This can cause crash when attach happens after reboot. Restore initial good version of resource table before re-creating virtio devices. As part of this, first the server takes the resource table snapshot to before any IPC events are in place to prevent this issue during system-init. Secondly helper.c will call get_resource_table so that the future call to restore_initial_rsc_table will have the resource set up. Otherwise the snapshot can still fail if the resource is not set up.
