I'd like to set up three virtualized server on one box running Ubuntu KVM. I'd also like to have a second machine mirroring the above mentioned on a cluster so that if the first machine physically goes down, this one would take over. Is this setup possible and if so, does anyone have a link to a articles or walkthroughs on this? | ||||

Yes, you can do it. I don't have any articles to hand, but we're using DRBD, heartbeat, some simple shell scripts, and Puppet to automatically provision, replicate, failover and maintain our VMs. | |||

depends on how exactly you want things to failover. if you mean the scenario where if one host fails, all VMs are restarted on another - RHEV can do that easily. if you're looking for 0 downtime - you want vmware FT, which costs an arm and a leg | |||

Maybe the new Cloud Computing Solution from Ubuntu (which is based on KVM) is worth a look. http://www.ubuntu.com/cloud/private I have no real experience but maybe it's a modern approach to your problem. :-) | |||
