Description Chris Lalancette 2009-09-14 08:34:51 UTC
+++ This bug was initially created as a clone of Bug #499648 +++

Description of problem:
I'm following the test case here: https://fedoraproject.org/wiki/QA:Testcase_Virtualization_XenDomU_Crash_dump

While trying to make the F-11 Xen domU take a crashdump using:

# echo c > /proc/sysrq-trigger

all I get is a message on the console like:

SysRq : Trigger a crashdump

Looking at dmesg, I also see this:
Kexec: Warning: crash image not loaded

However, for a Xen domU, we don't need a kexec crash image loaded; we just have to inform the hypervisor that we are crashing, and the dom0 will take an image of memory for us.

Miroslav,
     If you have time to look at this, this would be a good bug to fix in upstream and then port into Fedora.  The ability to crash dump is very important for debugging future issues.

This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.

Still need to come up with the best way to deal with this. Will do as work for 6.1.

This should be resolved by bug 614476 when the work for that is completed. Dupping.
