I have the problem where memory past the first memory hole isn't seen by xen 
on x86_64.  I have done a lot of searching on the issue and tried just about 
every solution that seemed even remotely possible of solving the problem, but 
nothing has helped. There is a thread at 
http://archive.netbsd.se/?ml=xen-devel&a=2007-04&m=3895925&list
where there is a bit of discussion about grub not passing on the memory map 
adequately.  In one post at 
http://archive.netbsd.se/?ml=xen-devel&a=2007-04&m=3988838
Keir mentions that past 3.0.5 xen will be able to get the map for itself.
My base install is CentOS5 on x86_64, updated to latest available.  That shows
Xen version 3.0.3-rc5-8.1.8.el5, so I downloaded 3.1.0 but it did not make a 
difference.  Is there an option that causes xen to get the memory map for 
itself instead of relying on grub?
Thanks,
Calvin
