Right place, wrong time.

It has already been asked (3-4 weeks ago by me).

The answer is, no there is not a MOL equivalent at this time and there probably will not be for the foreseeable future.
It seems that with such programs as VMware and Parallels for Linux that there is not much call for a program like MOL.

Personally, I loved the ability to use both simultaneously and just CMD-OPT-F7'ing my way back to Linux whenever I was not in need of a Mac-Only Application.

In the mean time, I would take a look at one of those two, or take a look at QEMU/KQEMU.

Best of luck, but in the future do a search or two. Topic Name was almost identical.

Talking about Qemu / kQemu..
Has anyone succesfully made a unix os boot under qemu-system-ppc?
I've tried Debian-ppc and OpenBSD macppc and none of theme would boot..
btw qemu emulating x86 works flawlsess with win2k and slackware..

About kQemu: am i wrong or it is a closed source kernel module available only under x86 platform?

If you need to use a PPC os on PPC hardware under Linux, you might want to look at MOL (Mac On Linux). That way you do not have the hardware emulation so it runs very quickly. Plus, you can always CTRL-ALT-F7 for Linux, CTRL-ALT-F8 for Mac/Other Linux.

From my litte eperience, it seems that MOL is quite fast, at least when it comes to video. When using qemu it seems at least 10 times slower when video is used. I dunno about VMware.

I find it funny that there is a fast virtulizer for PPC that is free and vmware for x86 isn't free. Is it easier to make a virtulizer on the PPC architecture than on x86?

Yes.

On PowerPC, the CPU will trap when system registers are read and the CPU is not running in kernel mode. On x86, you can of need to do more rewrite or tricks to get it to work. There are other issues to consider probably as well.

Some like Xen get by by modifying the host/guest OSes. What is inconvient is that Windows kernel source is not available. Mac OS X kernel source is available. So, I guess someone could add OS X support to Xen and have good performance.

The other things is that Mol provided network connectivity between OS, drivers for sound, etc. These drivers link the OSes require some implementation work. They are part of making the good user experience.

BTW, PowerPCs used in IBM servers and in the PlayStation 3 have hypervisor support. Google hypervisor or LPAR for more info. PowerPC used in Macs don't have hypervisor support. The hypervisor acts like the VMWare etc. It is just that it has CPU/hardware support and that all the OSes run on top of the hypervisor (there are no host/guest OS concept -- or all OSes are guest to the hypervisor if you like).
