Sorry, can you expand on this a bit? Are you saying that on SuSE, if you specify "vdev=xvda" in your config file, that you'll get PV devices named "/dev/xvda", but that if you specify "vdev=hda", that you'll get PV devices but named "/dev/hda"? -George _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
