I'm kind of surprised to hear you say that.  One of libvirt's goals is
portability, so if it doesn't work on Solaris now, you should mention
it on libvir-list, and I wouldn't expect getting it to work would be
that troublesome.  Personally I don't use Solaris, but if it's
something you want, you should ask and see what other people's
experience is.
