Description John D. Ramsdell 2006-05-08 07:53:44 EDT
I did a yum update on Friday, and now xend fails to start.  I've had no problems
with Xen previously, and installed it using the instructions on the
virtualization project page.

[root@goo ramsdell]# /usr/sbin/xm list
Error: Error connecting to xend: Connection refused.  Is xend running?
[root@goo ramsdell]# /usr/sbin/xend start
ERROR: Could not obtain handle on privileged command interface (2 = No such file
or directory)

Opps.  I boot the wrong kernel when I generated the above message.  When the
right kernel is booted, I cannot CD to /var/run/xenstored.  Here is a corrected
transcript:

Add... /var/run/xenstored is present, a xend restart produces output in
/var/log/xend.log:
