I installed SL 6.0 on one of my machines, and indeed it provides KVM
(Description in French):
# yum groupinfo virtualization
Loaded plugins: refresh-packagekit
Setting up Group Process
epel/group_gz

Group: Virtualisation
Description: Fournit un environnement afin d'héberger des clients
virtuels.
Mandatory Packages:
qemu-kvm
Optional Packages:
qemu-kvm-tools
I think CentOS will do the same for 6.0.

You can assign multiple VMs to one CPU. For example, you can have a
hostmachine with dual-CPUs quadcore, and have 15 VMs or more installed
on it, and some of them assigned with two cores or more. It is only more
threads on a core.
