In some cases, but not all. The natural case is to install CentOS 5.2,
with the Virtualization group, and run virt-manager, which sets pygrub
in the resulting config. Editing a xen config created by virt-manager,
and setting it to use the drbd backend as documented, results in a big
fat error.

No. The error is "Error: Disk isn't accessible" either way.
The problem, as Florian points out, is with pygrub.

The point I'm trying to make is that the DRBD chapter on Xen can
potentially waste the time of a new CentOS admin using it. Yes, I
agree that pygrub (and virt-manger) code needs fixing, and enhancing
(respectively), but that's a development issue. This is a simple
documentation fix.
