(note, please send a copy of replies to my e-mail, I am not subscribed to the
xen-devel list)
Before I get into details about the problem: I tried to identify the CPU as precisely
as possible (in case there are known problems with the specific model), but what I
found in the CPU identification information (as reported by the 'cpuid' instruction)
seems strange: unlike most Intel CPUs that report a sensible model name, which
generally matches the commercial name of the CPU, (e.g. "Intel(R) Core(TM) i5 CPU"),
on the server where I caught the EPT exception, the CPU model string reads:
"Genuine Intel(R) CPU @ 0000 @ 2.40GHz"
This does not look like any CPU that Intel sells. The family, model and stepping
numbers are 6 26 and 2, respectively. I did not find any reference to this particular
combination of model ID numbers, except in just one or two forum posts on the Web,
referring to the same non-descript model string quoted above. One of the posts even
suggested that this might be a non-production CPU chip:
http://www.spinics.net/lists/kvm/msg58258.html
Now, to the problem itself:
attempting to start a hardware-assisted virtual machine (HVM) on XEN 4.1.1 causes the
guest VM to crash instantly on startup. The crash is caused by a VM exit that is not
handled by XEN (and which cannot be handled in any way other than destroying the
guest VM): the VM exit reason is 49 (0x31), which is "EPT Misconfiguration".
According to the Intel Software Developer Manual (Vol 3B, Chapter 25 - VMX SUPPORT
FOR ADDRESS TRANSLATION), this VM exit means that an invalid value was found in the
extended page tables. Suspecting a software problem, I modified the XEN hypervisor to
provide additional information as follows:
- read and display the value of the EPTP VM control field
- read and display the value of the "Guest-physical address" control field (GPA)
- use the guest-physical address value to traverse the EPT structures and display
all 4 levels of page table entries that pertain to the GPA reported by the CPU.
I was not able to find any error in the EPTP value, nor in the EPT table entries,
they all seem to be valid. Below, I am including:
- the debug information displayed by XEN (with the additional instrumentation
that I added), with some bit-field analysis that I did manually (showing no
problems in the EPT entries)
- the CPU information (xm info and /proc/cpuinfo)
- memory map from BIOS
Also, the detailed DMI info from BIOS is attached as a text file (it doesn't show
anything different about the CPU, though).

Hm, I only saw those on pre-production hardware - aka, Beta CPUS. Are
you sure this is not one of those?

So does this work with a different CPU in that motherboard?

Yeah, those entries look fine. Certainly they don't have any of the

Misconfigurations", so I suspect there must be something odd about the
non-production CPU you're using.
