Guest display problems after *virt-v2v* conversion have been fixed
Previously, the video card driver setting of a guest converted with the *virt-v2v* utility was ignored, causing various display problems in the guest. This update ensures that *virt-v2v* generates the libvirt XML file for the converted guest properly. As a result, the video card setting is preserved, and the guest can take full advantage of graphical capabilities after the conversion.

Debug log
I found the same thing during my own testing. It's a bug, and a regression over the old virt-v2v which used to install xorg-x11-drv-qxl in the guest during conversion. This should be fixed with https://github.com/libguestfs/libguestfs/commit/f56031d5493af36e46de7a97f150a8724b6007fa which is in libguestfs >= 1.31.20. So it should be fixed by the rebase (bug #1218766). tingting: the result now is that any RHEL guest has QXL as video card set in libvirt. (In reply to Pino Toscano from comment #5) > This should be fixed with > https://github.com/libguestfs/libguestfs/commit/ > f56031d5493af36e46de7a97f150a8724b6007fa > which is in libguestfs >= 1.31.20. > > So it should be fixed by the rebase (bug #1218766). > > tingting: the result now is that any RHEL guest has QXL as video card set in > libvirt. Hi,Pino Do you mean that no matter the original guest has graphics/video as vnc+cirrus or spice+qxl,after converted to libvirt,it all becomes spice+qxl?

No, the change is only about cirrus vs. qxl. vnc or spice is left as it is. So vnc+cirrus will be vnc+qxl, and spice+qxl will stay as it is (as it's qxl already). I tested the with (vnc+cirrus) and it's converted to vnc+qxl successfully. And then tested it with spice+cirrus, it changed to vnc+qxl instead of spice+qxl unexpectedly.
Before converting (spice+cirrus):
# virsh dumpxml rhel7.2-10301 | grep graphic -A5
<graphics type='spice' autoport='yes' listen='0.0.0.0'>
<listen type='address' address='0.0.0.0'/>
</graphics>
<sound model='ich6'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
<video>
<model type='cirrus' vram='16384' heads='1'/>
After converting (vnc+qxl):
# virsh dumpxml aaa | grep graphic -A5
<graphics type='vnc' port='-1' autoport='yes' listen='0.0.0.0'>
<listen type='address' address='0.0.0.0'/>
</graphics>
<sound model='ich6'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/>
</sound>
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>
I created bug 1312254 for this issue described in comment 10. Verify the bug with builds:
virt-v2v-1.32.3-1.el7.x86_64
libguestfs-1.32.3-1.el7.x86_64
Steps:
Scenario1
1 Prepare a guest with spice+cirrus mode on libvirt
# virsh dumpxml xen-fv-rhel6.6-x86_64
<graphics type='spice' autoport='yes' keymap='en-us'/>
<video>
<model type='cirrus' vram='65536' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
2 Using virt-v2v to convert the guest
# virt-v2v xen-fv-rhel6.6-x86_64 -on spice-cirrus
[ 0.0] Opening the source -i libvirt xen-fv-rhel6.6-x86_64
[ 0.0] Creating an overlay to protect the source from being modified

[ 178.9] Finishing off
3 Check display mode in guest spice-cirrus xml after converting by virt-v2v
#virsh dumpxml spice-cirrus
<graphics type='spice' port='5902' autoport='yes' listen='127.0.0.1' keymap='en-us'>
<listen type='address' address='127.0.0.1'/>
</graphics>
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>
<alias name='video0'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
Result now:
guest display with spice+cirrus mode could be converted to spice+qxl successfully
Scenario2
1 Prepare a rhel5 guest with vnc graphics on xen server.
# virsh dumpxml xen-hvm-rhel5.11-i386
<graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
2.Use virt-v2v to convert the guest to libvirt.

3 Check the guest xml of graphics part,it's vnc with qxl model.
# virsh dumpxml xen-hvm-rhel5.11-i386
<graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/>
<video>
<model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1'/>

</video>
Additional info:
Guest with vnc+cirrus mode and could be converted to vnc+qxl successfully
Result:
guest display with vnc mode and will be converted to vnc+qxl mode, but according to https://bugzilla.redhat.com/show_bug.cgi?id=1300250#c10 and https://bugzilla.redhat.com/show_bug.cgi?id=707055#c2, display:vnc + qxl mode is not supported. Hi,rjones, could you help to see this?
Note comment 12 refers to bug 1312254. I have replied on that bug. I can reproduce it with: libguestfs-1.31.7-1.el7.x86_64 virt-v2v-1.31.7-1.el7.x86_64 Reproduce steps: 1.Prepare a rhel5 guest with vnc graphics on xen server. virsh dumpxml xen-hvm-rhel5.11-i386 <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> 2,Convert it to kvm using the virt-v2v virt-v2v -ic xen+ssh://10.73.3.21 -of raw xen-hvm-rhel5.11-i386 -os default There is no any error appear on the command line , convert successfully 3, Check the guest xml of graphics part,it's vnc with cirrus model. 4,Finally, try to boot the guest,it fails to start X server. Testing with: libguestfs-1.32.3-1.el7.x86_64 virt-v2v-1.32.3-1.el7.x86_64 The steps are same with reproduce steps 1,after step3.Check the xml file after convert it #virsh dumpxml xen-hvm-rhel5.11-i386 <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <video> <model type='qxl' ram='65536' vram='65536' vgamem='16384' heads='1' primary='yes'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> 2,step4:can boot the guest to X server normally Refer to the above comments,the bug has been fixed,so move the bug to VERIFIED.

Expected results: Cirrus driver is installed and X server can be launched successfully. Additional info: 1.For rhel6 and rhel7 guest,correct driver(cirrus driver) is installed for guest with vnc graphics after conversion to libvirt.
