Please note that this issue has been fixed in qemu 1.3 and a patch has been sent also for RHEL here: https://bugzilla.redhat.com/show_bug.cgi?id=869981

Hi Vinzenz, thanks for the report and link to the commit. I verified that the referenced commit does fix migration from f17 to f18.

However it breaks migration from pre-patch f18 to post-patch f18, which is a common case for people that use libvirt to save VMs on shutdown. I've posted upstream about it:

Comment 3 Cole Robinson 2013-04-01 12:26:50 UTC

This is 'fixed' in rawhide, but that patch needs to be adapted to work on F18 as well:
