6e7e965dcd util: storage: Properly parse URIs with missing trailing slash
The URI parser used by libvirt does not populate uri->path if the
trailing slash is missing. The code virStorageSourceParseBackingURI
would then not populate src->path.

As only NBD network disks are allowed to have the 'name' field in the
XML defining the disk source omitted we'd generate an invalid XML which
we'd not parse again.

Fix it by populating src->path with an empty string if the uri is
lacking slash.

As pointed out above NBD is special in this case since we actually allow
it being NULL. The URI path is used as export name. Since an empty
export does not make sense the new approach clears the src->path if the
trailing slash is present but nothing else.

Add test cases now to cover all the various cases for NBD and non-NBD
uris as there was to time only 1 test abusing the quirk witout slash for
NBD and all other URIs contained the slash or in case of NBD also the
export name.

35966308b5 virsh: Fix regression with duplicated error messages
Commit 4f4c3b13 (v3.3) fixed an issue where performing cleanup of
libvirt objects could sometimes lose error messages, by adding code
to copy the libvirt error into last_error prior to cleanup paths.
However, it caused a regression: on other paths, some errors are now
printed twice, if libvirt still remembers in its thread-local
storage that an error was set even after virsh cleared last_error.
For example:

$ virsh -c test:///default snapshot-delete test blah
error: Domain snapshot not found: no domain snapshot with matching name 'blah'
error: Domain snapshot not found: no domain snapshot with matching name 'blah'

Fix things by telling libvirt to discard any thread-local errors at
the same time virsh prints an error message (whether or not the libvirt
error is the same as what is stored in last_error).

Update the virsh-undefine testsuite (partially reverting portions of
commit b620bdee, by removing -q, to more easily pinpoint which commands
are causing which messages), now that there is only one error message
instead of two.

1dbf6222dd virfile: Rework virFileIsSharedFixFUSE
There are couple of things wrong with the current implementation.
The first one is that in the first loop the code tries to build a
list of fuse.glusterfs mount points. Well, since the strings are
allocated in a temporary buffer and are not duplicated this
results in wrong decision made later in the code.

The second problem is that the code does not take into account
subtree mounts. For instance, if there's a fuse.gluster mounted
at /some/path and another FS mounted at /some/path/subdir the
code would not recognize this subdir mount.

98ca1d52a2 virFileIsSharedFSType: Detect direct mount points
If the given path is already a mount point (e.g. a bind mount of

a7b4eb7d26 virfiletst: Test virFileIsSharedFS
Introduce some basic test cases for virFileIsSharedFS(). More
will be added later. In order to achieve desired result, mocks
for setmntent() and statfs() need to be invented because the
first thing that virFileIsSharedFS() does is calling the latter.
If it finds a FUSE mount it'll call the former.

The mock might look a bit complicated, but in fact it's quite
simple. The test sets LIBVIRT_MTAB env variable to hold the
absolute path to a file containing mount table. Then, statfs()
returns matching FS it finds, and setmntent() is there just to
replace /proc/mounts with the file the test wants to load.

Adding this test also exposed a bug we have - because we assume
the given path points to a file we cut off what we assume is a
file name to obtain directory path and only then we call
statfs(). This is buggy because the passed path could be already
a mount point.

25456e0470 tests: reintroduce tests for libxl's legacy nested setting
The preferred location for setting the nested CPU flag changed in
Xen 4.10 and is advertised via the LIBXL_HAVE_BUILDINFO_NESTED_HVM
define.  Commit 95d19cd0 changed libxl to use the new preferred
location but unconditionally changed the tests, causing 'make check'
failures against Xen < 4.10 that do not contain the new location.

Commit e94415d5 fixed the failures by only running the tests when
LIBXL_HAVE_BUILDINFO_NESTED_HVM is defined. Since libvirt supports
several versions of Xen that use the old nested location, it is
prudent to test the flag is set correctly. This patch reintroduces
the tests for the legacy location of the nested setting.

