Re: [Xen-devel] memory calculation mismatch between e820 and guest RAM size

[Keir Fraser <keir@xxxxxxxxxxxxx>]

I don't understand what the problem is that you think needs fixing. All the
memory allocated in xc_hvm_build.c:setup_guest() is marked as E820_RAM in
the e820 map (except for EBDA and BIOSROM regions).
