This is at best incredibly difficult since you have to cluster a huge
program (Linux). If the OS is closed it's impossible even to start.
If you do this at the virtualization level all you need is distributed
shared memory for guest RAM and clustering at the qemu level. If each
node gets its own PCI bus it shouldn't be too difficult.
