[Xen-API] Get IDT of virtual machine

[Matthew Donovan <matthew@xxxxxxxxxxxxxx>]

Hi,

I'm trying to retrieve and print the interrupt descriptor table of a guest
OS but every address is coming out 0x00000000.

Here's what I'm doing:

    vcpu_guest_context_t ctx;
    int i;

    int res = xc_vcpu_getcontext (xai->xc_handle, xai->domain_id, 0, &ctx);
    if (res < 0) {
        fprintf (stderr, "xc_vcpu_getcontext failed!\n");
        return;
    }   

    for (i = 0 ; i < 256 ; ++i) {
        printf ("Interrupt %d: Address 0x%08x\n", 
                i,
                ctx.trap_ctxt[i].address);   
    }


I'm using Xen 3.1.2 on Fedora Core 8.  The guest OS's have been XP Pro and
Vista Ultimate, though I assume that part doesn't matter since the IDT is a
processor structure.

Any help is greatly appreciated.
