Aiee - what's the plan? Can a running KVM be forked, as in into two separate processes to run the forked guests in parallel, or not?
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.
