Hi,
My server is Suse Linux SLES11 sp2 verison ,
HjCloud:~ # uname -a
Linux HjCloud 3.0.38-0.5-xen #1 SMP Fri Aug 3 09:02:17 UTC 2012 (358029e) x86_64 x86_64
x86_64 > GNU/Linux
I know to get dom0 kdump core by "echo c >/proc/sysrq-trigger ",
but don't know how to get xen hypervisor core, then how to analysis
the hypervisor core by Crash software.
Can you help me?
Does it work? If yes then /proc/vmcore
contains proper memory image with
Xen dump. Just get copy of it,
get xen-syms (or something like that;
I do not know how it is called in SLES)
and pass them to crash tool. That is it.
