Load the suspend vm.out by  # qemu-kvm .... incoming fd</tmp/vm.out,
and execute monitor cmd to reboot  # system_reset.
Then re-dump VM to disk by (qemu) migrate -d exec:cat>/tmp/vm.out2

Is it satisfied for you?

(qemu) info migrate

info commands(for hmp) always correspond with query commands(for qmp),
some query-cmds are not implemented right now (eg. query-network)


hmp            qmp
---            ---
info status -> query-status
info block  -> query-block
info pci    -> query-pci
....
