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

Wrt xen implementation, you can take a look at the function cpuid_hypervisor_leaves.
The min leaf for xen (MSR base address) is 0x40000000.

Btw, I don't follow the special handling of viridian domains in cpuid_hypervisor_leaves, when its taken care of in cpuid_viridian_leaves (both called from hvm_cpuid). Is it dead code ?

Hello, I have a question about xen-detect.c (which is posted

 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?

Yes, you should also confirm it.

If it is true then can anyone explain me how this can detect xen?

See the following thread.