In order to use virCgroupNewSelf we need to create all the remaining
data files:

    - {name}.cgroups represents /proc/cgroups, it is a list of cgroup
      controllers compiled into kernel

    - {name}.self.cgroup represents /proc/self/cgroup, it describes
      cgroups to which the process belongs

For "no-cgroups" we need to modify the expected behavior because
virCgroupNewSelf() will fail if there are no controllers available.

'kvmbin' is not defined, which is unnecessary as 'binary'
has been registered as default earlier, and will result
in capabilities output such as

  <emulator>/usr/bin/qemu-system-x86_64</emulator>
  <domain type='qemu'/>
  <domain type='kvm'>
    <emulator>/usr/bin/qemu-system-x86_64</emulator>
  </domain>

with the second <emulator> element providing no additional
information.

Change it so that, when 'kvmbin' is not defined, NULL is
passed and so the default emulator will be used instead.

6af8417415 conf: Introduce RDT monitor host capability
This patch is introducing cache monitor(CMT) to cache and
memory bandwidth monitor(MBM) for monitoring CPU memory
bandwidth.

The host capability of the two monitors is also introduced
in this patch.

For CMT, the host capability is shown like:
  <host>
  ...
    <cache>
      <bank id='0' level='3' type='both' size='15' unit='MiB' cpus='0-5'>
        <control granularity='768' min='1536' unit='KiB' type='both' maxAllocs='4'/>
      </bank>
      <monitor level='3' 'reuseThreshold'='270336' maxMonitors='176'>
        <feature name='llc_occupancy'/>
      </monitor>
    </cache>
    ...
  </host>

For MBM, the capability is shown like this:
  <host>
    ...
    <memory_bandwidth>
      <node id='1' cpus='6-11'>
        <control granularity='10' min ='10' maxAllocs='4'/>
      </node>
      <monitor maxMonitors='176'>
        <feature name='mbm_total_bytes'/>
        <feature name='mbm_local_bytes'/>
      </monitor>
    </memory_bandwidth>

3e26b476b5 security_manager: Load lock plugin on init
Now that we know what metadata lock manager user wishes to use we
can load it when initializing security driver. This is achieved
by adding new argument to virSecurityManagerNewDriver() and
subsequently to all functions that end up calling it.

The cfg.mk change is needed in order to allow lock_manager.h
inclusion in security driver without 'syntax-check' complaining.
This is safe thing to do as locking APIs will always exist (it's
only backend implementation that changes). However, instead of
allowing the include for all other drivers (like cpu, network,
and so on) allow it only for security driver. This will still
trigger the error if including from other drivers.

7ea7342996 conf: correct false boot order error during domain parse
virDomainDefCollectBootOrder() is called for every item on the list
for each type of device. One of the checks it makes is to gather the
order attributes from the <boot> element of all devices, and assure
that no two devices have been given the same order.

Since (internally to libvirt, *not* in the domain XML) an <interface
type='hostdev'> is on both the list of hostdev devices and the list of
network devices, it will be counted twice, and the code that checks
for multiple devices with the same boot order will give a false
positive.

To remedy this, we make sure to return early for hostdev devices that
have a parent.type != NONE.

This was introduced in commit 5b75a4, which was first in libvirt-4.4.0.

614193fac6 conf: Fix check for chardev source path
Attempting to use a chardev definition like

  <serial type='unix'>
    <target type='isa-serial'/>
  </serial>

correctly results in an error being reported, since the source
path - a required piece of information - is missing; however,
the very similar

  <serial type='unix'>
    <target type='pci-serial'/>
  </serial>

was happily accepted by libvirt, only to result in libvirtd
crashing as soon as the guest was started.

The issue was caused by checking the chardev's targetType
against whitelisted values from virDomainChrChannelTargetType
without first checking the chardev's deviceType to make sure
it is actually a channel, for which the check makes sense,
rather than a different type of chardev.

