QEMU more-or-less has KVM built into it since about version 0.10.
Wikipedia has a lot of articles about virtualization, so I would go
there for more.
Go with Virtualbox unless you have some special need.
Hi. I think you misunderstood my question. I'm trying to switch from xen to
kvm, because xen just doesn't work on that particular server. QEMU provides
emulation for IO and uses KVM for memory/cpu virtualization. In Debian
Squeeze, there are two packages for qemu, one named qemu, the other qemu-kvm.
Both are based on version 0.11.1 of qemu and both supposedly support kvm.
My question is, why there are two apparently identical qemu packages. Which
one should I use with kvm.
thanks
