Re: [libvirt-users] Hotplug of disk devices in LXC failed with libvirt of version 1.0.2
Hi, Gao Feng
I've tried what you said, but still exists the problem:
ubuntu@lxc:~$ vir attach-disk instance-0000002c /dev/dm-0 sdb
error: Failed to attach disk
error: Unable to create device /proc/10366/root/dev/sdb: Permission denied
I think finding what it means by saying 'Unable to create device
/proc/10366/root/dev/sdb: Permission denied' is the key.
But anyway, thanks for your help!

You should use attach-disk not attach-device.
vir attach-disk instance-0000002c /dev/dm-0 sdb
