Virtualization does not work that way these days.  Maybe it will eventually, though.  It would definitely be another way to solve scalability issues.


At this point in time, all of the major virtualization platforms limit each VM to one physical server.  You cannot span a single VM across many physical servers.

Hello Everyone,

I have an idea for setting up a virtualisation cluster, where the raw CPU power assigned to each DomU could be split across multiple physical servers.

Does such a solution already exist? This would be fantastic for a "premimum" VPS hosting solutions where customer would be able to scale their VPSes to speeds and cores not possible with a single physical server. I appreciate that the latency that this would introduce would maybe make this project infeasible, nonetheless I'd be interested to hear everyone's thoughts

What would be even cooler if the RAM was distributed as well...
