Subject: kvm on G4 processors?
I have tried to compile kernel 2.6.27 with kvm support on my
PowerBook
G4, but kvm option is not visible becouse kernel menu config
permit to
compile kvm kernel module only if you ave a PowerPC 440
architecture
and not G4.
But really kvm doesn't work for G4 processors, it's so different
the
architeture ?
In case kvm is working how to compile the kernel module on my G4?
I'm afraid that KVM now doesnot support G4.
440 belongs to BOOKE architecture, which is much different from G4.
We are at the begonning of porting kvm to 970(fx) atm, which is a
lot closer to a g4 than any booke.
Alex, which deployment of the 970 are you targeting:
1) IBM JS21/22 blades, that actually have a hypervisor already present
2) Apple G5, Bare metal, but has most hypervisor features physically
disabled
3) Any non-Book3E, which we call "classic" like 604, 750... and/or
Book3S, G3, G4, G5, P3, P4
If you choose (1), then your work would be harder but it should
apply to any IBM PPC64 or "pSeries" product
If you choose (2), then your work could be much easier, but it would
apply to G5s only.
if you choose (3), then its about the same as (2).
Right now we're targeting the PS3, as that's the platform we have most
free machines of here ;-). But the code as is should work for any bare
metal 970.
I haven't really looked into the hypervisor bits yet, but targeting
iSeries is definitely on the list. AFAIK we only need to take a deeper
look at that when we get to implement the MMU bits.
Another question is, when you do create your virtual machine, do you
intend for it to look exactly like a G5 machine (and support an
unmodified MacOS), a pSeries Machine (and emulate the pSeries
Hypervisor), or some new Machine that will require further
modifications to the OSes you will support?
I thought pSeries were the ones without Hypervisor? Basically the idea
is to expose a "random bare-metal" CPU to the userspace, with qemu
implementing the rest. One thing I was thinking of was even to go as
far as implementing a G3 guest on a POWER4+ host, but for now the plan
is 970 on 970.

BTW: I do not intend to discourage, and would be thrilled to see
_any_ of the above explored.