The only reason this wasn't spotted earlier is that the
whitelisted values just so happen to correspond to USB and
PCI serial devices and Xen and UML consoles respectively,
all of which are fairly uncommon.

39015a6f3a tests: rewrite socket to do something sensible and reliable
The current socket test is rather crazy in that it sets up a server
listening for sockets and then runs a client connect call, relying on
the fact that the kernel will accept this despite the application
not having called accept() yet. It then closes the client socket and
calls accept() on the server. On Linux accept() will always see that
the client has gone and so skip the rest of the code. On FreeBSD,
however, the accept sometimes succeeds, causing us to then go into
code that attempts to read and write to the client which will fail
aborting the test. The accept() never succeeds on FreeBSD guests
with a single CPU, but as you add more CPUs, accept() becomes more and
more likely to succeed, giving a 100% failure rate for the test when
using 8 CPUs.

This completely rewrites the test so that it is avoids this designed in
race condition. We simply spawn a background thread to act as the
client, which will read a byte from the server and write it back again.
The main thread can now properly listen and accept the client in a
synchronous manner avoiding any races.

7469aa0bc2 tests: skip some unicode tests if expected output won't match
The expected output strings from the vshtabletest.c are created on a
modern Linux host where unicode printing support is very good. On older
Linux platforms, or non-Linux platforms, some unicode characters will
not be considered printable. While the vsh table alignment code will
stil do the right thing with escaping & aligning in this case, the
result will not match the test's expected output.

Since we know the code is working correctly, do a check with iswprint()
to validate the platform's quality and skip the test if it fails. This
fixes the test on FreeBSD platforms.

d8313d3cf2 tests: Properly reset mocked CPU model
When switching the host architecture to something for which we do not
have any host CPU model defined, the mocked
virQEMUCapsProbeHostCPUForEmulator would just return the previous CPU
model resulting in strange combinations, such as "core2duo" host CPU
model in QEMU capabilities for "AArch64" architecture. It currently
doesn't break any test case, but we should fix it anyway to avoid future

fe67e3e28e qemu: Validate memory access during validate domain config
Commit 6534b3c4 tried to raise an error when there is no numa
nodes by setting access='shared' in the domain config, but added
a helper called from qemuDomainDeviceDefValidate instead of a
helper called from qemuDomainDefValidate for XML:

  <memoryBacking>
    <hugepages/>
    <access mode='shared'/>
  </memoryBacking>

Since there are no memory devices in the test XML, there would
be no validation failure, but the test added was still failing.
Investigating that it turns out that unnecessary XML elements
were causing the failure (no need for <video>, <graphics>,
<pm>, usb controller model "piix3-uhci", disk attribute for
"discard='unmap'", <serial>, <console>, <channel> and a
memballoon model). Removing all those before moving the method
caused the test to succeed.

So this patch moves the validation to the right place and
removes all the unnecessary XML pieces that were causing
a false validation failure.

replace the new unicode characters causing issues with some older ones

Since we're not saving the platform-specific data into a cache, we're

upon calling virNodeGetSEVInfo because of a NULL pointer dereference.
Ultimately, we should start caching this data along with host-specific

the time being, this is a semi-proper fix for a potential crash.

764491c9dd qemu: Fix probing of AMD SEV support
So the procedure to detect SEV support works like this:
1) we detect that sev-guest is among the QOM types and set the cap flag
2) we probe the monitor for SEV support
    - this is tricky, because QEMU with compiled SEV support will always
    report -object sev-guest and query-sev-capabilities command, that
    however doesn't mean SEV is supported
3) depending on what the monitor returned, we either keep or clear the
capability flag for SEV

Commit a349c6c21c added an explicit check for "GenericError" in the
monitor reply to prevent libvirtd to spam logs about missing
'query-sev-capabilities' command. At the same time though, it returned
success in this case which means that we didn't clear the capability
flag afterwards and happily formatted SEV into qemuCaps. Therefore,
adjust all the relevant callers to handle -1 on errors, 0 on SEV being

6c50cef8a3 tests: sev: Test launch-security with specific QEMU version
In order to test SEV we need real QEMU capabilities. Ideally, this would
be tested with -latest capabilities, however, our capabilities are
currently tied to Intel HW, even the 2.12.0 containing SEV were edited by
hand, so we can only use that one for now, as splitting the capabilities
according to the vendor is a refactor for another day. The need for real
capabilities comes from the extended SEV platform data (PDH, cbitpos,
etc.) we'll need to cache/parse.

