| Doc Text: |
Previously, single QXL PCI was set `true` only on VM creation when the OS type set to linux type. Now, the single QXL PCI will be set once the OS set and changed, allowing it being `true` for linux type VMs and `false` otherwise.

*** Bug 1912679 has been marked as a duplicate of this bug. *** ovirt-engine-api-model was not yet built including the fix "depracate single qxl pci", moving back to Modified I don't mind pushing this to the next build, but the api part is not really needed for verification - had the QE's environment used latest ovirt-engine, this could have been verified. Verified:
ovirt-engine-4.4.5.3-0.14.el8ev
vdsm-4.40.50.3-1.el8ev.x86_64
qemu-kvm-5.1.0-14.module+el8.3.0+8790+80f9c6d8.1.x86_64
libvirt-daemon-6.6.0-7.3.module+el8.3.0+9547+7d548490.x86_64
how to test:
When single-PCI is disabled (non Linux OS type), in VM dumpxml, the number of QXL devices is equal to the monitors value set in edit VM dialog (1,2 or 4) and heads='1' for each QXL device.
For example:
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='32768' heads='1' primary='yes'/>
<alias name='ua-6dd1c5a9-eb1b-44d4-8101-f98852d02368'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
</video>
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='32768' heads='1'/>
<alias name='ua-caceb0e2-a910-4732-bd0c-4c4511b19cb7'/>
<address type='pci' domain='0x0000' bus='0x12' slot='0x02' function='0x0'/>
</video>
When single-PCI is enabled (Linux OS type), in VM dumpxml, there is one QXL device and heads is equal to monitors value.
for example:
<video>
<model type='qxl' ram='262144' vram='131072' vgamem='65536' heads='4' primary='yes'/>
<alias name='ua-cc5a5aa5-b40a-407b-aecd-9a674b7de97a'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
</video>
verification procedure:
1. Set VM OS type to RHEL8 VM, in console tab select QXL, Spice and 4 monitors.
2. run VM.
3. Observe VM dumpxml and verify there is only one QXL device and heads='4'
4. Open VM console, verify only 1 monitor can be viewed. click on virt-viewer -> View -> verify it is possible to select other displays out of 4 and each display can be opened.
5. Power off VM, set OS type to Windows 10 and run VM.
6. Observe VM dumpxml and verify there are 4 QXL devices, each one with heads='1'
7. Open VM console and verify all 4 displays are opened and each one is showing VM display.
8. Repeat steps 1-7 for all available OS types.
