[libvirt] Support to transfer OVSDB:Interface stats during Live Migration

Hi, I was experimenting 'live migration' with libvirt (using virsh) and observed that post migration the Interface stats in 'OVSDB:Interface' table are not transferred. Only the values in 'external_ids' column seem to be synced up. The libvirt version I'm using is 0.9.11.3. The virsh command used for migration is: 'virsh migrate --live fc17-vm qemu+ssh:// 10.23.167.219/system' Is this the right behavior (or) Have I missed out on some option? Can some one please guide on the approach and the source files to look at If i need to add this support? thanks Kiran
