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.
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
later on.
Convert a couple of output XML files for the qemuxml2xml test to
symlinks while at it, since they were identical to the corresponding
input XML files anyways.
Moreover, since we're only interested in testing GIC support here,
simplify XML files by getting rid of the unrelevant bits.
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
Some of the tests that are not a part of qemuBuildCommandLine were not
executed in the test suite. We can now reuse qemuProcessStartValidate to
integrate these tests.
Those tests are in qemuargv2xmltest and it makes sense to include them
also in qemuxml2xmltest and qemuxml2argvtest.

Autodeflate can be enabled/disabled for memballon device
of model 'virtio'.
xml:
<devices>
<memballoon model='virtio' autodeflate='on'/>
</devices>
qemu:
qemu -device virtio-balloon-pci,...,deflate-on-oom=on
Autodeflate cannot be enabled/disabled for running domain.
Use virDomainDefAddUSBController() to add an EHCI1+UHCI1+UHCI2+UHCI3
controller set to newly defined Q35 domains that don't have any USB
controllers defined.
The real Q35 machine puts the first USB controller set (EHCI+(UHCIx4))
on bus 0 slot 0x1D, and the 2nd USB controller set on bus 0 slot 0x1A,
so let's attempt to make the virtual machine match that for
controllers with auto-assigned addresses when possible.
Three test cases were added to assure that the proper addresses are
assigned - one with a single set of unaddressed USB controllers, one
with 3 (to grab both preferred slots plus one more), and one with the
order of the controller definitions reordered, to assure that the
auto-assignment isn't mixed up by order.
If the q35 specific disable s3/s4 setting isn't supported, fallback to
specifying the PIIX setting, which is the previous behavior. It doesn't
have any effect, but qemu will just warn about it rather than error:
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s3=1 not used
qemu-system-x86_64: Warning: global PIIX4_PM.disable_s4=1 not used
Since it doesn't error, I don't think we should either, since there
may be configs in the wild that already have q35 + disable_s3/4 (via
virt-manager)
The condition was checking for UHCI (and OHCI for ppc64) availability so
that it can specify the proper device instead of legacy usb. However,
for ppc64, we don't need to check both OHCI and UHCI, but only OHCI as
that is the legacy default. The condition is so big that it was just a
matter of time when someone will make a mistake there, so let's use more
lines so that it is visible what the condition checks for.
This fixes usage of -device instead of -usb for ppc64 that supports
pci-usb-ohci and does not support piix3-usb-uhci.

Since libvirt for dubious historical reasons stores memory size as
kibibytes, it's possible that the alignments done in the qemu code
overflow the the maximum representable size in bytes. The XML parser
code handles them in bytes in some stages. Prevent this by doing
overflow checks when alinging the size and add a test case.

'model' attribute was added to a panic device but only one panic
device is allowed. This patch changes panic device presence
from 'optional' to 'zeroOrMore'.
Panic device type used depends on 'model' attribute.
If no model is specified then device type depends on hypervisor
and guest arch. 'pseries' model is used for pSeries guest and
'isa' model is used in other cases.

<devices>
<panic model='hyperv'/>

When qemuDomainPinIOThread was added in commit id 'fb562614', a check
for the IOThread capability was not needed since a check for iothreadpids
covered the condition where the support for IOThreads was not present.
The iothreadpids array was only created if qemuProcessDetectIOThreadPIDs
was able to query the monitor for IOThreads. It would only do that if
the QEMU_CAPS_OBJECT_IOTHREAD capability was set.
However, when iothreadids were added in commit id '8d4614a5' and the
check for iothreadpids was replaced by a search through the iothreadids[]
array for the matching iothread_id that left open the possibility that
an iothreadids[] array was defined, but the entries essentially pointed
to elements with only the 'iothread_id' defined leaving the 'thread_id'
value of 0 and eventually the cpumap entry of NULL.
This was because, the original IOThreads commit id '72edaae7' only
checked if IOThreads were defined and if the emulator had the IOThreads
capability, then IOThread objects were added at startup. The "capability
failure" check was only done when a disk was assigned to an IOThread in
qemuCheckIOThreads. This was because the initial implementation had no way
to dynamically add IOThreads, but it was possible to dynamically add a
disk to the domain. So the decision was if the domain supported it, then
add the IOThread objects. Then if a disk with an IOThread defined was
added, it could check the capability and fail to add if not there. This
just meant the 'iothreads' value was essentially ignored.
Eventually commit id 'a27ed6e7' allowed for the dynamic addition and
deletion of IOThread objects. So it was no longer necessary to generate
IOThread objects to dynamically attach a disk to. However, the startup
and disk check code was not modified to reflect this.
This patch will move the capability failure check to when IOThread
objects are being added to the command line. Thus a domain that has
IOThreads defined will not be started if the emulator doesn't support
the capability. This means when qemuCheckIOThreads is called to add
a disk, it's no longer necessary to check the capability. Instead the
code can use the IOThreadFind call to indicate that the IOThread
doesn't exist.
Finally because it could be possible to have a domain running with the
iothreadids[] defined prior to this change if libvirtd is restarted each
having mostly empty elements, qemuProcessDetectIOThreadPIDs will check
if there are niothreadids when the QEMU_CAPS_OBJECT_IOTHREAD capability
check fails and remove the elements and array if it exists.
With these changes in place, it turns out the cputune-numatune test
was failing because the right bit wasn't set in the test. So used the
opportunity to fix that and create a test that would expect to fail
with some sort of iothreads defined and used, but not having the
correct capability.

Adds a new interface type using UDP sockets, this seems only applicable
to QEMU but have edited tree-wide to support the new interface type.
The interface type required the addition of a "localaddr" (local
address), this then maps into the following xml and qemu call.
<interface type='udp'>
<mac address='52:54:00:5c:67:56'/>
<source address='127.0.0.1' port='11112'>
<local address='127.0.0.1' port='22222'/>
</source>
<model type='virtio'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
</interface>
QEMU call:
-net socket,udp=127.0.0.1:11112,localaddr=127.0.0.1:22222
Notice the xml "local" entry becomes the "localaddr" for the qemu call.
