I would suggest a careful examination of the efficiencies of different hypervisor architectures. You can lose a lot of optimization if the hypervisor abstracts too many hardware details (thread to processor affinity is one such example). So while the more general purpose the hypervisor (abstracts the most details) the fewer opportunities for the OS to optimize (and in some cases they futilely optimize - like a compulsion for a pointless or destructive activity). The relevance here is that the abstraction layer presented by Solaris zones is higher in the stack (near the user space layer) so all of the platform specific optimizations are available to the kernel. When you begin to think about the impact of optimizations such multiple page sizes and memory placement, these details can become very important. And of course reduced VM pressure from sharing a common (but secure) buffer cache and shared libraries.
