First avoid posting in Hideous Trash Makeup Language, thanks.
Second, there is no hope of making Xen work on the existing G4. The hypervisor support is equivalent to a third privilege level in the processor. The G4 only has two privilege levels, and I can't think of an efficient way of emulating a third level (you'd have to run the OS in user mode).
Well... MOL does it pretty well :) It's more difficult but technically possible without too much performance loss.
Still, it is currently impossible to run a linux 2.6 kernel on top of MOL.
If I understand things correctly: - Xen isn't yet available for powerpc and some think it'll never be. - MOL won't run 2.6, _and_ I couldn't find any explicit mention of it supporting 10.4, to say nothing of 10.5
It all seems a bit overconstrained.
FWIW, I did find Xensource's 05-Dec-05 press release which states: [...]a port of Xen to IBM’s Power PC architecture by IBM is close to completion, signaling broad cross-platform adoption of Xen.
So one can hope :-)
