Re: [Crash-utility] xendump image with full-vitualized domain

Much of the information that crash uses to find its way around a xendump currently depends upon information *inside* the para-virtualized kernel. In your attempt above, it needs data structure information for the vcpu_guest_context structure, in order to get a cr3 value -- which it uses to find the phys_to_machine_mapping[] array built into the kernel. But obviously there is no phys_to_machine_mapping[] array in fully-virtualized kernels, so no pseudo-to-physical address translations can be made. I'm not sure what the best solution is for fully-virtualized kernels. Perhaps what is needed is yet another tool that takes a xendump of a fully-virtualized kernel, and turns it into a recognizable vmcore? Whatever it is, an alternative manner of translating the "physical" addresses in the fully-virtualized kernel (which become pseudo-physical addresses in the xen environment) and find them in the xendump.
