Re: [Xen-users] xen-detect.c question

Thank you very much.
You helped me a lot =)

Well, I'm not sure about the internals of Xen, but I can read C. It looks like it should be able to detect HVM and PV.
What it does is:
Executes some assembly code to get the id of the cpu
If that returns "XenVMMXenVMM" then we're running Xen in HVM mode
Otherwise it tests for PV mode.
It executes the same assembly code, but this time in pv context (which will only work on a PV machine)
If that succeeds then we're running Xen in PV mode.
If that fails then we're not running Xen.

Hello, I have a question about xen-detect.c (which is posted http://lists.xensource.com/archives/html/xen-changelog/2007-02/msg00075.html here)
It says that by running this program xen PV and HVM can be detected. First of all, is it true that it can detect HVM (hardware support Xen)? Can anyone confirm this? If it is true then can anyone explain me how this can detect xen?
Thank you in advance. ------------------------------------------------------------------------
