+Subject: [PATCH] conf: Add fields for recording actually-selected virtio video
+ device
+
+QEMU's commandline generator picks for virtio video between various
+actual device models not only based on the XML definition but also
+capabilities present. Since none of the devices is actually ABI
+compatible we need to record the actually selected device in the XML.
+
+Introduce 'device' attribute:
+
+      <video>
+        <model type='virtio' heads='1' primary='yes' device='virtio-gpu'/>
+
+which will record the actually selected model so that we can preserve
+ABI across restarts on deployment changes but more importantly across
+migrations where the deployment differs.
+
+The code specifically avoids an ABI stability check for the new field
+because there are already possibly broken configurations that the users
+may want to fix by picking the proper model which could be forbidden.
+
+Users are instructed to not set the field in the XML.

+Subject: [PATCH] qemu: Allow reuse of 'qemuProcessStartUpdateCustomCaps'
+
+Move and rename the function to 'qemuDomainUpdateCustomCapabilities' and
+modify the arguments so that it will be possible to reuse it also in the
+post-parse and validation code which ought to base decisions on the same
+logic as VM startup would.
+
+Since copying of the qemu capabilities object is very expensive (I've
+observed an almost 4x slowdown of qemuxmlconftest)
+'qemuDomainUpdateCustomCapabilities' copies the capabilities only when
+necessary.

+Subject: [PATCH] qemu: capabilities: Apply 'capability_filters' configration
+ option on all capabilities
+
+The 'capability_filters' allows admins to globally disable some qemu
+capabilities via the config file.
+
+Until now it was applied only directly when starting the VM, but that is
+too late as the capability is still present when e.g. the post-parse
+code is picking defaults.
+
+Rework the code so that 'capability_filters' is applied directly after
+probing qemu so all existing capabilities will lack the filtered out
+ones.

+Subject: [PATCH] qemu: postparse: Fill in selected virtio video frondend
+ device in the XML
+
+Historically 'virtio-vga' was always picked as the first '<video>'
+(virtio) device and any sub-sequent ones were 'virtio-gpu'. When support
+for aarch64 VMs was being added an exception to use 'virtio-gpu' for the
+primary device was added as aarch64 doesn't have anything resembling the
+"legacy" 'VGA' interface. At this point this exception was only for
+aarch64. The distinction between 'virtio-vga' and 'virtio-gpu' was *not*
+recorded in the VM XML as it was a new feature (for aarch64) and it
+didn't make sense to pick 'virtio-vga'.
+
+Some time later the following commit:
+

+      qemu_command: properly detect which model to use for video device
+
+      This improves commit 706b5b6277 in a way that we check qemu capabilities
+      instead of what architecture we are running on to detect whether we can
+      use *virtio-vga* model or not.  This is not a case only for arm/aarch64.
+
+modified the code to do this picking by checking presence of
+'virtio-vga' device instead. That approach didn't consider the fact that
+the modular deployment of qemu allows for the 'virtio-vga' device to be
+missing in certain cases, thus introducing a latent bug as we'll pick
+'virtio-gpu' in such case but don't record it anywhere.
+
+Now this creates a problem, if the deployments differ, because you can
+have two *incompatible* (at migration stream level) setups which are
+based on the same identical XML without the possibility for the
+destination libvirt instance during migration to pick which is the
+correct one.
+
+To prevent this and actually fix any existing such deployment (which
+allows upgrade of libvirt daemons on the source) we will record the
+picked device frontend at post-parse time into the XML. This luckily
+properly handles running VMs even if 'virtio-vga' were already
+installed since we record the actual qemuCaps we've started the VM with.
+
+Now 'virtio-vga' vs 'virtio-gpu' is not the only broken piece of logic.
+In fact 'virtio-vga-gl' could have been downgraded to 'virtio-vga' based
+on some very weird logic (see comments in code for explanation).
+
+The logic in 'qemuDomainDeviceVideoDefPostParse' re-creates the logic
+used to setup virtio-vga vs. virtio-gpu, and 'vhost-user-vga' vs.
+'vhost-user-gpu' as those still make sense. For the 'gl' variants two
+versions exist, one meant to recover running VMs and one for new VMs
+where the broken logic makes no sense.
+
+Now this patch just records what was selected into the XML, but doesn't
+yet modify the commandline to actually use that value verbatim (e.g. if
+the user specified an actual non-default value already).

+Subject: [PATCH] qemu: postparse: Process VM config with qemuCaps influenced
+ by <qemu:capabilities>
+
+The user configuration of added/removed qemu capabilities via the qemu
+namespace element was applied only right before generating a
+commandline, but the post parse code code didn't see these.
+
+Apply the capability modification prior to running post parse code so
+that defaults are properly picked based on the configuration.

