On Fedora 11, you need to add:
/usr/sbin/fence_xvmd -LI virbr0
... to /etc/rc.d/rc.local on the "host" machine.
Other than that, you can just add a disk to two machines using
virt-manager (it complains, but does the right thing) to create a shared
"disk" for use by GFS2 or clustered LVM (or for use as a quorum disk).
If you're running a cluster of VMs on a single host using NATted
network, you don't even need to distribute fence_xvm.key (or any keys at
I'll make a note to update that VMClusterCookbook page; it's out of date
and xen-specific. This is bad because the cluster and associated tools
are all libvirt-based and *NOT* specific to any virtualization
