This I think we should probably move those out of the opt/ namespace space, as this is reserved for user-defined files. I think either "etc/efi/" or "efi/" is useful (so we don't have different names on ovmf and aavmf). Possibly add "pcd/". Maybe even support setting *any* pcd via "efi/pcd/$name" (just an idea, not sure whenever that is useful and is possible without being too invasive). > - "opt/ovmf/X-PciMmio64Mb" controls the size of the range from which Hmm. Leave as-is for now I'd say. If we decide to keep it we should probably rename it and place it below etc/, next to reserved-memory-end. Export the size in bytes, like reserved-memory-end does. Add an option to qemu to set it, so you can specify the size as "32G" using the standard qemu size parser. cheers, Gerd
