I have been working off and on with Xen and KVM on a couple of test hosts for that past year or so and while now everything seems to function as expected, more or less, I find myself asking the question: Why?
I saw a company architecture presentation where they had paired servers with 2 VMs each + DRBD + heartbeat... So, on each server there is an active VM and a 'backup' VM, crossed. If one server goes down, the 'backup' VM on the second server would be activated.
