There are (at least) two ways to allocate disk space to a VM under Xen.
The easiest way is to use a file-backed VBD, in which case you can store the 
disk image on any file system, including one that lives on a DRBD device.  
Once you have DRBD running, you don't have to do anything special to do this. 
See sec 6.2 of the Xen user manual: 

You export a physical device as a VBD, and that's no different for DRBD.  It's 
been a while since I've done this, so I don't have a working config to paste 
here, but you should be able to use your drbd device just like any other block 

You'll probably notice a slight speed decrease in either case, unless you have 
slow disks and a fast network.  It's noticeable, but it's not bad at all.