+
+The user configuration of added/removed qemu capabilities via the qemu
+namespace element was applied only right before generating a
+commandline, but the validation code didn't see these.
+
+Modify the validation entry points so that they apply this optionally.

+Subject: [PATCH] qemuDeviceVideoGetModel: Directly return picked model
+
+There's no point in falling through to the check reporting invalid
+type since if the code picks a model that one will be valid.
+
+Reorganize the code so that we can return final decision right away.
+This means that the two flags 'virtio' and 'virtioBusSuffix' need to be
+set prior to the return.

+Subject: [PATCH] qemuDeviceVideoGetModel: Remove logic for selecting 'virtio'
+ devices
+
+The virtio video device frontend type is either selected by the
+post-parse code based on capabilities or provided by the user/existing
+XML explicitly. No need to try to come up with a model when generating
+commandline based on broken logic.
+
+The difference in test output shows:
+ - honours user's config in case of the new 'device' attribute
+ - shows how incorrect fallback would be used for 'virtio-vga-gl'
+   (picked virtio-vga (non-gl) instead of 'virtio-gpu-gl')

+Subject: [PATCH] qemuValidateDomainDeviceDefVideo: Fix checks of virtio video
+ devices
+
+The currently existing checks are broken:
+ - only QEMU_CAPS_DEVICE_VHOST_USER_GPU is checked for vhostuser
+   backends (vhost-user-vga is actually separately packaged)
+ - the check for the 3d accelerated (-gl) versions checks only if one
+   of them exists (the commandline formatter picks a non-gl afterwards)
+ - 'virtio-vga'/'virtio-gpu' is not checked at all
+
+The code also doesn't yet check if, when the user passes the new
+'device' property manually the config actually makes sense.
+
+To fix all of the above introduce a table of supported frontend devices
+as well as properties that need to be checked for them.
+
+This requires fixing a recently-introduced test case which shows a
+nonsensical situation.

+Subject: [PATCH] qemuxmlconftest: Add invocation of 'video-virtio-vga-gpu-gl'
+ with missing caps and VIR_DOMAIN_DEF_PARSE_ABI_UPDATE
+
+Similarly to previous patch add testing of 'virtio-gpu-gl' or
+'virtio-vga-gl' with missing the respective capabilities, but this time
+allowing VIR_DOMAIN_DEF_PARSE_ABI_UPDATE.
+
+This will later on show that in case when the fallback can't be honoured
+the code will not pick a device that doesn't support acceleration (the
+non-gl variant).

+Subject: [PATCH] qemuxmlconftest: Add test cases for configs asking for
+ 'virtio-gpu-gl' or 'virtio-vga-gl' without the capability
+
+The capability check in 'qemuValidateDomainDeviceDefVideo' which
+validates whether a <video> definition with acceleration enabled is
+possible is only aggregate, thus validates that any '-gl' video backend
+is available.
+
+Since qemu compiles each backend into a separate module it's possible to
+have an installation where 'virtio-gpu-pci-gl' exist but 'virtio-vga-gl'
+doesn't and it will not be rejected at validation. The commandline
+though will generate a device *without* the '-gl' which is ABI
+incompatible with the counterpart which does have '-gl', but the VM
+starts. If such a VM is then migrated to a deployment which does have
+the '-gl' variant available, migration will fail because qemu will
+generate the '-gl' device as we don't record this fact in the XML.
+
+This test case captures this situation which will be fixed later.

+ QEMU_CAPS_DEVICE_VIRTIO_VGA disabled
+
+The test case shows that if the 'QEMU_CAPS_DEVICE_VIRTIO_VGA' capability
+is not present (e.g. if the corresponding qemu module isn't installed)
+libvirt will pick:
+
+  -device '{"driver":"virtio-gpu-pci", ...
+
+instead of:
+
+  -device '{"driver":"virtio-vga", ...
+
+but without any discernable difference in the XML.

+Subject: [PATCH] virQEMUCapsCacheLookupDefault: Fix error message when no
+ emulators are installed
+
+When querying capabilities for the default emulator with no other
+arguments (e.g. 'virsh domcapabilities) fix error whithout emulator
+installed an error is reported but the error would mention '(null)'
+architecture:
+
+  # virsh domcapabilities
+  error: failed to get emulator capabilities
+  error: unsupported configuration: unable to find any emulator to serve '(null)' architecture
+
+This happens as the error formatting takes 'archStr' which is NULL for
+the default architecture instead of using 'arch' which is populated by
+the host's architecture and converting it back.
