[ Cloud Computing ] Re: why virtualization?

My understanding is Azul's solution is JVM-only. 

The "generic" VM solution allows different flavors of guest VMs that can host legacy apps.

Good point. The Azul stuff is pretty cool, and if I understand you, it sounds like it is now more or less multi-tenantizable?

Given that there are providers out there basing cloud-ish offerings (by which I mean mostly automated provisioning, no long-term contracts, and capacity-based pricing) on tech from Xen, 3tera, VirtualIron, Sun, and Msft (did I miss any?), I'm wondering why there is no provider offering an Azul-based service? For that matter, why is there no provider offering z/os based service? Wouldn't that be a pretty cheap way to get thousands of lamp stacks online?
