Stuff not mentioned here, you'll see JRockit Virtual Edition that runs on OVM without a full OS underneath -- this will compete with the VMW/tC Server/no OS stack on ESX. The OSS JVMs will have the drawback of having to carry a full OS underneath so even if they are as efficient as the closed JVMs you'll still gain advantage for going commercial. The OSS community needs to start looking at how to do the same on Xen. It doesn't make sense as much sense on KVM since you have a full OS there anyways.
