[XenAccess-devel] Getting the IDT of an HVM guest

[Matthew D. <ma...@at...>]

Hey,

I'm trying to retrieve the IDT of an HVM guest (XP/Vista) but the
xc_vcpu_getcontext() function doesn't return anything useful.  I asked on
the Xen devel mailing list and was told:  

"Unfortunately the IDTR is not exposed via vcpu_context for HVM guests. The
only way to get it right now is to do a hvm save hypercall and then parse
the pickled state to find the IDTR. It actually should be quite easy."

I was digging around in the Xen source and found a hvm_save() function but
it isn't in the Xen headers I have.

Have you looked at this at all?  

Thanks
