KVM for PowerPC only supports embedded cores at the moment. While it makes sense to virtualize on small machines, it's even more fun to do so on big boxes. So I figured we need KVM for PowerPC64 as well.
This patchset implements KVM support for PPC64 hosts and guest support for PPC64 and G3/G4. To really make use of this, you will also need a modified version of qemu that can deal with KVM on desktop cores. I will send out patches for those later, but want to get feedback on the kernel side first. In the meanwhile, use the qemu version from http://www.powerkvm.org/powerkvm.git which already includes all required patches to run PPC32 and PPC64 guests.