As advertised in the previous commit, we need the list of

appear on the list. Not only this enables us to fine tune our

7135cee755 check-file-access: Allow specifying action
The check-file-access.pl script is used to match access list
generated by virtestmock against whitelisted rules stored in
file_access_whitelist.txt. So far the rules are in form:

  $path: $progname: $testname

This is not sufficient because the rule does not take into
account 'action' that caused $path to appear in the list of
accessed files. After this commit the rule can be in new form:

  $path: $action: $progname: $testname

where $action is one from ("open", "fopen", "access", "stat",
"lstat", "connect"). This way the white list can be fine tuned to
allow say access() but not connect().

So far we are setting only fake secret and storage drivers.
Therefore if the code wants to call a public NWFilter API (like
qemuBuildInterfaceCommandLine() and qemuBuildNetCommandLine() are
doing) the virGetConnectNWFilter() function will try to actually
spawn session daemon because there's no connection object set to
handle NWFilter driver.

of the drivers (interface, network and node dev), the reasoning

0a476f1521 conf: Introduce virDomainDefPostParseMemtune
Previously we were ignoring "nodeset" attribute for hugepage pages
if there was no guest NUMA topology configured in the domain XML.
Commit <fa6bdf6afa878b8d7c5ed71664ee72be8967cdc5> partially fixed
that issue but it introduced a somehow valid regression.

In case that there is no guest NUMA topology configured and the
"nodeset" attribute is set to "0" it was accepted and was working
properly even though it was not completely valid XML.

This patch introduces a workaround that it will ignore the nodeset="0"
only in case that there is no guest NUMA topology in order not to
hit the validation error.

After this commit the following XML configuration is valid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
    </hugepages>
  </memoryBacking>

but this configuration remains invalid:

  <memoryBacking>
    <hugepages>
      <page size='2048' unit='KiB' nodeset='0'/>
      <page size='1048576' unit='KiB'/>
    </hugepages>
  </memoryBacking>

The issue with the second configuration is that it was originally
working, however changing the order of the <page> elements resolved
into using different page size for the guest.  The code is written
in a way that it expect only one page configured and always uses only
the first page in case that there is no guest NUMA topology configured.
See qemuBuildMemPathStr() function for details.

We allowed this configuration and it was working as expected therefore

silently ignore the 'nodeset' attribute if it's set to '0'.

Move the call back after formatting all disks and reiterate the disks to

This also moves the '-global' directive which sets up the default

in virFileFindResourceFull() from tests. The libvirtd no longer

Then, libvirtd-fail test was still failing (as expected) but not
because of missing config file but because it was trying to
execute (nonexistent) top_builddir/daemon/libvirtd which
fulfilled expected outcome and thus test did not fail.

Thirdly, lcov was told to generate coverage for daemon/ dir too.

Fourthly, our compiling documentation was still suggesting to run

When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages
sent by the handshake changes. This exposed a logic bug in the test
suite which caused us to wait for the server to see handshake
completion, but not wait for the client to see completion. The result
was the client didn't receive the certificate for verification and the
test failed.

This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in

mediated devices, IOW emulated GPU devices like QXL will no longer be

QEMU defaults to 'auto' for the 'display' attribute, which is not

d54e45b6ed conf: Introduce new <hostdev> attribute 'display'
QEMU 2.12 introduced a new type of display for mediated devices using
vfio-pci backend which allows a mediated device to be used as a VGA
compatible device as an alternative to an emulated video device. QEMU
exposes this feature via a vfio device property 'display' with supported
values 'on/off/auto' (libvirt will default to 'off').

