Hi Daniel,
I noticed that the patch "Add support for hotplug/unplug of disk devices in
LXC" you wrote had been merged into libvirt of version 1.0.2.
But when I used this function, it report an error with details as following:
ubuntu@lxc:~$ vir attach-device instance-0000002c disk.xml --config
error: Failed to attach device from disk.xml
error: Unable to create device /proc/18377/root/dev/sdb: Permission denied
ubuntu@lxc:~$ vir attach-device instance-0000002c disk.xml
error: Failed to attach device from disk.xml
error: Unable to create device /proc/18377/root/dev/sdb: Permission denied
ubuntu@lxc:~$ cat disk.xml
<disk type='block' device='disk'>
<driver type='raw' cache='none'/>
<source dev='/dev/dm-0'/>
<target dev='sdb' bus='scsi'/>
</disk>
You should use attach-disk not attach-device.
vir attach-disk instance-0000002c /dev/dm-0 sdb
Thanks
