Everything else said aside, we use DRBD in a master-slave
configuration (with ext3) between pairs of xen guests for a couple of
years now and it works great.
We are experimenting with write-write and GFS but so far haven't had
all the time needed to crack this.

This is on CentOS 5.2 xne guests. CentOS 5.3 should bring GFS2 into
production quality which might make things better.
