[Jean-Laurent Ivars]

hello

maybe just a silly idea, but did you tried to ssh from host1 -> Host2 maybe it’s just a knowhost issue…

regards

> 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.
