Right. However, note that this only affects one patch in the series (patch 3). Patches 1-2 are useful to unify Xen-specific behavior with other hypervisors, and patches 4-6 are useful to future-proof ACPI table sizes for migration. > IMHO we should either really parse the memory map, or reserve more > space. I agree. However, we need to cater for a fixed initrd loading address until this is done. And even after linuxboot.bin is improved, the older version will be used when migrating for older QEMU machine types, so it is important to have a decent fallback. Paolo
