I'm trying a live Migration via NFS-Storage with a KVM. Migration from Host 2 -> Host 1 always works, Migration from Host 1 -> Host 2 seems to work (no error in live-migration output) but the KVM hangs after migration. I can't ping the VM and VNC output is frozen.


Tried it several times, always with the same result. The only difference between the two hosts are the CPUs:


Host 1:

AMD Opteron(tm) Processor 4234


Host 2:

AMD Opteron(tm) Processor 4184



Howerver, the KVM is set do Default CPU (KVM 64).


How can that happen?


Thanks

Greets,

Kilian
