway.
Additionally, this solves the issue of some QEMU binaries being

For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.

There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline
function that calls __xstat(_STAT_VER, ...) or a macro that does
the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a

Some of the test configuration files in tests/xlconfigdata

features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.
Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures

libvirt may automatically add a pci-root or pcie-root controller to a
domain, depending on the arch/machinetype, and it hopefully always
makes the right decision about which to add (since in all cases these
controllers are an implicit part of the virtual machine).
But it's always possible that someone will create a config that
explicitly supplies the wrong type of PCI controller for the selected
machinetype. In the past that would lead to an error later when
libvirt was trying to assign addresses to other devices, for example:
XML error: PCI bus is not compatible with the device at
0000:00:02.0. Device requires a PCI Express slot, which is not
provided by bus 0000:00
(that's the error message that appears if you replace the pcie-root
controller in a Q35 domain with a pci-root controller).
This patch adds a check at the same place that the implicit
controllers are added (to ensure that the same logic is used to check
which type of pci root is correct). If a pci controller with index='0'
is already present, we verify that it is of the model that we would
have otherwise added automatically; if not, an error is logged:
The PCI controller with index='0' must be " model='pcie-root' for
this machine type, " but model='pci-root' was found instead.

to change media would attempt to re-eject the tray even if it wouldn't
be notified when the tray opened. Add a capability bit and skip retrying
for old qemus.
The man page says: "(Re)-Connect to the hypervisor. When the shell is
first started, this is automatically run with the URI parameter
requested by the "-c" option on the command line." However, if you run:
virsh -c 'test://default' 'connect; uri'
the output will not be 'test://default'. That's because the 'connect'
command does not care about any virsh-only related settings and if it is
run without parameters, it connects with @uri == NULL. Not only that
doesn't comply to what the man page describes, but it also doesn't make
sense. It also means you aren't able to reconnect to whatever you are
connected currently.
So let's fix that in both virsh and virt-admin add a test case for it.

Similarly to what commit 7140807917 did with some internal paths,
clear vnc socket paths that were generated by us. Having such path in
the definition can cause trouble when restoring the domain. The path is
generated to the per-domain directory that contains the domain ID.
However, that ID will be different upon restoration, so qemu won't be
able to create that socket because the directory will not be prepared.
To be able to migrate to older libvirt, skip formatting the socket path
in migratable XML if it was autogenerated. And mark it as autogenerated
if it already exists and we're parsing live XML.
Best viewed with '-C'.

Currently we only allow /dev/random and /dev/hwrng as host input
for <rng><backend model='random'/> device. This was added after
various upstream discussions in commit 4932ef45
However this restriction has generated quite a few complaints over
the years, so a new discussion was initiated:
http://www.redhat.com/archives/libvir-list/2016-April/msg00987.html
Several people suggested removing the restriction, and nobody really
spoke up to defend it. So this patch drops the path restriction
entirely

This unifies the test scripts to all use the similar pattern added for
schematests in ace4aecd. This gives the following
- Enables running all tests from outside of tests/ dir
- Drops redundant abs_* definitions, which are set by test-lib.sh
- Drops unnecessary srcdir variable which was only used for sourcing
test-lib.sh
Behavior changes:
- srcdir can no longer be overwritten, but I don't know why anyone would
really need to...
- Script VERBOSE setting no longer prints commands executed by test-lib.sh.
if anyone cares I suggest handling this in test-lib.sh which already
has other verbose style handling
These old tests expect to run against a real xen connection via
xend running on the host. Our intentions for the test suite are
that it doesn't require interacting with any specific host resources,
so these don't really belong here.
Store the test list in libvirtd_test_scripts, and use it where
appropriate. This also fixes the fact that we didn't ship

According to the dnsmasq manpage, the netmask for IPv4 address ranges
will be auto-deteremined from the interface dnsmasq is listening on,
but it can't do this for IPv6 for some reason - it instead assumes a
network prefix of 64 for all IPv6 address ranges. If this is
incorrect, dnsmasq will refuse to give out an address to clients,
instead logging this message:
dnsmasq-dhcp[2380]: no address range available for DHCPv6 request via virbr0
The solution is for libvirt to add ",$prefix" to all IPv6 dhcp-range
arguments when building the dnsmasq.conf file.

