Is there a possibility to live-migrate between different CPUs without downtime?

Hi there,

I have some mixed compute nodes inside a OpenStack Kilo platform. Unfortunately I missed to set cpu_mode = none in nova.conf.

Is there any possibility or dirty hack to migrate running instances to another KVM with other CPU flags or just with a set cpu_mode = none without shutting the compute node or the instances down?

cheers, hauke
