;)
Do we build storage mpath on such platforms?
No. This is the ./configure output on OSX using libvirt 0.8.8, with most of
the stuff enabled that can be made to compile:

With some persistence, it's also possible to get:
+ libssh2 support compiled in, although that can tricky as there doesn't
seem to be a way to pass non "/usr/local" include directories to
configure for it it
+ Avahi support can also be made to compile, but has a huge dependency
chain on OSX so I don't bother. That pulls in compiling of all X
windows, no idea why.
+ libpcap. I've seen it compile in before, but haven't really looked
at what this gives.
Hope that's useful info. :)
