I was going to mention this as well.
BTW, lpar is OLD. Predates solaris, and isn't containers. It is HARDWARE based OS partitioning, IIRC. Thus it is basically bomb-proof, but it has more overhead than os-level virtualization. WPAR is more like solaris containers, but, again, not exactly the same. Don't ask me what the difference is, I don't know.
Linux can virtualize the network stack (http://www.ibm.com/developerworks/li...al-networking/).
If worse comes to worst, you can always virtualize EVERYTHING with k/qemu (kqemu is qemu with some additional kernel modules for speedups, though this might be merged with qemu now).
Of course this entails performance hits unless you enable paravirtual drivers.
