Hi Christian,
Thank you for reply !
Could I ask a version of libvirt which is your patch applied ?
I'm trying it with libvirt0.9.8-2ubuntu9, but there is same error.
(I'm using blow package:

libvirt 0.9.9 fixes this (the applied patch is
http://www.redhat.com/archives/libvir-list/2011-December/msg00506.html
if you're curious).
2012/2/6 Christian Brunner<christian@xxxxxxxxxxxxxx>:
Libvirt is trying to set security lables even for network shares. This
will not work. I think this is fixed in newer libvirt versions. For
older versions you can try this patch:
http://www.redhat.com/archives/libvir-list/2011-May/msg01446.html

Hi, all.
I'm trying to attach rbd volume from instance on KVM.
But I have problem.
Could you help me ?