While working on the tests for the secret initialization vector, I found
that the existing iSCSI tests were lacking in how they defined the IQN.
Many had IQN's of just 'iqn.1992-01.com.example' for one disk while using
'iqn.1992-01.com.example/1' for the second disk (same for hostdevs - guess
how they were copied/generated).
Typically (and documented this way), IQN's would include be of the form
'iqn.1992-01.com.example:storage/1' indicating an IQN using "storage" for
naming authority specific string and "/1" for the iSCSI LUN.
So modify the input XML's to use the more proper format - this of course
has a ripple effect on the output XML and the args.
Also note that the "%3A" is generated by the virURIFormat/xmlSaveUri

virTypedParamsValidate currently uses an index based check to find
duplicate parameters. This check does not work. Consider the following
simple example:
We have only 2 keys
A (multiples allowed)
B (multiples NOT allowed)
We are given the following list of parameters to check:
A
A
B
If you work through the validation loop you will see that our last iteration
through the loop has i=2 and j=1. In this case, i > j and keys[j].value.i will
indicate that multiples are not allowed. Both conditionals are satisfied so
an incorrect error will be given: "parameter '%s' occurs multiple times"
This patch replaces the index based check with code that remembers
the name of the last parameter seen and only triggers the error case if
the current parameter name equals the last one. This works because the
list is sorted and duplicate parameters will be grouped together.
In reality, we hit this bug while using selective block migration to migrate

This is backed by the qemu device pxb-pcie, which will be available in
qemu 2.6.0.
As with pci-expander-bus (which uses qemu's pxb device), the busNr
attribute and <node> subelement of <target> are used to set the bus_nr
and numa_node options.
During post-parse we validate that the domain's machinetype is
q35-based (since the device shows up for 440fx-based machinetypes, but
is unusable), as well as checking that <node> specifies a node that is
actually configured on the guest.
This controller provides a single PCIe port on a new root. It is
similar to pci-expander-bus, intended to provide a bus that can be
associated with a guest-identifiable NUMA node, but is for
machinetypes with PCIe rather than PCI (e.g. q35-based machinetypes).
Aside from PCIe vs. PCI, the other main difference is that a
pci-expander-bus has a companion pci-bridge that is automatically
attached along with it, but pcie-expander-bus has only a single port,
and that port will only connect to a pcie-root-port, or to a
pcie-switch-upstream-port. In order for the bus to be of any use in
the guest, it must have either a pcie-root-port or a
pcie-switch-upstream-port attached (and one or more
pcie-switch-downstream-ports attached to the
pcie-switch-upstream-port).
The pxb device is a PCIe expander bus that can be added to any
Q35-based machinetype. A single PCIe port (*not* hotpluggable) is
provided; if more than one device is desired, or if hotplug
support is needed, either a pcie-root-port, or some combination of
pcie-switch-upstream-port and pcie-swith-downstream-ports must be
added to it. It can have a NUMA node number associated with it, as
well as a bus number.
This is backed by the qemu device "pxb".
The pxb device always includes a pci-bridge that is at the bus number
of the pxb + 1.
busNr and <node> from the <target> subelement are used to set the
bus_nr and numa_node options for pxb.
During post-parse we validate that the domain's machinetype is
440fx-based (since the pxb device only works on 440fx-based machines),
and <node> also gets a sanity check to assure that the NUMA node
specified for the pxb (if any - it's optional) actually exists on the
guest.
This is a standard PCI root bus (not a bridge) that can be added to a
440fx-based domain. Although it uses a PCI slot, this is *not* how it
is connected into the PCI bus hierarchy, but is only used for
control. Each pci-expander-bus provides 32 slots (0-31) that can
accept hotplug of standard PCI devices.
The usefulness of pci-expander-bus relative to a pci-bridge is that
the NUMA node of the bus can be specified with the <node> subelement
of <target>. This gives guest-side visibility to the NUMA node of
attached devices (presuming that management apps only assign a device
to a bus that has a NUMA node number matching the node number of the
device on the host).
Each pci-expander-bus also has a "busNr" attribute. The expander-bus
itself will take the busNr specified, and all buses that are connected
to this bus (including the pci-bridge that is automatically added to
any expander bus of model "pxb" (see the next commit)) will use
busNr+1, busNr+2, etc, and the pci-root (or the expander-bus with next
lower busNr) will use bus numbers lower than busNr.
The pxb device is a PCI expander bus that can be added to any
440fx-based machinetype. The PCI bus that is created has 32 standard
PCI slots (hotpluggable). It can have a NUMA node number associated
with it, as well as a bus number.
When support for dmi-to-pci-bridge was added, it was assumed that,
just as with the pci-root bus, slot 0 was reserved. This is not the
case - it can be used to connect a device just like any other slot, so
remove the restriction and update the test cases that auto-assign an
address on a dmi-to-pci-bridge.
* Add a test for listen=XXX and <listen address=YYY/> collision error
* Add an explicit test for listen=XXX duplicated to <listen address=XXX/>
We implicitly test it elsewhere but I figure it's better to be explicit,
and this test case can be extended in the future for additional listen
back compat if/when we support <listen type='socket'/> syntax

