Comment 5 tingting zheng 2014-04-14 09:36:13 UTC

Tested pass with:
libvirt-0.10.2-32.el6.x86_64

Steps:
1.Prepare a guest,set the Display as "Spice" and Video as "QXL".
2.Boot the guest.
3.Use virsh dumpxml to get the xml of the guest.
# virsh dumpxml mig > mig.xml

4.Change the ram value of video:eg:change ram from '65536' to '65535'
change xml from:
      <model type='qxl' ram='65536' vram='65536' heads='1'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>
to:
      <model type='qxl' ram='65535' vram='65536' heads='1'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/>
    </video>

5.Do migrate,error shows:
# virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml
error: unsupported configuration: Target video card ram 65535 does not match source 65536

Refer to the above comments,move the bug to VERIFIED.
