I am looking for anyone that can give me some solid advice on setting up XEN for clustering... I want to do a failover redundancy for production with Virtual Servers. I am hearing really, really good things about XEN. I've initially tried setting this up with CentOS Linux, and it did not work. However, I heard from a good source that this will work great with Debian sid Linux. Any experiential advise on setup of this with clustering options would be greatly appreciated. The most thorough answer receives the points.