If the -object secret capability exists, then get the path to the
masterKey file and provide that to qemu. Checking for the existence
of the file before passing to qemu could be done, but causes issues
in mock test environment.
Since the qemuDomainObjPrivate is not available when building the
command line, the qemuBuildHasMasterKey API will have to suffice
as the primary arbiter for whether the capability exists in order
to find/return the path to the master key for usage.
Created the qemuDomainGetMasterKeyAlias API which will be used by
later patches to define the 'keyid' (eg, masterKey) to be used by
other secrets to provide the id to qemu for the master key.
Add a capability bit for the qemu secret object.
Adjust the 2.6.0-1 caps/replies to add the secret object. For the

Commit d77ffb6876 added not only reporting of the PCI header type, but
also parsing of that information. However, because there was no parsing
done for the other sub-PCI capabilities, if there was any other
capability then a valid header type name (like phys_function or
virt_functions) the parsing would fail. This prevented passing node
device XMLs that we generated into our own functions when dealing with,
e.g. with SRIOV cards.
Instead of reworking the whole parsing, just fix this one occurence and
remove a test for it for the time being. Future patches will deal with

Problem is that in the test any status file matching

different. This is then producing an unexpected results.
Instead of defining an order in which the files are loaded, make

that the code doing the parsing is used in real NSS module where

the *NetOrder take the address in network order, the other functions in

If a <graphics type='spice'> has no port nor tlsPort set, the generated
QEMU command line will contain -spice port=0.
This is later going to be ignored by spice-server, but it's better not

As an empty -spice is not allowed, we still need to append port=0 if we

Even if nss is disabled, the build system tries to build some

If we expose this information, which is one byte in every PCI config

The only purpose of this test is to catch possible linking
problems with libnss_libvirt.so.2.
One of the problems I faced was that the NSS plugin was unloaded
immediately after it got loaded and the name resolution process
continued with next configured option. Without any error. It was
very hard to debug why until I created this simple test and found
out immediately that there were some symbols missing. The reason
why problem was not caught in nsstest is that in the test we want
to use all the fancy stuff and therefore link it with libvirt.la.
So even if there's a symbol missing in the NSS plugin it will be
found in the libvirt.la.
But even after I resolved the issue we still need this test
because files the NSS plugin is built from are still live (mostly
those under utils/ dir). So as they change new symbol might be
required which would render the NSS plugin unusable.

