Turns out that it's not enough to pass the qemu:///embed root to
virQEMUDriverConfigNew(), you also have to make sure the same
string is copied into the virQEMUDriver structure yourself, and
not doing so in our case resulted in the cleanup never happening
and in distcheck failing because of that.
On the other hand, actually setting config->embeddedRoot would
result in different paths being generated for each test run, which
would obviously break qemuxml2argvtest, so that's not an option

The qemuMonitorTestNew() function returns with the monitor object
locked, and expects it to still be locked when qemuMonitorTestFree
is called. The qemuhotplug test, however, explicitly unlocks the
monitor, but then forgets to lock it again. As a result the
qemuMonitorTestFree function is unlocking a mutex it doesn't own.
This bug has existed forever, but since we use normal POSIX mutexes
and don't check the return value of pthread_mutex_lock/unlock we
didn't see the error. It was harmless until the switch to the per

Some of our tests try to validate domain XMLs they are working
with (not intentionally, simply because they call top level
domain XML parse function). Anyway, this implies that we build
domain capabilities also - see
virQEMUDriverGetDomainCapabilities(). And since some domain XMLs
are type of 'kvm' the control gets through
virQEMUCapsFillDomainCaps() and virHostCPUGetKVMMaxVCPUs() to
opening /dev/kvm which may be missing on the machine we're
running 'make check'.
Previously, we did not see this issue, because it was masked. If
building domain capabilities failed for whatever reason, we
ignored the failure. Only v5.9.0-207-gc69e6edea3 uncovered the
problem (it changed reval from 0 to -1 if

(currently, only tests/qemuhotplugtest.c).
Previous patch deprecated the variable, using qemu_driver->unplugTimeout

For some architectures and setups, device removal can take
longer than the default 5 seconds. This results in commands
such as 'virsh setvcpus' to fire timeout messages even if
the operation were successful in the guest, confusing the
user.
This patch sets a new 10 seconds unplug timeout for PPC64
guests. All other archs will keep the default 5 seconds
timeout.
Instead of putting 'if PPC64' conditionals inside qemu_hotplug.c
to set the new timeout value, a new function called
qemuDomainGetUnplugTimeout was added. The timeout value is then
retrieved when needed, by passing the correspondent DomainDef
object. This approach allows for different guest architectures
to have distint unplug timeout intervals, regardless of the
host architecture. This design also makes it easier to
modify/enhance the unplug timeout logic in the future
(allow for special timeouts for TCG domains, for example).
A new mock file was created to work with qemuhotplugtest.c,
given that the test timeout is significantly shorter than
the actual timeout value in qemu_hotplug.c.
The now unused 'qemuDomainRemoveDeviceWaitTime' global can't
be simply erased from qemu_hotplug.c though. Next patch will
remove it properly.

The test monitor should be freed separately so we need to remove the

The cpu hotplug operation is rather complex so the testing code needs to
provide quite lot of data and monitor conversations to successfully test
it. The code mainly tests the selection of cpus according to the target
count request.
If libvirtd is running unprivileged, it can open a device's PCI config
data in sysfs, but can only read the first 64 bytes. But as part of
determining whether a device is Express or legacy PCI,
qemuDomainDeviceCalculatePCIConnectFlags() will be updated in a future
patch to call virPCIDeviceIsPCIExpress(), which tries to read beyond
the first 64 bytes of the PCI config data and fails with an error log
if the read is unsuccessful.
In order to avoid creating a parallel "quiet" version of
virPCIDeviceIsPCIExpress(), this patch passes a virQEMUDriverPtr down
through all the call chains that initialize the
qemuDomainFillDevicePCIConnectFlagsIterData, and saves the driver
pointer with the rest of the iterdata so that it can be used by
qemuDomainDeviceCalculatePCIConnectFlags(). This pointer isn't used
yet, but will be used in an upcoming patch (that detects Express vs
legacy PCI for VFIO assigned devices) to examine driver->privileged.

regression.
In this commit, some files are duplicated because of the way
qemuhotplug.c calculates the expected xml filenames.
I plan on changing that to explicitly stating the basis domain
xml, the device xml, and the expected xml.
This way we can safely differentiate what XMLs contain whole domain
definitions and which contain just devices. Thanks to that we can
test the domain XMLs in virschematest again.

This makes the search for related XMLs easier, plus they are not used in
the xml2argv tests anyway. This also makes future patches cleaner.
While on that remove unnecessary '-hotplug' from the filenames.

Verify that SCSI controllers get created automatically when a SCSI disk
is hot-plugged to a domain that doesn't have a matching SCSI controller
defined already.

Since commit 7140807917, qemu agent
channel cannot be plugged in because we won't generate its path
automatically. Let's not only fix that, but also add tests for it so
next time it's checked for.

Until now, the only hot thing in this test was the name. That's because
we set the id to '-1' before every test. With this change, we test the
hotplug on live domains as the name suggests and as it should be.

In qemuHotplugCreateObjects, the ret variable was filled by
the value returned by qemuTestCapsCacheInsert.
If any of the functions after this assignment failed, we would still
return success.
Also adjust testCompareXMLToArgvHelper, where this change is just
cosmetic, because the value was overwritten right away.
After 9c17d665fd the tap device for ethernet network type is
automatically precreated before spawning qemu. Problem is, the
qemuxml2argvtest wasn't updated and thus is failing. Because of
all the APIs that new code is calling, I had to mock a lot. Also,
since the tap FDs are labeled separately from the rest of the
devices/files I had to enable NOP security driver for the test
too.
