Which dom0 kernel is this? Assuming 2.6.32 (squeeze) based do you have
the xen-blkback/blktap modules (and any other backend modules) loaded?

What udev rules do you have? What is present in /etc/xen/scripts?

There's usually a logfile called xen-hotplug or something along those
lines -- does that show anything?

Does xenstore-ls show the backends under /local/domain/0/backend and the
frontends under /local/domain/<domid>/device?

Did this work previously on this machine (i.e. is this an new issue
after an upgrade or a fresh install etc).

May or may not relate to this issue (probably not) but I'd normally
recommend not using network-script at all and rather configuring
your /etc/network/interfaces as per
