Aren't they mutually exclusive? Is this one for stable?

This patch is for S390x guests, so qemu-system-s390x refuses to start without -enable-kvm. Alex

Currently only the S390 KVM target works. To keep users from accidently not using KVM, let's not even initialize the machine when KVM is not used. Signed-off-by: Alexander Graf <agraf@suse.de> --- hw/s390-virtio.c | 7 +++++++ 1 files changed, 7 insertions(+), 0 deletions(-)
