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.

Commit 55320c23 introduced a new test for VNC to test if
vnc_auto_unix_socket is set in qemu.conf, but forget to enable it in
qemuxml2argvtest.c.
This patch also moves the code in qemuxml2xmltest.c next to other VNC
tests and refactor the test so we also check the case for parsing active
XML.

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.
We support omitting listen attribute of graphics element so we should
also support omitting address attribute of listen element. This patch

The only QEMU versions that don't have such capability are <0.12,
which we no longer support anyway.
Additionally, this solves the issue of some QEMU binaries being
reported as not having such capability just because they lacked
the {kvm-}pci-assign QMP object.
For a few cases where we handle secret information it's good to clear
the buffers containing sensitive data before freeing them.
Introduce VIR_DISPOSE, VIR_DISPOSE_N and VIR_DISPOSE_STRING that allow
simple clearing fo the buffers holding sensitive information on cleanup
paths.
When -cpu host is supported by a QEMU binary, a user can use
<cpu mode='host-passthrough'/> in domain XML even when libvirtd failed
to find a matching model for the host CPU. Let's make it obvious by
advertising <cpuselection/> guest capability whenever -cpu host is
supported.

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
wrapper that calls desired function from glibc.

Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
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
predictable results wrt default video RAM size.

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.

Now that we have all the pieces in place, we can add the 'iothread=#' to
the command line for the (two) controllers that support it (virtio-scsi-pci
and virtio-scsi-ccw). Add the tests as well...
Add the ability to add an 'iothread' to the controller which will be how
virtio-scsi-pci and virtio-scsi-ccw iothreads have been implemented in qemu.
Describe the new functionality and add tests to parse/validate that the
new attribute can be added.
An iothread for virtio-scsi is a property of the controller. Add a lookup
of the 'virtio-scsi-pci' and 'virtio-scsi-ccw' device properties and parse
the output. For both, support for the iothread was added in qemu 2.4
while support for virtio-scsi in general was added in qemu 1.4.
Modify the various mock capabilities replies (by hand) to reflect the
when virtio-scsi was supported and then specifically when the iothread
property was added. For versions prior to 1.4, use the no device error
return for virtio-scsi. For versions 1.4 to before 2.4, add some data
for virtio-scsi-pci even though it isn't complete we're not looking for
anything specific there anyway. For 2.4 to 2.6, add a more complete reply.

Our socket address format is in a rather non-standard format and that is
because sasl library requires the IP address and service to be delimited by a
semicolon. The string form is a completely internal matter, however once the
admin interfaces to retrieve client identity information are merged, we should
return the socket address string in a common format, e.g. format defined by
URI rfc-3986, i.e. the IP address and service are delimited by a colon and
in case of an IPv6 address, square brackets are added:
Examples:
127.0.0.1:1234
[::1]:1234

Admin API needs a way of addressing specific clients. Unlike servers, which we
are happy to address by names both because its name reflects its purpose (to
some extent) and we only have two of them (so far), naming clients doesn't make
any sense, since a) each client is an anonymous, i.e. not recognized after a
disconnect followed by a reconnect, b) we can't predict what kind of requests
it's going to send to daemon, and c) the are loads of them comming and going,
so the only viable option is to use an ID which is of a reasonably wide data
type.

If qemu doesn't support DEVICE_TRAY_MOVED event the code that attempts
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.

This unifies the test scripts to all use the similar pattern added for

- 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

According to the dnsmasq manpage, the netmask for IPv4 address ranges
will be auto-deteremined from the interface dnsmasq is listening on,

incorrect, dnsmasq will refuse to give out an address to clients,
instead logging this message:
