...booted has permission to map the PFNs from 0x20000-0x20200 and 0x40000-0x40200. If the domain is not given this permission (the default, since these regions are not part of the PCI device being passed to the guest) then the hypervisor crashes the domain when it attempts to map these regions (during init_memory_mapping). The domain will boot when these regions are not marked as reserved in the e820 map or when the PFNs 0x20200-0x40000 and 0x40200-0xc95d6 are marked as unusable. However, it is difficult to make this happen in any general case without knowing what reserved regions actually need to be marked as res...
