   I was starting it up with the sudo command. The problem was the fstab file. You need to add a line to /etc/fstab: (“none /proc/xen xenfs defaults 0 0“). After adding this, it worked for me but I don't know about your problem.

Did you start up xend with non-root user?

I am trying Xen with the same environment as you, that is
Ubuntu 9.10, Xen 3.4.2, and pv-ops dom0.

When I start up xend with normal user, I get similar error message:
.ERROR Internal error: Could not obtain handle on privileged command
interface (13 = Permission denied)
Traceback (most recent call last):

    xc = xen.lowlevel.xc.xc()
xen.lowlevel.xc.Error: (1, 'Internal error', 'Could not obtain handle
on privileged command interface (13 = Permission denied)')

When xend starts up with root privilege, however, I got another error.

SELinux is disabled, so it has nothing to do with security settings.
I have no idea what xend tries to connect to.

If anyone succeeded to launch xend with Ubuntu 9.10,
please let me know how to.
