By specifying <vendor> element in CPU requirements a guest can be restricted to run only on CPUs by a given vendor. Host CPU vendor is also specified in capabilities XML.
The vendor is checked when migrating a guest but it's not forced, i.e., a guest configured without <vendor> element can be freely migrated. ---
Sorry for such a big patch but the bulk of it is in cpu/ which is not so easy to be splitted reasonably.

Thanks, I updated the documentation to state <vendor> is supported since 0.8.3 instead of 0.8.2 and pushed. Jirka
