Summary: Dell syscfg bios tool doesn't work on PowerEdge 860/1850
with Xen
Product: Xen
Version: unspecified
Platform: x86
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Hardware Support
AssignedTo: xen-bugs@xxxxxxxxxxxxxxxxxxx
ReportedBy: baco@xxxxxxxxxxxxx
Xen Memory mapping isn't the same on Dell PowerEdge 860/1850
and on Dell PowerEdge 1950 with the same version of Kernel Xen.
On Dell PowerEdge 860/1850 Xen "syscfg" a low level tool from
Dell DTK aren't able to access Dell BIOS memory area. See the
strace in this message. The same tool works on Dell PowerEdge
1950 with same Xen configuration.
Maybe this is related to CPU virtualisation feature because
when virtualisation feature is present (Dell 1950) it works
and when not it doesn't work (Del 1850 / 860).
Please give me some feedback about this.

syscfg uses a different memory area to interface with BIOS, so it is
likely that this memory area is not mapped properly by XEN.
You can clearly see the address it is trying to probe in your systrace
output. You might talk to the xen people to see if they can fix this.
