I've noticed that live migration stopped working for me on OVZ 7 as well.
It used to work. heck, even in openvz 6 it worked.
I posted here after noticing the issue, and was advised that live migration
between intel and amd CPUs was problematic. So yesterday I bit the bullet,
and swapped my OVZ amd host for a genuine intel box. Sadly, even with intel
on both OVZ hosts, live migrate always fails. It still claims cpu mismatch,
and so I pass -f cpu, but it still crashes and burns. Dead migration still
works though.
Although both nodes are now running Intel, the CPUs are not identical. Is
this an issue?
Here are the CPUs on each node:
