This article starts you up on the topic in a somewhat odd fashion.

The idea is that qemu is my idea of virtualization. I have never got
vmware or xen working.
Instead qemu gives me what I want without any pain at all. Only a
learning curve which you cannot avoid
anyway.
qemu works like magic since I bought a cookie box PC from Delta a
year ago and I can run qemu without a hitch on it.
The shopkeeper Kamal tells me: "Sir, this PC is for jewellery shops
billing counters. It is not powerful."
"Is that so? I will purchase it since there is a DVD writer in it."
It is an Asus Mini PC.
I can run many instances of qemu in it without hardware acceleration
with KVM or whatever.
Of course there is no KVM on OpenBSD.
But I can run linux or OpenBSD or any OS as guest on qemu.
And I can bridge multiple qemu instances for full networking with
linux bridging or OpenBSD bridging.
In other words you can run any host with qemu and connect multiple
guests either running off qemu filestores that behave
like hard disks or liveCDs or just about any ISO image or even USB sticks.
It will take some time to learn all the possibilities it affords but
then you can get many benefits of virutalization with it.
It is an emulator and not a virtualization environment.
But I don't like to do hair splitting.
It give us the ability to run multiple machines without multiple power
chords and multiple ethernet connections.
Each machine instance is ideally a qemu filestore created with:
$ qemu-img create filestore.hd0 2G
filestore.hd0 is the name of the file of size 2 Gigs.
