Hi,

This information is obsolate. sorry.
You can analyze a vmcore using crash command for both
xen hypervisor and domain-0 directly.
You can get the crash command in the following URL.
http://people.redhat.com/anderson/
to analyze the xen hypervisor, run
$ crash xen-syms vmcore
then it start the session for the xen analysis
to analyze the domain-0, run (for example)
$ crash System.map vmlinux-with-g vmcore
then it starts the session for ordinary linux analysis for domain-0
a vmcore is not necesarry to modify at all.
Thanks.
