It's been a long time since I've looked at the particulars of a Xen dumpfile given that Red Hat has discontinued Xen for KVM, so I'm a bit rusty. In any case, upon the first memory read, while trying to walk through the page table data to resolve a kernel virtual address, it comes to a dead end. I have no idea why, nor do I have any further suggestions. Can the SLES-qualified members of the list confirm that "xm dump" still creates dumpfiles that crash can handle?
