Apache CloudStack has already proven its abilities to scale to tens of thousands of physical XenServer nodes, but a number of traditional networking schemes don't work. VLANs max out at 4096, Layer3 isolation (aka Security Groups) helps scale to a degree, but you lose a lot of flexibility in the process.
