kvm fds do not support fork().  Nothing prevents you from stopping the 
guest, reading guest state, fork()ing, and creating a new VM in the 
child with the same state, then restarting both instances.

qemu in general cannot be forked; the two instances would trample on 
each others disk images, host network connections (i.e. vnc, X, the 
monitor), guest network connections, etc.
