You may look at fence-virt.
I use fence-virtd-libvirt-qpid (with two my patches which fix grave
bugs, names of patches say for themselves) and fence_xvm.
It's still not ideal (f.e. it does not work if several hosts know one
VM), but it may work well under some circumstances:
* You set up qpid server
* You run fence_virtd on every host and publish libvirtd data on that
qpid server
* You ensure that only one host has any VM listed in qpid (read: in
virsh list). F.e you unconditionally use virsh undefine after vm is stopped.
* You fix its bugs (at least with my patches)

Patches are attached.

Best,
Vladislav

P.S. Patches could be also interesting for fence-virt author if he reads
this list. It would be great if somebody point him to them otherwise.
