How to enable virtualization?

[Christoph Doerbeck]

AFAIK, KVM is also in FC7 which is in beta now if I'm not mistaken.

Just to clarify, VMWARE is going to support "full" virtualization which
will utilize VTx (Intel x86) or SVx (AMD).  So considering full-virt,
the second generation of hardware assisted virt technologies should
greatly increase speed and also likely enable live migration type
operations which xen cannot do (full virt).

Considering para-virt, performance trump vmware and live migration works
like a charm (as demo'd at the March BLU meeting).

The kernel flags (if you cat /proc/cpuinfo) that you are looking for are
'vmx' (on Intel) and svm (on AMD)
