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?


I recommend reading this tutorial:


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. – fatherlinux Sep 22 '10 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 – dyasny Sep 23 '10 at 4:01
  • Yeah, thanks I read that like 6 months ago, still nothing – fatherlinux Dec 29 '10 at 21:01

    not an easy task, but it's been done. RHEV3 is in public beta, and should be released soon enough – dyasny Nov 6 '11 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.
