Maybe you can use netconsole...

Just my 2 cents!

My machine has Suse 11 and 16 VM's with Red hat 5.3.under heavy load the
dom0 freezes, and the VM's of course are inaccessible. How do I troubleshoot
this? I enabled kdump, but don't know how to trigger a dump, since PRTSCR
only triggers a screen capture. Is there anything that I can do to find out
what is failing? Novell found that I has packet loss, but that does not make
a system freeze. How do I capture a memory dump if the machine is frozen?
