Whether it's "supported" depends entirely on what you do with this sort of setup. :-) For KVM or Xen it's generally fine, for KVM it's indeed something of a prerequisite. I suppose you want to know what you can do with these "partitions" from the host environment. Check out the man page of kpartx and play with the devmaps which "kpartx -av /dev/drbd2" generates. Be warned, though: you're on your own in coordinating your devmap access with that from KVM. In other words, don't mount and modify any of these filesystems while KVM is using the device.
