Once Gerd imports a new SeaBIOS blob, QEMU should be able to boot
OS X "out of the box". Of course, there are stil some caveats:
1. We still need the Chameleon bootloader (to work around EFI):
- by loading only its stage-2 component (named "boot")
via the "-kernel boot" command line option to QEMU
(this is how I'm starting it right now)
- by installing all of Chameleon to the guest disk image,
the way hackintoshes do (I haven't tried this, but thought
it's worth mentioning).
2. e1000 flakiness:
- link negotiation is flaky (I have a patch, but was told
and agree that it morally belongs in the BIOS layer)
- Mavericks doesn't like the current e1000 model
(E1000_DEV_ID_82540EM); there was a patch sent to the list
to allow selecting among different e1000 models, I think
it was:
http://lists.nongnu.org/archive/html/qemu-devel/2014-02/msg04411.html
Mavericks likes E1000_DEV_ID_82545EM_COPPER, but Windows
won't work with that, so picking which model to use from
the command line would be nice. The patch seems abandoned
at this point, so I might contact the author and ask if
he minds me picking it up and continuing to polish it until
it's acceptable :)
- virtio-net works with an "aftermarket" driver, verified to
work both in MountainLion and Mavericks. It's what I'm using
right now.
AFAIK, that's everything :)
There's a GSoC student (Reza Jelveh) who will be working on trying
booting OS X with OVMF (piix only for now).
I'm toying with the idea of maybe getting OVMF to work with Q35,
but I have absolutely no idea yet how big of a job that might be,
and whether I'm mentally equipped to tackle it myself, in my "spare time" :)
Last but not least, I keep a "current state of OS X on QEMU/KVM"
writeup online at
http://www.contrib.andrew.cmu.edu/~somlo/OSXKVM/
so any new and interesting developments should show up there in a
reasonably timely way...
Cheers,
