In theory yes. There would need to be a bit of work to disassociate it
from kvm, but nothing too difficult.

Note that the kvm x86 emulator is more general than need be (emulates
real mode code and cpl 0 instructions) and less general than needed
(many instructions are not emulated, for example nopl).
