Hey all,

I'm trying to get a storage domain up and running in Xen 4.4. I'm currently
using Ubuntu 14.04 for the dom0, storage domain and guest. I'm currently
following the steps here,
http://wiki.xenproject.org/wiki/Storage_driver_domains, but am not having
any luck.

*I received this dmesg error on the guest during start-up:*
xenbus_probe_frontend: Timeout connecting to device: device/vbd/51715
(local state 3, remote state 2)

This means the guest (in state 3) is initialised and waiting for a
connection from a peer, and the storage-domain (in state 2) is finished
with the early initialisation but is waiting for information from the peer
or hot-plug scripts. This would imply to me that there is a communication
error between the xen-blkfront and xen-blkback drivers or an error in the
scripts.

*However, on the storage-domain I receive this dmesg:*
[ 2987.170473] xen-blkback: event-channel 19
[ 2987.170761] xen-blkback: /local/domain/3/device/vbd/51715:using single
page: ring-ref 10
[ 2987.171319] xen-blkback: ring-pages:1, event-channel 19, protocol 1
(x86_64-abi) persistent grants

Is this the information that the xen-blkback driver is waiting for? If so,
why does it not continue through the initialisation process? If not, what
information is the xen-blkback driver waiting for, and how do I ensure the
front-end and back-end drivers will establish a connection?

I've attached the output of xenstore-ls and the dmesg outputs of the guest
and storage domain.

Thanks in advanced,
Paul Mogren
