A troubleshooting experience with the thermal migration of an OpenStack virtual machine

First look at the CPU model, from the/proc/cpuinfo can be seen all the CPU model version is the same

You can see the error message via Nova live-migration--debug <instance-xxx> <node-xxxx> command Line migration

It's going to be libvirt.py.

Through this API, can not see the specific error message, may be related to the flags is 0.

The same CPU is not the same CPU features, Bright blind me!

Compared to the host CPU flags, really poor a monitor feature, Google may be a kernel bug.
