ovf file in export domain
It is possible that libguestfs-1.28.1-1.40.el7 will fix this, as a side-effect of fixing bug 1234351. For esx windows guest,after convert to libvirt,the xml shows it's graphics driver is cirrus:
<graphics type='vnc' port='-1' autoport='yes'/>
<video>
<model type='cirrus' vram='16384' heads='1'/>
<address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
</video>
But check in guests,the graphics driver is "Standard VGA Graphics Adapter" under "Display adapters".
There are several things going on here: - Virt-v2v < libguestfs-1.28.1-1.40.el7 only copied the virtio-blk and virtio-net drivers into the guest. (In >= -1.40.el7, it now copies all the drivers into the guest, including QXL ones if available). - There are no QXL drivers for Windows 2003. - When converting Windows guests, virt-v2v used to return gcaps_video == Cirrus, whether or not it had installed a QXL driver. (Fixed in: 08bfad986a4288defd4b994f8f2c74da3193e3a2) - The -o rhev/-o vdsm modes ignored gcaps_video anyway, and just supplies a QXL driver to the guest. (See bug 1213701 and bug 1211231) - -o libvirt uses gcaps_video correctly, explaining comment 4. - But in any case, QXL can deliver basic SVGA video, so none of this really matters for basic guest functionality (ie. can it display something on the screen). It does matter if we want to provide the best quality display to the guest. I believe this should now be fixed (in fact, in RHEL 7.3 too). Can we retest this with the final rebased RHEL 7.4 package. This bug could be reproduced when convert win7 win2008r2 guest : Related packages: virt-v2v-1.36.2-1.el7.x86_64 libguestfs-1.36.2-1.el7.x86_64 libvirt-3.1.0-2.el7.x86_64 qemu-kvm-rhev-2.8.0-6.el7.x86_64 libguestfs-winsupport-7.2-2.el7.x86_64 virtio-win-1.9.0-3.el7.noarch (In reply to kuwei from comment #9) > This bug could be reproduced when convert win7 win2008r2 guest : > > Related packages: > virt-v2v-1.36.2-1.el7.x86_64 > libguestfs-1.36.2-1.el7.x86_64 > libvirt-3.1.0-2.el7.x86_64 > qemu-kvm-rhev-2.8.0-6.el7.x86_64 > libguestfs-winsupport-7.2-2.el7.x86_64 > virtio-win-1.9.0-3.el7.noarch Can you please provide the virt-v2v log with -v -x? Verify it with below builds: virt-v2v-1.36.3-1.el7.x86_64 libguestfs-1.36.3-1.el7.x86_64 libvirt-3.1.0-2.el7.x86_64 virtio-win-1.9.0-3.el7.noarch Steps: Scenario 1 1:Prepare win7 and win2008r2 guests on esx serve 2:Use virt-v2v to convert the esx windows guest to rhv. 3:After conversion,import the guest to data domain. 4:Try to boot the windows guest,check "Display adapters" Result:QXL driver is installed,check "Display adapters",it shows as "Red Hat QXL GPU". Scenario 2: 1:Prepare win7 and win2008r2 guests on Xen serve 2:Use virt-v2v to convert the windows guest to rhv. 3:After conversion,import the guest to data domain. 4:Try to boot the windows guest,check "Display adapters" Result:QXL driver is installed,check "Display adapters",it shows as "Red Hat QXL GPU". Scenario 3: 1:Prepare win7 and win2008r2 guests on kvm local. 2:Use virt-v2v to convert the windows guest to rhv. 3:After conversion,import the guest to data domain. 4:Try to boot the windows guest,check "Display adapters" Result:QXL driver can't installed automatically in guest after converted by v2v . So,as above i think we can move the bug to verified ,and we track another bug 1356550 about the issue QXL can't installed automatically in guest after converted from kvm to rhv by v2v.

Created attachment 1040364 [details] Debug info Description: QXL driver is not installed for some version of windows guest after convert to RHEV Version: libguestfs-1.28.1-1.38.el7.x86_64 virt-v2v-1.28.1-1.38.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Prepare some windows guests on esx server. 2.Use virt-v2v to convert the esx windows guest to rhev. # virt-v2v -ic vpx://root.72.112/data/10.66.72.49/?no_verify=1 -o rhev -os 10.66.90.115:/vol/v2v_auto/nfs_export -b rhevm --password-file /tmp/passwd2 esx6.0-win2003-i386 -v -x 3.After conversion,import the guest to data domain. 4.Try to boot the windows guest,check "Display adapters",it shows as "Standard VGA Graphics Adapter". 5.Check the ovf file of the guest in export domain,it shows the "Graphics" as "qxl". <Item> <rasd:Caption>Graphical Controller</rasd:Caption> <rasd:InstanceId>5</rasd:InstanceId> <rasd:ResourceType>20</rasd:ResourceType> <rasd:VirtualQuantity>1</rasd:VirtualQuantity> <rasd:Device>qxl</rasd:Device> </Item> Actual results： As description. Expected results: QXL driver is installed,check "Display adapters",it shows as "Red Hat QXL GPU". Additional info: For windows 2003,win 2008 guest,it all shows "Standard VGA Graphics Adapter" under "Display adapters". For windows 2008r2,it shows "Red Hat QXL GPU" under "Display adapters".
