It wasn't clear to me exactly what was in your HVM DOMU config file that
didn't work, but in all cases that I have seen that were simular it was
caused by a mistake on my part where I put the wrong device in the
config file.  I believe that the "dsk" device must be used in a Xen
config to access a zvol for the purposes of presenting it to the guest.
That is, make sure that you use the block device and not the character
device.  The same is true of LVM and all other storage types, I believe.
