I monitor my main dom0 machine with ttywatch and capture the output from
any crashes on the "other" machine. I had a lot of crash problems with
FC5. Now running FC6, no crashes.
I''m assuming you''re getting a crash dump on the console and
would like
to capture that dump as text. If so, ttywatch is the ticket.

Subject: [Fedora-xen] kernel-xen crash dump analysis
After upgrading to F8 I still had a dom0 crash last night, but didn''t
catch any output. I think it''s still the null pointer dereference in
tcp_tso_segment, possibly brought to prominence by traffic shaping in a
busy domU.
I''d like to catch a crash dump the next time it happens so I can
(hopefully) intelligently report this bug somewhere.
I''m looking at

l-crash-dump-analysis/
There is no mention of Xen. I don''t see a kernel-xen-debuginfo rpm for
f8 or even f7, but there is one for f9 in rawhide it appears. Is
kernel-debuginfo sufficient even if running xen? The versions differ, so
I would imagine not.
# yum --enablerepo=fedora-debuginfo list kernel-xen-debuginfo
kernel-debuginfo
Available Packages
kernel-debuginfo.x86_64 2.6.23.1-49.fc8
updates-debuginf
# rpm -q kernel kernel-xen
kernel-2.6.23.1-49.fc8
kernel-xen-2.6.21-2950.fc8
Any advice on how capture some useful info from a crashing dom0 kernel?
