For virtual_mem_map to work, I think domain0 needs to be given a granule of physical memory for each "island" in the EFI memmap. > Seems like that.

The problem is that the current design and implementation of Xen/ia64 management of physical memory is half-way between two good solutions. We will need to choose one solution soon. This should be a good discussion at the Xen summit.
