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
