Marek Marczykowski-Górecki b2bbadc63c hw/xen: detect when running inside stubdomain
Introduce global xen_is_stubdomain variable when qemu is running inside
a stubdomain instead of dom0. This will be relevant for subsequent
patches, as few things like accessing PCI config space need to be done
differently.
