Commit1787cc1679("libs/guest: Move the guest ABI check earlier into xc_dom_parse_image()") broke starting the xenstore stubdom. This is due to a rather special way the xenstore stubdom domain config is being initialized: in order to support both, PV and PVH stubdom, init-xenstore-domain is using xc_dom_parse_image() to find the correct domain type. Unfortunately above commit requires xc_dom_boot_xen_init() to have been called before using xc_dom_parse_image(). This requires the domid, which is known only after xc_domain_create(), which requires the domain type. In order to break this circular dependency, call xc_dom_boot_xen_init() with an arbitrary domid first, and then set dom->guest_domid later.
