[hybrid] : mmap pfn space...
Hi Ian/Stefano,
So, I''m back to using pfn space from maxphysaddr below. Stefano, you
suggested ballooning, but that would be just too slow. There are lot of
pages to be mapped, 4k at a time during guest creation, and I am afraid
ballooning and hypercalls to populate EPT will be pretty slow.
OTOH, there is tons of address space available between max-physaddr and
max pfn in dom0. Stefano,

set_phys_to_machine not exported?
I''m trying to compile pvscsi out-of-tree, and I''m getting an error that set_phys_to_machine is not defined when I try to load the module (with the warning to that effect at compile time too). This used to work fine in pvops.
It seems that netfront uses that symbol in a module so I''m confused as to why pvscsi can''t... any suggestions? Is it one of the virtues of
