The file should get installed if you installed Xen from sources.
I think it doesn't get installed if you install Xen from the DemoCD,
but it's on the CD at (/usr)/local/src/xeno-1.2/install/etc/netbsd.
I'm also attaching the file to this email, just in case.

def config_usage ():
The config file '%s' requires the following variable to be defined:
vmid -- Numeric identifier for the new domain, used to calculate
the VM's IP address and root partition. E.g. -Dvmid=1
Additionally the following variable may be defined:
image -- Path to kernel image, can be gzip'ed. [/boot/netbsd]
mem -- Memory size. 
name -- Domain name. [NetBSD VM vmid]
ip -- Primary IP address for domain. [this domain's IP + vmid]
nfsserv -- NFS server IP address. [169.254.1.0]
nfsroot -- Path to nfs root filesystem. [/netboot/netbsd]
