for 10.10 and 11.04, the -server kernel *may* provide you with what you
need. The -virtual first began as just the -server kernel with a subset of
modules, but then moved a bit away. I think they both install into the
same /lib/modules directory, and the drdb module might "just work".
Other than that, you'll have to basically re-build the kernel from the
-virtual config, but enable the drdb module. Might be some other way of
doing that also. The -extra package is a nice feature add for -virtual.
