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., guests configured without <vendor> element can be freely migrated.
