[Crash-utility] crash: cannot determine vcpu_guest_context.ctrlreg offset

[Bob Clark]

I'm trying to analyze a xen linux guest crashdump and I'm receiving the
following error:

crash: cannot determine vcpu_guest_context.ctrlreg offset

The crashdump was produced from Xen 5.0.0 by setting the
actions-after-crash parameter to coredump_and_restart, and then crashing
the guest VM. I'm using crash version 4.0-7.4.

Thanks in advance for any help.
