This is a re-send of previous patches:

http://lists.xensource.com/archives/html/xen-devel/2007-06/msg01021.html

The only change is that it explicitly looks for the driver type in xenstore
rather than assuming 'xvd' == 'tap' - this is because tap could be configured
with 'hd' or 'sd' nodenames too, and we still need to strip the leading
':aio' or ':vmdk', etc prefix from the path.

There are two patches:

  - xen-revert-phantom-2.patch  removes the phantom device code since it
    doesn't work & is redundant if QEMU can process tap devices straight
    from xenstore

  - xen-qemu-blktap-2.patch makes QEMU able to handle disks with xvd prefix
    treating them as IDE. Also makes QEMU strip the driver type prefix from
    tap disks since it can auto-guess driver
