I use the following qmp commands (file cmds.txt) for testing:
--------- cmds.txt start--------
{"execute":"qmp_capabilities", "arguments":{}}
{"execute":"migrate", "arguments":{ "uri":"exec:cat >/dev/null"}}
{"execute":"query-migrate", "arguments":{}}
--------- cmds.txt end--------
and the following command line to start qemu:
# ./x86_64-softmmu/qemu-system-x86_64 -chardev
socket,id=qmp,path=/tmp/test.qmp,server,nowait -mon chardev=qmp,mode=control
--enable-kvm
I then execute the qmp commands with:
# cat cmds.txt | socat - /tmp/test.qmp
{"QMP": {"version": {"qemu": {"micro": 90, "minor": 2, "major": 1}, "package":
""}, "capabilities": []}}
{"return": {}}
{"return": {}}
{"timestamp": {"seconds": 1353587785, "microseconds": 134907}, "event": "STOP"}
{"return": {"status": "completed", "downtime": 8, "ram": {"total": 143065088,
"remaining": 0, "transferred": 772035, "duplicate": 34755, "dirty-pages-rate":
0, "normal-bytes": 737280, "normal": 180}}}
so far so good.
But if I execute that again I get an error:
# cat cmds.txt | socat - /tmp/test.qmp
{"error": {"class": "CommandNotFound", "desc": "The command qmp_capabilities
has not been found"}}
{"return": {}}
{"return": {"expected-downtime": 0, "status": "active", "total-time": 33,
"ram": {"total": 143065088, "remaining": 8937472, "transferred": 495481,
"duplicate": 67388, "dirty-pages-rate": 0, "normal-bytes": 1200128, "normal":
293}}}
The interesting thing is that it works perfectly without --enable-kvm.
Can somebody reproduce that?