None of the existing domXML configs under tests/* specify a
default cache mode since default generally means "use the
hypervisor default" and is left unset by the various hypervisor
drivers. Add a config to tests/domainschemadata that specifies
cache='default'.
Currently we spawn couple of binaries in our test suite.
Moreover, we provide some spoofed versions of system binaries
hoping that those will be executed instead of the system ones.
For instance, for testing SSH socket we have written our own ssh
binary for producing predictable results. We certainly don't want
to execute the system ssh binary.
However, in order to prefer our binaries over system ones, we
need to set PATH environment variable. But this is done only at
the Makefile level. So if anybody runs a test by hand that
expects our spoofed binary, the test ends up executing real
system binaries. This is not good. In fact, it's terribly wrong.
The fix lies in a small trick - putting our build directory at
the beginning of the PATH environment variable in each test.
Hopefully, since every test has this VIRT_TEST_MAIN* wrapper, we
can fix this at a single place.
Moreover, while this removes setting PATH for our tests written
in bash, it's safe as we are not calling anything ours that would
require PATH change there.

The 'actualCount' variable, formerly just 'count', is only used
internally by the macro, so it's better to move its declaration
inside the macro as well: this way, it doesn't have to be declared
by every single user.
The new name is less generic to make clashes less likely.
When checking the number of devices added to a device list, use the
nhostdevs variable instead of its value, so that the test can keep
working even if more hostdevs are added.
This attribute is used to extend secondary PCI bar and expose it to the
guest as 64bit memory. It works like this: attribute vram is there to
set size of secondary PCI bar and guest sees it as 32bit memory,
attribute vram64 can extend this secondary PCI bar. If both attributes
are used, guest sees two memory bars, both address the same memory, with
the difference that the 32bit bar can address only the first part of the
whole memory.

When there isn't a ssh -X type session running and a user has not
been added to the libvirt group, attempts to run 'virsh -c qemu:///system'
commands from an otherwise unprivileged user will fail with rather
generic or opaque error message:
"error: authentication failed: no agent is available to authenticate"
This patch will adjust the error code and message to help reflect the
situation that the problem is the requested mechanism is UNAVAILABLE and
a slightly more descriptive error. The result on a failure then becomes:
"error: authentication unavailable: no polkit agent available to
authenticate action 'org.libvirt.unix.manage'"
A bit more history on this - at one time a failure generated the
following type message when running the 'pkcheck' as a subprocess:
"error: authentication failed: polkit\56retains_authorization_after_challenge=1
Authorization requires authentication but no agent is available."
but, a patch was generated to adjust the error message to help provide
more details about what failed. This was pushed as commit id '96a108c99'.
That patch prepended a "polkit: " to the output. It really didn't solve
the problem, but gave a hint.
After some time it was deemed using DBus API calls directly was a
better way to go (since pkcheck calls them anyway). So, commit id
'1b854c76' (more or less) copied the code from remoteDispatchAuthPolkit
and adjusted it. Then commit id 'c7542573' adjusted the remote.c
code to call the new API (virPolkitCheckAuth). Finally, commit id
'308c0c5a' altered the code to call DBus APIs directly. In doing
so, it reverted the failing error message to the generic message
that would have been received from DBus anyway.

Per-domain directories were introduced in order to be able to
completely separate security labels for each domain (commit
f1f68ca334). However when the domain
name is long (let's say a ridiculous 110 characters), we cannot
connect to the monitor socket because on length of UNIX socket address
is limited. In order to get around this, let's shorten it in similar
fashion and in order to avoid conflicts, throw in an ID there as well.
Also save that into the status XML and load the old status XMLs
properly (to clean up after older domains). That way we can change it
in the future.
The shortening can be seen in qemuxml2argv tests, for example in the
hugepages-pages2 case.

