Old IDE drives are not SCSI either, but now they appear as 'sd' since a while. 'hd' or 'sd' or 'mmc' or 'xvd' are just names. They do not represent hardware as such. Otherwise the interface into the blocklayer to request major/minor/name would be like 'hey, I'm the IDE/SCSI/MMC/whatever driver, give me something'. Anyway, since this is now set in stone, any VM out there which still is configured to use /dev/hd* has to be adjusted to /dev/xvd* upfront when going from xenlinux to pvops.
