Re: [libvirt] [PATCH 3/3] qemu: fix default machine for argv -> xml convertor

Historically the argv -> xml convertor wanted the same default machine as we'd set when parsing xml. The latter has now changed, however, to use a default defined by libvirt. The former needs fixing to again honour the default QEMU machine. This exposed a bug in handling for the aarch64 target, as QEMU does not define any default machine. Thus we should not having been accepting argv without a -machine provided. Signed-off-by: Daniel P.