The target= setting in xl disk configuration can be used to encode
meta info that is meaningful to a backend. Leverage this fact to
support qdisk network disk types such as rbd. E.g. <disk> config
such as
<disk type='network' device='disk'>
<driver name='qemu' type='raw'/>
<source protocol='rbd' name='pool/image'>
<host name='mon1.example.org' port='6321'/>
<host name='mon2.example.org' port='6322'/>
<host name='mon3.example.org' port='6322'/>
</source>
<target dev='hdb' bus='ide'/>
<address type='drive' controller='0' bus='0' target='0' unit='1'/>
</disk>
can be converted to the following xl config (and vice versa)
disk = [ "format=raw,vdev=hdb,access=rw,backendtype=qdisk,
target=rbd:pool/image:auth_supported=none:mon_host=mon1.example.org\\:6321\\;mon2.example.org\\:6322\\;mon3.example.org\\:6322"
]
Note that in xl disk config, a literal backslash in target= must
be escaped with a backslash. Conversion of <auth> config is not
handled in this patch, but can be done in a follow-up patch.
Also add a test for the conversions.

The most formal form of xl disk configuration uses key=value
syntax to define each configuration item, e.g.
format=raw, vdev=xvda, access=rw, backendtype=phy, target=disksrc
Change the xl disk formatter to produce this syntax, which allows
target= to contain meta info needed to setup a network-based
disksrc (e.g. rbd, nbd, iscsi). For details on xl disk config
format, see $xen-src/docs/misc/xl-disk-configuration.txt
Update the disk config in the tests to use the formal syntax.
But add tests to ensure disks specified with the positional
parameter syntax are correctly converted to <disk> XML.

PostParse handles it for us now.
This causes some test suite churn; qemu's custom PostParse could is
now invoked before the generic AddImplicitControllers, so PCI
controllers end up sequentially in the XML before the generically
added IDE controllers. So it's just some XML reordering
Seems like the natural fit, since we are already adding other XML bits
in the PostParse routine.
Previously AddImplicitControllers was only called at the end of XML
parsing, meaning code that builds a DomainDef by hand had to manually
call it. Now those PostParse callers get it for free.
There's some test churn here; xen xm and sexpr test suite bits weren't
calling this before, but now they are, so you'll see new IDE controllers.
I don't think this will cause problems in practice, since the code already
needs to handle these implicit controllers like in the case when a user
defines their own XML.
Since commit 51045df01b, the QEMU_CAPS_DEVICE capability is enabled
automatically and shouldn't be passed as an argument to DO_TEST();
however, commit 998a936c4c accidentally introduced few such uses.
This was only used for test 'xml blanking', which has now all
been removed, and isn't an ideal paradigm anyways since it
inhibits easy XML regeneration.
The memory XML blanking is only there to avoid the unit= churn that
was added by default a long time ago.
Drop the blanking, switch over to using the standard comparison
helpers, and regenerate the output with VIR_TEST_REGENERATE_OUTPUT.
If a qemuargv has iscsi or ceph secrets on the command line, we will
convert that to XML like:
<auth username='myname'>
<secret type='iscsi'/>
</auth>
This is not valid XML, as either a UUID or usage must be specified in
the secret block. It's not clear though how the argv2xml code can do
anything correct here, since XML like this requires a libvirt secret
object to have already been defined.
The current test suite handles this by blanking out any <secret> block
in the XML. This avoids domainschematest failures.
Instead of blanking, let's hardcode a usage= name. This lets us test
the other bits of generated <secret> XML, and is a step towards wiring
up VIR_TEST_REGENERATE_OUTPUT
Since the daemon can manage and add (at fresh start) multiple servers,

