If virtual machines with live migration is what you're after, vmware is not your only option. You can get largely the same effect without involving any iscsi/FC/SAN tech with another open source project, which happens to originate from the same place as Kubernetes: http://www.ganeti.org/ http://www.ganeti.org/ Ganeti has been battle-tested for about a decade too, supports an assortment of storage backends, including some clustered ones like Ceph, can do live migration between hypervisor nodes, and it's a nicely maintained Python app with some Haskell parts in it. ganeti came out of my team at google in the mid 2000s, fwiw. I did not work on it, but I've certainly used it. It's pretty nice.
