We use Linux-ha (http://linux-ha.org) and drbd instead of a shared
disk.  It plays nicely with Xen.  In one instance, we've got two Xen
servers, each housing 4 virtual servers in separate clusters, all
sharing data with drbd.  It works very well.  We're also using CentOS,
so none of the software used costs anything.
