I got some Xen crash dumps. I can easily examine dom0's kernel. I'd like to examine the hypervisor. Possibly dumb question: how do I do that?
Best solution: Take the upstream crash version 4.0-4.5 and apply Oda-san's most recent "xencrash" patch from the previous post on this list: https://www.redhat.com/archives/crash-utility/2007-August/msg00022.html Then, if they are not already installed on the host system running the crash session, install: kernel-xen-<release>.rpm kernel-debuginfo-common-<release>.rpm kernel-xen-debuginfo-<release>.rpm And run the crash session like so: $ crash /boot/xen-syms-<release> vmcore Alternatively, you can use rpm2cpio to extract the "/boot/xen-syms-<release>" file from kernel-xen-<release>.rpm, its debuginfo file "/usr/lib/debug/boot/xen-syms-<release>.debug" from the kernel-xen-debuginfo-<release>.rpm. Then, if you put those two files in the same directory, you can do this: $ crash /boot/xen-syms-<release> xen-syms-<release>.debug vmcore The upstream xen doesn't do the the xen-syms-<release>.debug abstraction from the -g built xen-syms file, so the extra work is not required, so just "crash xen-syms vmcore" works.
