Shriram reported that he successfully tested these changes.

The revert of c/s 19444 simply removes more 'drbd' cruft from xend
internals.

As for my xend patch, is the commit message that vague?

-------------------------
xend: improve psudeo-bootloader support for external block scripts

Userspace tools support external block scripts (e.g. block-drbd
provided by drbd project). The psuedo-bootloader setup code in
xend has a few limitations wrt external block scripts, which this
patch addresses.

blkif.py: parse_uname() utility function should be able to parse a
disk specifier understood by the rest of the tools.

XendDomainInfo.py: Block devices using external block scripts must
be attached to dom0 before running the psuedo-bootloader.
-------------------------

I can improve it if need be.
