From 938368f8382ca94c5156c44ad85a06cf9e4f8f8f Mon Sep 17 00:00:00 2001 From: Andrea Bolognani Date: Wed, 30 Sep 2015 11:58:58 -0400 Subject: [PATCH] qemu: Add conditions for qemu-kvm use on ppc64 qemu-kvm can be used to run ppc64 guests on ppc64le hosts and vice versa, since the hardware is actually the same and the endianness is chosen by the guest kernel. Up until now, however, libvirt didn't allow the use of qemu-kvm to run guests if their endianness didn't match the host's.
