Also available in some commercial distro's of OpenStack, like Metacloud. I always cringe when people believe VMware HA == HA solution. No. It's part of a HA strategy, but 30 seconds to declare a node is dead, and then however long booting up a big server full of VM's takes - if your storage is not that great, that can be quite a while (boot storms are fun). If up to 15 mins of complete downtime counts as HA for you, great! But that's already risking 99.99% SLA.
