What am I doing wrong?

[eric%cirr.com@localhost (Eric Schnoebelen)]

I'm trying to bring up my first domU on a system..

The host is a SUN X2200-M2, which amusingly enough won't boot a
GENERIC kernel, but runs just fine under the xen hypervisor. The
system is running:

        NetBSD egsner.cirr.com 4.99.67 NetBSD 4.99.67 (XEN3_DOM0) #12: Fri Jun 
27 13:54:02 CDT 2008  
eric@duke:/home/eric/work/eric/NetBSD-current/obj/amd64/sys/arch/amd64/compile/XEN3_DOM0
 amd64

The userland is a few revs older:

        /sbin/init: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), for 
NetBSD 4.99.55, dynamically linked (uses shared libs), not stripped

xen tools are:
        xenkernel3-3.1.4
        xentools3-3.1.4

When I try to start my domU (which is a clone of an older
machine, and going to run a i386 kernel) I get the following
message:

        egsner-> sudo xm create -c /usr/pkg/etc/xen/egsner-i386 
        Using config file "/usr/pkg/etc/xen/egsner-i386".
        Error: [Errno 2] No such file or directory: '/proc/xen/balloon'


No directory /proc/xen exists on my system.  A /kern/xen does,
but it doesn't have a balloon file.

The configuration file I am using is:

        # all the comments have been stripped.
        kernel = "/boot.d/xen-kernels/netbsd-4.0-i386"
        memory = 1024
        name = "egsner-i386"
        vif = [ 'mac=00:16:3e:00:00:11, bridge=bridge0' ]
        disk = [ 'phy:/dev/wd1a,0x1,w' ]

With all of the above, what am I doing wrong to get the error
from xm??  

What additional information is needed to help get this working?

Thank you,
        Eric
