I am looking to understand how other people have built clusters of KVM host servers. I am especially interested in how people solved the problem of having them automatically failover if one node dies?

Looking at your blog post the thing you miss is a clustering solution like RHCS or Linux-HA.
it's automated in RHEV

RHEV still has a Windows only gui so still not an option, plus a completely different cost associated with it, thanks thought. Sep 22, 2010 at 19:17

If you read the news, the windows-only part is going to be gone. As for everything else, it is of course totally up to you– dyasnySep 23, 2010 at 4:01

1not an easy task, but it's been done. RHEV3 is in public beta, and should be released soon enough– dyasnyNov 6, 2011 at 16:18
RHEV 3.0 will be released on the second half year of 2011, which will switch from Windows + .net to Linux + Java.
You can try ovirt, which is the open source version of RHEV. http://www.ovirt.org/Home It does HA and live migration. It also supports some OpenStack parts.
