[libvirt] [PATCH] Error out on missing machine type in machine configs
Commit f1a89a8 allowed parsing configs from /etc/libvirt
without validating the emulator capabilities.
Check for the presence of os->type.machine even if the
VIR_DOMAIN_DEF_PARSE_SKIP_OSTYPE_CHECKS flag is set,
otherwise the daemon can crash on carelessly crafted input
in the config directory.
