I'm trying the Mac_OSX_on_KVM Howto above.
I'd like to boot an existing, bootable Mac OS X 10.5.5 GPT formatted,
external USB HDD, which boots fine on my 4,1 MBP.
Does anyone know if Alexander's kvm-osx-bootloader can boot real, host
managed HDDs, or is it dependent on something associated with disk
image files, created by qemu-img?
I don't have the message in front of me now, but I think I was getting
"device not found" when I used -hda /dev/sdc or -hda /dev/sdc1.
