Hi all,

After loading nbd module in compute node, I continued trying to boot from a
bootable cinder volume but this is what I see in nova-compute.log.

I checked in the archive and I found that this bug (1126348) has been fixed
in grizzly 2013.1 which I am running.

Thanks for your help.
Amine.

Command: sudo nova-rootwrap /etc/nova/rootwrap.conf qemu-nbd -c /dev/nbd9
/var/lib/nova/instances/933d4f37-ce12-4ac8-abc7-d248295375a4/disk
Exit code: 1
Stdout: ''
Stderr: "qemu-nbd: Failed to bdrv_open
'/var/lib/nova/instances/933d4f37-ce12-4ac8-abc7-d248295375a4/disk': No
such file or directory\n")
