Sorry, I did not see the mail from Bruce earlier. Here are the terminal outputs you asked for, Bruce.

I can see from the last output that xenfs is a module. How do I mount it?

Cheers!

Hey Guys!

Need some help here... I am trying to install Xen4.0.1 on Ubuntu
10.04.1 LTS (64 bits) which has the kernel version 2.6.32.24-generic.
I followed this tutorial for the installation, using the configuration
file uploaded by Thiogo, which is actually meant for kernel version
2.6.32.18.

The kernel compilation steps go through smoothly, except that when I
enable the xend and the xend domain services using the update-rc.d
command I get the same warning message as NunziaG84

update-rc.d xend defaults 20 21

the output was:
update-rc.d: warning: xend start runlevel arguments (2 3 4 5) do not match LSB
Default-Start values (3 4 5)
update-rc.d: warning: xend stop runlevel arguments (0 1 6) do not match LSB
Default-Stop values (0 1 2 6)

And then when I reboot the machine, xend does not start. On issuing
the command /etc/init.d/xend start, or status, there is no terminal
output.
When I type in "xend start" directly, I get the following error message:

sudo xend start

Possibly missing drivers related to hotplug issues?

Can you post the output from lsmod?

What does  cat /proc/misc show?

Also grep XEN /boot/config-<whatever kernel you're running>

I see that several other people here are facing similar issues. Could
anyone throw some light on what the matter might be, and how one could
move towards resolving it.
Does anyone have a configuration file for my specific xen and host
operating system kernel versions. Actually I am confused as to whether
the kernel version of the .config file has to match that of our Xen
download or our host operating system....



Thanks!!!!

Maybe, who knows.

Does it start if you execute "/etc/init.d/xend start" manually?
