2. Continue VM: \
{"execute": "cont"} \
3. Check disk info before hot unplug: \
(guest)#ls /dev/[vhs]d* | grep -v [0-9]$ \
4. Unplug device from vm: \
{"execute": "device_del", "arguments": {"id": "stg1"}} \
{"timestamp": {"seconds": 1704360854, "microseconds": 751289}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/stg1/virtio-backend"}} \
{"timestamp": {"seconds": 1704360854, "microseconds": 752078}, "event": "DEVICE_DELETED", "data": {"device": "stg1", "path": "/machine/peripheral/stg1"}} \
5. Check device info via "info qtree": \
{"execute": "human-monitor-command", "arguments": {"command-line": "info qtree"}} \
Actual Result: \
After step5, qemu core dump with info: \
qemu-system-x86_64: ../qapi/string-output-visitor.c:316: start_list: Assertion `sov->list_mode == LM_NONE' failed. \
