I got OSX running in Qemu with only 192 MB and it was working.
Even if I gave OSX more RAM in Qemu, it was still very slow.
On the apple website, it says that you must have "At least 256MB of physical RAM" to run tiger. Seeing as Featherlinux is going to be taking up a small portion of the ram, we are going to need more than 256mb. I have tried with 256mb and I think that is what is causing OS X to crash so I think the minimum amount of ram that we need to get OS X running is 384mb. That's only a 256mb + 128mb.
What do you mean? Did they get it running natively or using qemu?
