So if I understand what you're saying: best not to use kvm guests for build
servers with pre-Nehalem processors.

pre-Nehalem / pre-Barcelona, > 4 vcpus, yes.

How about 2 vcpus, and how about AMD processors ?

2 vcpus (or 4) should be fine. AMD processors (Barcelona+) would be good for any number of vcpus.

Hmm.. that's sorta good (not so good for owners of most
Intel CPUs -- Nehalem just started its life).  But still
confusing.  Namely, 2..4 vcpus per GUEST or HOST -- for
the ore-Nehalem ones? :)

Thanks!
