Toolstacks may specify a VM generation ID using the u.hvm.ms_vm_genid field in the libxl_domain_build_info structure, when creating a domain. The toolstack is responsible for providing the correct generation ID according to the Microsoft specification (e.g., generating new random ones with libxl_ms_vm_genid_generate() as appropriate when restoring). Although the specification requires that a ACPI Notify event is raised if the generation ID is changed, the generation ID is never changed when the domain is in a state to receive such an event (it's either newly created or suspended).