This patch adds the necessary bits to domain config handling in order to
expose this feature. Since there's no convenient way for libvirt to come
up with usable defaults for the display setting, simply because libvirt
is not able to figure out which of the display implementations - dma-buf
which requires OpenGL support vs vfio regions which doesn't need OpenGL
(works with OpenGL enabled too) - the underlying mdev uses.

d8266ebe16 qemu: Introduce a new graphics display type 'headless'
Since 2.10 QEMU supports a new display type egl-headless which uses the
drm nodes for OpenGL rendering copying back the rendered bits back to
QEMU into a dma-buf which can be accessed by standard "display" apps
like VNC or SPICE. Although this display type can be used on its own,
for any practical use case it makes sense to pair it with either VNC or
SPICE display. The clear benefit of this display is that VNC gains
OpenGL support, which it natively doesn't have, and SPICE gains remote
OpenGL support (native OpenGL support only works locally through a UNIX
socket, i.e. listen type=socket/none).

to 2.5 since we don't use anything from newer versions.

Implement virJSONValue{From,To}String using Jansson, delete the yajl

ff767f083f qemu: command: Fix building of the SDL display command line
QEMU uses a shorthand '-sdl' which maps to '-display sdl'. However, if
there are any options to be passed to SDL, the full command version must
be used. Everything seemingly worked for us until commit 5038b30043
introduced OpenGL support for SDL and added ',gl=on/off' option which as
mentioned above could have never worked with the shorthand version of
the command. Indeed starting a domain with an SDL display and OpenGL
enabled, QEMU produces a rather cryptic error:

-sdl: Could not open 'gl=on': No such file or directory

This patch provides fixes to both the SDL cmdline generation and the
test suite.

ed5aa85f37 qemu: don't use chardev FD passing for vhostuser backend
QEMU chardevs have a bug which makes the vhostuser backend complain
about lack of support for FD passing when validating the chardev.
While this is ultimately QEMU's responsibility to fix, libvirt needs to
avoid tickling the bug.

Simply disabling chardev FD passing just for vhostuser's chardev is
the most prudent approach, avoiding need for a QEMU version number
check.

backend argument.

QEMU added the ability to set serial and geometry on the frontend in
the 1.2 release deprecating use of -drive, with support being deleted
from -drive in 3.0.

We keep formatting error policy on -drive for now, because we don't
ahve support for that with -device for usb-storage just yet.

Note that some disk buses (sd) still don't support -device. Although
QEMU allowed these properties to be set on -drive for if=sd, they
have been ignored so we now report an error in this case.

39cef12a95 storage: Add support for using inputvol for encryption
Starting with QEMU 2.9, encryption convert processing requires
a multi-step process in order to generate an encrypted image from
some non encrypted raw image.

Processing requires to first create an encrypted image using the
sizing parameters from the input source and second to use the
--image-opts, -n, and --target-image-opts options along with inline
driver options to describe the input and output files, generating
two commands such as:

  $ qemu-img create -f luks \
      --object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
      -o key-secret=demo.img_encrypt0 \
      demo.img 500K
  Formatting 'demo.img', fmt=luks size=512000 key-secret=demo.img_encrypt0
  $ qemu-img convert --image-opts -n --target-image-opts \
      --object secret,id=demo.img_encrypt0,file=/path/to/secretFile \
      driver=raw,file.filename=sparse.img \
      driver=luks,file.filename=demo.img,key-secret=demo.img_encrypt0
  $

This patch handles the convert processing by running the processing
in a do..while loop essentially reusing the existing create logic and
arguments to create the target vol from the inputvol and then converting
the inputvol using new arguments.

