I'm trying to run dmidecode on a linux 2.6.38.7 kernel running as Dom0 to find 
out about the underlying hardware. Unfortunately when I run this under a Xen 
4.1.0 all I get back is an error message saying "No SMBIOS nor DMI entry point 
found. sorry.". If I run the same system, but not under the Xen 4.1.0 
hypervisor, everything works fine, and when I did this under a 3.x Xen 
hypervisor everything worked fine too.

Since dmidecode looks at /dev/mem to find the information, has something 
changed to how /dev/mem is handled? Is there a way I get dmidecode to work?

thanks,

Anthony Wright.
