Ring0 support is needed any way, even if userspace applications are used
to drive it.

KVM was not designed to be portable, so I guess it would just be easier
to start from scratch.

Note, however, that for the emulation of devices, the same approach as
KVM/Xen can be used, i.e. running a user-space qemu.