This then allows the following virsh command to work properly:

  virsh vol-create-from default encrypt1-luks.xml data.img --inputpool default

where encrypt1-luks.xml would provided the path and secret for
the new image, while data.img would be the source image.

e00ecd1bed tests: qemucapsprobemock: Prepare 'qemucapsprobe' for the new format
Change the output of qemucapsprobe to record the commands used for
querying. This allows to easily identify which reply belongs to which
command and also will allow to test whether we use stable queries.

This change includes changing dropping of the QMP greeting from the file
and reformatting of the query and output to stdout.

e5791a0306 conf: Introduce launch-security element in domain
The launch-security element can be used to define the security
model to use when launching a domain. Currently we support 'sev'.

When 'sev' is used, the VM will be launched with AMD SEV feature enabled.
SEV feature supports running encrypted VM under the control of KVM.
Encrypted VMs have their pages (code and data) secured such that only the
guest itself has access to the unencrypted version. Each encrypted VM is
associated with a unique encryption key; if its data is accessed to a
different entity using a different key the encrypted guests data will be
incorrectly decrypted, leading to unintelligible data.

3ea32b635d qemu: Add capability flag for setting the extended tseg size
For getting the reply I queried the newest and oldest QEMU using
test/qemucapsprobe.  From the differences I only extracted the reply to the new
QMP command and discarded the rest.  For all the versions below the one which
added support for the new option I used the output from the oldest QEMU release
and for those that support it I used the output from the newest one.

In order to make doubly sure the reply is where it is supposed to be (the
replies files are very forgiving) I added the property to all the replies files,
reran the tests again and fixed the order in replies files so that all the
versions are reporting the new capability.  Then removed that one property.

After that I used test/qemucapsfixreplies to fix the reply IDs.

1bd5a08d38 conf, schema, docs: Add support for TSEG size setting
TSEG (Top of Memory Segment) is one of many regions that SMM (System Management
Mode) can occupy.  This one, however is special, because a) most of the SMM code
lives in TSEG nowadays and b) QEMU just (well, some time ago) added support for
so called 'extended' TSEG.  The difference to the TSEG implemented in real q35's
MCH (Memory Controller Hub) is that it can offer one extra size to the guest OS
apart from the standard TSEG's 1, 2, and 8 MiB and that size can be selected in
1 MiB increments.  Maximum may vary based on QEMU and is way too big, so we
don't need to check for the maximum here.  Similarly to the memory size we'll
leave it to the hypervisor to try satisfying that and giving us an error message
in case it is not possible.

7ef0471bf7 qemu: don't retry connect() if doing FD passing
Since libvirt called bind() and listen() on the UNIX socket, it is
guaranteed that connect() will immediately succeed, if QEMU is running
normally. It will only fail if QEMU has closed the monitor socket by
mistake or if QEMU has exited, letting the kernel close it.

With this in mind we can remove the retry loop and timeout when
connecting to the QEMU monitor if we are doing FD passing. Libvirt can
go straight to sending the QMP greeting and will simply block waiting
for a reply until QEMU is ready.

30fb2276d8 qemu: support passing pre-opened UNIX socket listen FD
There is a race condition when spawning QEMU where libvirt has spawned
QEMU but the monitor socket is not yet open. Libvirt has to repeatedly
try to connect() to QEMU's monitor until eventually it succeeds, or
times out. We use kill() to check if QEMU is still alive so we avoid
waiting a long time if QEMU exited, but having a timeout at all is still
unpleasant.

With QEMU 2.12 we can pass in a pre-opened FD for UNIX domain or TCP
sockets. If libvirt has called bind() and listen() on this FD, then we
have a guarantee that libvirt can immediately call connect() and
succeed without any race.

Although we only really care about this for the monitor socket and agent
socket, this patch does FD passing for all UNIX socket based character
devices since there appears to be no downside to it.

We don't do FD passing for TCP sockets, however, because it is only
possible to pass a single FD, while some hostnames may require listening
on multiple FDs to cover IPv4 and IPv6 concurrently.
