Sounds like expected behaviour to me; because the kvm in 6.4 is 
different in significant ways it's very problematic to resume. I would 
imagine live migration between the previous version in 6.3 and the one 
in 6.4 will also not work. This is not something new; this kind of stuff 
requires the exact same version of KVM when playing with the guest's 
This is all very IMHO and AFAIK.
