but didn't update the ABI check.

git describe: v1.2.0-63-g952ab4c
Downstream patch posted:
http://post-office.corp.redhat.com/archives/rhvirt-patches/2013-December/msg00097.html
Tested PASS with:
libvirt-1.1.1-14.el7.x86_64
If I 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>
Error will show when migrating with the updated xml file:
# virsh migrate --live mig qemu+ssh://10.66.5.7/system --xml mig.xml
error: unsupported configuration: Target video card ram 65535 does not match source 65536

Description Stable guest ABI doesn't check ram value of video Version: libvirt-1.1.1-13.el7.x86_64 How reproducible: 100% Steps to Reproduce: 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,no error shows. # virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml 6.If I change vram value from xml,there is error. # virsh migrate --live mig qemu+ssh://$ip/system --xml mig.xml error: unsupported configuration: Target video card vram 65535 does not match source 65536 Actual results： As step 5 describes. Expected results: Error shows when ram value in xml is set different with guest. eg:error: unsupported configuration: Target video card ram 65535 does not match source 65536
