db873ab3bc qemu: Adapt to changed ppc64 CPU model names
QEMU 2.11 for ppc64 changed all CPU model names to lower case. Since
libvirt can't change the model names for compatibility reasons, we need
to translate the matching lower case models to the names known by
libvirt.

2674d00ed4 qemu: Drop MSR features from host-model with old QEMU
With QEMU versions which lack "unavailable-features" we use CPUID based
detection of features which were enabled or disabled once QEMU starts.
Thus using MSR features with host-model would result in all of them
being marked as disabled in the active domain definition even though
QEMU did not actually disable them.

Let's make sure we add MSR features to host-model only when
"unavailable-features" property is supported by QEMU.

4586b11bed tests: qemucaps: Update 4.1.0 capabilities to a more recent version
Update the capabilities from a non-upstream version (9c70209b63 is not
in qemu.git) to qemu upstream commit 33d6099906 (2019/06/18) so that we
get the QMP schema 'features' field support and are able to detect that
the 'file' block backend supports dynamic auto-read-only.

Note that I've rebuilt this on a machine with a more modern kernel and
microcode which exposes e.g. the recent CPU bug mitigations, thus I
opted to keep the CPU changes rather than trying to do a franken-caps
by updating only the output of query-qmp-schema.

5b9819eedc domain capabilities: Expose firmware auto selection feature
If a management application wants to use firmware auto selection
feature it can't currently know if the libvirtd it's talking to
support is or not. Moreover, it doesn't know which values that
are accepted for the @firmware attribute of <os/> when parsing
will allow successful start of the domain later, i.e. if the mgmt
application wants to use 'bios' whether there exists a FW
descriptor in the system that describes bios.

This commit then adds 'firmware' enum to <os/> element in
<domainCapabilities/> XML like this:

  <enum name='firmware'>
    <value>bios</value>
    <value>efi</value>
  </enum>

We can see both 'bios' and 'efi' listed which means that there
are descriptors for both found in the system (matched with the
machine type and architecture reported in the domain capabilities
earlier and not shown here).

ad12932481 tests: domcaps: Remove 'full' test
The 'full' test verifies the output of a virDomainCapsPtr built
by hand. It has the following problems:

The domcaps test suite nowadays has 3 hypervisor driver implementations
which should give us plenty of opportunity to get full domcaps coverage.
I don't think this test has much value. And it has the following issues:

- Requires manual intervention to test new domcaps XML, which is easy
  to miss, for example gic bits aren't covered there.
- The SET_ALL_BITS trick it uses to fill in enums will output
  values that are never reported by any driver implementation
  (strings like 'default')

Let's remove it

d21f89cc1a conf: Introduce VIR_DOMAIN_LOADER_TYPE_NONE

once loader path is NULL its type makes no sense. However, since
value of zero corresponds to VIR_DOMAIN_LOADER_TYPE_ROM the

  <os>

To solve this, introduce VIR_DOMAIN_LOADER_TYPE_NONE which would
correspond to value of zero and then use post parse callback to
set the default loader type to 'rom' if needed.

77f51ab520 qemu: caps: Format SEV platform data into qemuCaps cache
Since we're not saving the platform-specific data into a cache, we're
not going to populate the structure, which in turn will cause a crash
upon calling virNodeGetSEVInfo because of a NULL pointer dereference.
Ultimately, we should start caching this data along with host-specific
capabilities like NUMA and SELinux stuff into a separate cache, but for
the time being, this is a semi-proper fix for a potential crash.

Backtrace (requires libvirtd restart to load qemu caps from cache):

Historically, we've always enabled an emulated video device every time we

Therefore introduce a new, effectively a 'disable', type for video

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).

385c1cc96c qemu: Check non-migratable host CPU features
CPU features which change their value from disabled to enabled between
two calls to query-cpu-model-expansion (the first with no extra
properties set and the second with 'migratable' property set to false)
can be marked as enabled and non-migratable in qemuMonitorCPUModelInfo.

Since the code consuming qemuMonitorCPUModelInfo currently ignores the
migratable flag, this change is effectively changing the CPU model
advertised in domain capabilities to contain all features (even those
which block migration). And this matches what we do for QEMU older than
2.9.0, when we detect all CPUID bits ourselves without asking QEMU.

As a result of this change

    <cpu mode='host-model'>
      <feature name='invtsc' policy='require'/>
    </cpu>

will work with all QEMU versions. Such CPU definition would be forbidden
with QEMU >= 2.9.0 without this patch.

bb3363c90b qemu: Use full CPU model expansion on x86
The static CPU model expansion is designed to return only canonical
names of all CPU properties. To maintain backwards compatibility libvirt
is stuck with different spelling of some of the features, but we need to
use the full expansion to get the additional spellings. In addition to
returning all spelling variants for all properties the full expansion
will contain properties which are not guaranteed to be migration
compatible. Thus, we need to combine both expansions. First we need to
call the static expansion to limit the result to migratable properties.
Then we can use the result of the static expansion as an input to the
full expansion to get both canonical names and their aliases.
