The following patchset adds a driver for Intel's hardware
virtualization
extensions to the x86 architecture. The driver adds a character device
(/dev/kvm) that exposes the virtualization capabilities to
userspace. Using
this driver, a process can run a virtual machine (a "guest") in a fully
virtualized PC containing its own virtual hard disks, network
adapters, and
display.
Using this driver, one can start multiple virtual machines on a
host. Each
virtual machine is a process on the host; a virtual cpu is a thread
in that
process. kill(1), nice(1), top(1) work as expected.
Where is the user space for this? Is it free?
I have to go through the motions of creating a sourceforge project for
this and uploading it. And yes, it is free.
Don't even bother creating a project. Just submit the patches back to
QEMU. There's been a lot of discussion about this functionality within
QEMU. There's no reason to fork QEMU yet again (Xen has given up and is
now maintaining a patch queue). In this case, there's no reason why you
would even need a patch queue.

I suppose you need a device model. Do you use qemu's?
Yes. I can't imagine anyone doing that work from scratch (Xen also
uses qemu).