The method will now return 0 on success and -1 on error, rather than number of
items which it iterated over before it returned back to the caller. Since the
only place where we actually check the number of elements iterated is in
virhashtest, return value of 0 and -1 can be a pretty accurate hint that it
iterated over all the items. However, if we really want to know the number of
items iterated over (like virhashtest does), a counter has to be provided
through opaque data to each iterator call. This patch adjusts return value of
virHashForEach, refactors the body, so it returns as soon as one of the
iterators fail and adjusts virhashtest to reflect these changes.
Signed-off-by: Erik Skultety <eskultet@redhat.com>
Our existing virHashForEach method iterates through all items disregarding the
fact, that some of the iterators might have actually failed. Errors are usually
dispatched through an error element in opaque data which then causes the
original caller of virHashForEach to return -1. In that case, virHashForEach
could return as soon as one of the iterators fail. This patch changes the
iterator return type and adjusts all of its instances accordingly, so the
actual refactor of virHashForEach method can be dealt with later.

Test all kinds of scenarios, including guests asking for GIC but
failing to specify a version, guests specifying an invalid version
and guests trying to use GIC with non-virt or even non-ARM machines.
Unify the naming to prepare for new test cases that will be added

Convert a couple of output XML files for the qemuxml2xml test to

Moreover, since we're only interested in testing GIC support here,
simplify XML files by getting rid of the unrelevant bits.
After the rework of mocking of our tests there's the
virportallocator test failing to link on mingw. Well, it's the
mocking library actually:

I've no idea why this matters to mingw and does not to others.
Nevertheless, if we make the test linux only the problem goes
away.
Apparently, our test for RTLD_NEXT is not sufficient because
mingw32 defines it. Lets put aside for a while fact that it has
the same value as RTLD_DEFAULT which by description has different
meaning, shall we?

Mock libraries should not be linked against libvirt, but some of
them did - fix that.
On the other hand, not linking against gnulib can cause build
failures on mingw, so define a new $(MOCKLIBS_LIBS) variable and
use it everywhere.
The virportallocatortest.c file is compiled both as a test case
and as a mock library; in the latter case, it can't use
VIR_FORCE_CLOSE() because mock libraries are not linked against
libvirt.
Replace VIR_FORCE_CLOSE() with plain close() to solve the issue.
Apparently we are not the only ones with dumb free functions
because dbus_message_unref() does not accept NULL either. But if
I were to vote, this one is even more evil. Instead of returning
an error just like we do it immediately dereference any pointer
passed and thus crash you app. Well done DBus!

Extract out the qemuParseCommandLine{String|Pid} into their own

Mock libraries are used with LD_PRELOAD from test binaries that
are already linked against those libraries, so they will be able
to resolve the symbols anyway.
We use the PreFormat callback for this. Many test cases need to be extended
to pass in proper qemuCaps flags so AssignAddresses doesn't throw errors.
One test case (pcie-root-port-too-many) is dropped, since it was meant
only for checking an error condition in qemuxml2argv, and one we add in
AssignAddresses it errors here too.
Long term I think AssignAddresses should be handled in qemu's PostParse
callback, but that's not entirely straightforward. Handling it here
means we can get the test suite churn over with.
The virStringListLength function does not ever modify the passed
string list. It merely counts the items in it. Make sure that we

(crobinso: fix up spacing and squash in sheepdog bit suggested
by Andrea)
When we unconditionally enable QEMU_CAPS_DEVICE, these tests need
some massaging, so do it ahead of time to not mix it in with the
big test refresh.
- minimal-s390 is not a real world working config, so drop it
- disk-usb was testing for an old code path that will be removed.
instead use it to test lack of USB disk support, and rename it
to disk-usb-nosupport. Switch xml2xml to use disk-usb-device for
input.
- cputune-numatune was needlessly using q35, switch it to an older
machine type
Most qemuxml2xml tests expect that the input XML is unchanged after
parsing. This is unlike 99% of new qemu configs in the wild, which after
initial parsing end up with stable PCI device addresses. The xml2xml bit
doesn't currently hit that code path though, so most XML testing indeed
does not change.
Future patches will add that PCI address bits, which means most test cases
will have different output. So let's do away with the hardcoded same vs
different test split, and always track a separate output file. Tests can
still have same input and output, it just necessitates 2 separate XML files.
