  • Thread-topic: CPU Prerequisites for Live Migrations

Hi all,

I'm trying to find documentation to describe what specific CPU flags, models, 
families requirements are needed for live migrations to be "supported."  I have 
found mailing list archives which tend to say things like "should" work or 
"may" work, but nothing that says "is supported." or "is certified."

Basically what I'm wondering is that if I have (2) quad-core cpu's on one 
server and (2) quad-core cpu's on another server -- both have the same family 
and stepping and exact same flags.  The only difference is that the model is 
different.  Is that something that the xen hypervisor typically will support 
when it comes to live migration?
