Start VM with gdbstub 2. Pause VM via gdbstub 3. Save migration snapshot via HMP: `migrate "exec: gzip -c > foo.gz"` 4. Start new QEMU instance from snapshot by adding these args to whatever you used to launch QEMU: `-incoming "exec: gzip -c -d foo.gz"` Additional information: This can be fixed by adding `{ RUN_STATE_INMIGRATE, RUN_STATE_DEBUG },` to `runstate_transitions_def` in `softmmu/runstate.c`. It's not clear if there are any negative ramifications of this, but it seems to work for me?
