On the Q&A system on XenProject.org, Philipp asks:

"I have a XEN-Server with an XEON E3-1220V3 and would like to add a new
server with an XEON E3-1230LV3. AFAIK the only difference between these 2 CPUs
is the hyperthreading feature. Does anyone know if a live migration would work
between these 2 CPUs? I don't want to get into feature masks since it
doesn't seem to be worth the effort."

If you have information, please reply here:

Or reply to me and I will post it to the Q&A system.

Thanks,
