I'm searching for open source software to create my own cloud computing environment, like Ubuntu UEC or Eucalyptus.
What I need is that each virtual machine can use resources from multiple nodes (CPU, RAM). And apparently, neither UEC nor Eucalyptus offer this feature.
I have 5 hardware nodes with each 2x Quadcore. I want that one VM can use up to 20 cores (in this case).
Which open source software can meet this requirement?
At first, I think this is possible with current technology, with computers connected using gigabit network.
Companies like the VPS.net offer services that make a single virtual machine to be formed from the resources of multiple nodes. (At least it seems to be so)
Is this just an abstraction made by VPS.net? Is this approach recommended?
