Construct Xen guest e820 map with a hole between 640K-1M. It's pure luck that Xen kernels have gotten away with it in the past. The patch below seems like the right thing to do. It certainly boots in a domU without the DMI problem (without any of the other related patches such as Alexander's). Signed-off-by: Ian Campbell <ijc@hellion.org.uk> Cc: H.
