Comment 2 RHEL Product and Program Management 2007-06-07 15:44:38 EDT
This request was evaluated by Red Hat Product Management for
inclusion in a Red Hat Enterprise Linux release.  Since this
bugzilla is in a component that is not approved for the current
release, it has been closed with resolution deferred.  You may
reopen this bugzilla for consideration in the next release.
Comment 7 Stephen Tweedie 2007-06-12 15:16:56 EDT
One other detail: not only will system-config-kdump need to enable setup for
Xen, it will also need to make sure it's the _right_ setup, which isn't
precisely the same as for non-xen kernels.

In particular, the "crashkernel=" arg needs to be on the "kernel xen.gz..." line
in the grub.conf, not the "module vmlinuz..." line; and the dump kernel will
need to be loaded "@32m", not the default "@16m" that non-xen uses.
Comment 8 Jarod Wilson 2007-06-14 11:50:23 EDT
nb: I had to deal with the same issue in the firstboot module, and its fairly
straight-forward. We obviously set the offset to 32 instead of 16 on x86 and
x86_64 xen, and then just use grubby with --mbargs instead of --args to add the
parameters to the correct line in grub. These changes are in the latest
kexec-tools (which carries the firstboot module). Not sure yet how this will all
shake out if/when we get around to ia64 xen kdump...
Comment 9 Pete Graner 2007-08-15 16:57:18 EDT
Not an approved component moving to 5.2 for consideration
Comment 10 Jarod Wilson 2007-08-15 16:59:35 EDT
This is in support of a feature add we've committed to for 5.1 though...

s-c-kdump support for configuring kdump on xen kernels

The attached patch implements system-config-kdump xen dump support, bringing it
on par with what we have in the kdump firstboot module.
