Ah, well, it's already implemented :) (though not hdXY/sdXY, but hdXsY/sdXsY/xvdXsY, the Mach naming scheme)

the good point in it is that it helps using the same image between native execution and virtualization.

Don't try to support hdXY and sdXY for disk devices. This support is special to the old Xen-Linux implementation and will not survive the upstream integration.

Note: Keir just drop non-PAE support in the 3.3 branch, so we are stuck
with 3.0-3.2 until we implement PAE

In addition to the list: supporting partitions: in the configuration
file, one can say "hda1" instead of "hda", which means that we are
supposed to create an hd0s1 device instead of just hd0. This is done by
interpreting the vbd number as follows:

  202 << 8 | disk << 4 | partition      xvd, disks and partitions up to 15
    8 << 8 | disk << 4 | partition      sd, disks and partitions up to 15
    3 << 8 | disk << 6 | partition      hd, disks 0..3, partitions 1..63

i.e. hda1 gets number 769.

Support for more than 15 disks is not decided yet, will maybe just look
like

  1 << 28 | disk << 8 | partition       xvd, disks or partitions 16 onwards

Note: for the grant table to work, libxc would have to talk with a privileged server which would be responsible for managing grant table entries.

Actually the current libxc interface is not yet furnished enough for building user-level device drivers. That is on the TODO list of Cambridge Uni people.

- port libxc
-> possibly write user-level drivers
