Xen HA with multiple servers
Hi all,
I am looking for information regarding high availability of Xen. What I want to accomplish is that when one server fails, other servers take over. I know how to do this with 2 servers. However I have 5 servers and each doesn't have enough resources to take over all the domU's from the server that fails. But if 1 machine fails the 4 remaining servers have more than enough capacity together to take over the domU's of the failed server.
How do I get this done? All domU's are stored on an iSCSI SAN and are made available to all servers. So I guess, I some how need to check if there is enough CPU and RAM available.
I use heartbeat to check if dom0 is still running on the servers.
TIA
