Hello,
I am trying to add a block device dynamically using qmp and are having some
issues.
After successfully adding the block device using "blockdev-add" and verifying
that it has been added using "query-block", I am unable to see the block device
in the VM under /dev/sdXX
I am using ubuntu14.04LTS: qmp version:
{"QMP": {"version": {"qemu": {"micro": 0, "minor": 0, "major": 2}, "package": "
(Debian 2.0.0+dfsg-2ubuntu1.2)"}, "capabilities": []}}
Here's what I am doing:
1. /usr/bin/kvm-spice -hda kvmimages/ubuntu.image -m 768 -usbdevice tablet
-vnc :5 -qmp tcp:localhost:4444,server,nowait
2. telnet localhost 4444
3. In the telnet session run:
{"execute":"qmp_capabilities"}
{"return": {}}
{ "execute": "blockdev-add",
"arguments": { "options" : {
"id": "disk1",
"driver": "qcow2",
"file": { "driver": "file",
"filename": "testvm.qc2" } } } }
{"return": {}}
{ "execute": "query-block" }
4. query-block returns the device "disk1", but when I check the vm:
# vncviewer :5
there are no new devices.
I thought that maybe it is a hotplug SATA bug detailed here:
http://ubuntuforums.org/showthread.php?t=1998055
but running:
#rescan-scsi-bus resulted in no new block devices.
Thanks for any help!
Ken
