Its not strictly about kexec. The other patch I sent out will place the shared info page at 0xFE700000. If that range is not within a E820_Reserved area and if the old hvmloader makes allocations within that range, that other patch needs to be changed so that the shared info page is done either at 0xFE700000 or within RESERVE_BRK (as it is done currently). Is the source code of that old RHEL available somewhere, did they patch hvmloader at all? Providing a E820 map from a guest which was started on such old dom0 would be a good start.
