Xen users - Dec 2009 - Mysterious crash on SLES11; VMs did not autostart

I have a couple sles11 servers running xen 3.4:

A little while ago I had a mysterious crash. Nothing
in /var/log/messages except that the server coming back up. That''s the
first problem that I guess I''ll have to keep an eye on. If it happened
once I assume it will happen again.

Second problem is that none of the domUs automatically started, even
though they are set to. If I do an xm list -l [dumU_name] they are set
to start with:
(on_xend_start start)

If I run virt-manager and look at the details of the domU it shows they
are set for auto start. 

*xend and xendomains are also set to start and looks like they did.
*dom0 is set with dom0_mem=2048M
*ballooning is disabled

Any ideas or suggestions on either issue?

Thanks,
James
