From bbf45ba57eaec56569918a8bab96ab653bd45ec1 Mon Sep 17 00:00:00 2001 From: Hollis Blanchard Date: Wed, 16 Apr 2008 23:28:09 -0500 Subject: KVM: ppc: PowerPC 440 KVM implementation This functionality is definitely experimental, but is capable of running unmodified PowerPC 440 Linux kernels as guests on a PowerPC 440 host. (Only tested with 440EP "Bamboo" guests so far, but with appropriate userspace support other SoC/board combinations should work.) See Documentation/powerpc/kvm_440.txt for technical details.
