Yes, Solaris 10 zones are nice but limited in the way that it can only
"run" another instance of the same version of Solaris. It is useful to
some extent and runs without *any* performance loss.

But upcoming BrandZ[1] (Solaris 11 zones) will have additional syscall
layer which will allow to run OpenSolaris-based distribution like
NexentaOS[2] without *any* performance loss and Linux-based distributions
with minimal performance loss (5-10%), which is way more efficient than

BrandZ patches are freely available now and we are planning to include
them into the NexentaOS once they are part of an official build.
