I have xen 3.0.3.  After a reboot, xend won't come up.

[root@test ~]# xm list
Error: Unable to connect to xend: No such file or directory. Is xend running?
[root@test ~]# service xend start
[root@test ~]# xm list
Error: Unable to connect to xend: No such file or directory. Is xend running?


I'm seeing this in xend.log:

This is in xend-debug.log:

This is in /proc/xen:
