That makes a lot of sense... I don't know that I really needed the full
suite, as I don't think I'm aiming for that level of HA for the hosted
systems.
I'll look into it. Can you provide me any better links than what a google
search would provide?
Thanks!
David.

KVM/libvirt makes moving running VM's from one host to another a no

Right now I'm thinking something like KVM + libvirt + heartbeat/corosync +
pacemaker + DBRM on Ubuntu 10.04 with 3 or 4 nodes - 2 hosts, 2 storage,
or 1 host, 1 host + storage, 1 storage.
Personally, I had been planning to do it with mdadm multi-path & RAID
1 over iSCSI. Seems to be a more straightforward solution than using a
full HA setup if the purpose is to ensure storage remains available
when a node is down (for maintenance or otherwise).
