I mean in case of a hotplug after the migration, we should check any overlap with current existing RAM/MMIO, right? So we need to know current existing guest RAM/MMIO layout since this ultimate e820 table is just built by hvmloader, not in xen internal. Thanks Tiejun 7. One RMRR can be mapped for multiple devices in multiple domains So we may need to do something to stop this potential damage between domains.Good point. We should enforce these to be group assigned (along the lines of what is already done with XEN_DOMCTL_get_device_group).
