[Xen-devel] Migration and CPU type?

[John Byrne <john.l.byrne@xxxxxx>]

There are various differences between x86 CPU types that I believe would 
cause a guest to fail after being migrated. Are there checks in the 
migration code to prevent this from happening? Does it check for an 
"incompatible CPU" and fail early, leaving the guest running on the 
source host? If there is a check, what is its nature? (Exact match of 
CPU type/rev or something based on CPU-features?)
Thanks,

John Byrne
