blkback is used as block backend, if blkback is missing from your dom0
kernel, this configuration will fail.
A block device must be specified because blkback cannot handle files by
itself.
The format must be raw.

If you want backwards compatibility then phy:devname works in xm as well as phy:/dev/devname . Many of the example files in /etc/xen still use the earlier format.
