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.
