Why do you think it should? It's there simply to tell what the processor
is capable of, not to tell what your motherboard supports!!!
Actually, the VMX flag is something of a red-herring - although if the
cpuinfo is meant to be an accurate representation of the chip rather
than representing the way the environment is configured, then maybe it
shouldn't be hidden by Xen hypervisor.
The real issue is that Xen did actually know that I had a VMX chip, but
the message it gives is ambiguous. For the given situation I was faced
with, this message:
Error: HVM guest support is unavailable: is VT/AMD-V supported by your
CPU and enabled in your BIOS?
could have been something like:
Error: Xen has detected an Intel chip with VMX capability, but you must
enable support for this in your BIOS.
and then I wouldn't have been distracted by the vmx flag in cpuinfo.
