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.

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).
