Andrei, It's good to test the RCs, that way anyone can report problems so they don't end up in the stable release. I am using KVM, alas am using local storage and never test for live migrations ...
Is there any more information you can share? ACS/libvirt/qemu logs etc. Lucian -- Sent from the Delta quadrant using Borg technology!
