We used porting plan 3 from here, in this case running a Fedora appliance. A curious side-effect of this is that libguestfs on Mac OS X can read ext3 partitions and LVM, something which OS X itself wouldn’t normally be able to do. On the downside, it’s kind of slow, because qemu is not accelerated on OS X.

Interested people should look at the lengthy series of patches posted on the mailing list.
