[Xen-devel] VMM detection

["Wu Bingzheng" <wubingzheng@xxxxxxx>]

Hi,

In a paper named 'Analysis of the IntelPentium's Ability to Support aSecure Virtual Machine Monitor'
<http://www.usenix.org/events/sec00/full_papers/robin/robin_html/index.html>,
it lists 17 instructions in Pentium instruction set, which are virtualization sensitive
and unprivileged.
Using these instructions, we can detect VMM on a PV guest.

I want to know if we can use these instructions to detect VMM on a HVM guest.

(I issued a message a few days ago about VMM detection. But I deleted that mail by mistake, so
I give another message here.)

Thanks,
Wu
