Hi Hoot

 

Just cat /proc/cpuinfo to find  pae and vmx flags for Intel CPU, if you use the AMD CPU please to find pae and svm flags, However, the most modern processor all support it.

主题： [Xen-users] 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?

Thanks,

Joe
