QEMU v1.7 has been released more than 8 years ago, so most people should have updated their machines to a newer version in those 8 years at least once. Thus let's mark the very old 1.x machine types as deprecated now. Signed-off-by: Thomas Huth Message-Id: <20220117191639.278497-1-thuth@redhat.com> Reviewed-by: Michael S.
