That's what's specified in the 2 doc pages I mentioned.

I made the changes you recommend, still no bridging.
When I do
$ sudo kvm disk0.qcow2

then, on the vm
$ ifconfig

I have eth0 and lo configured, cannot reach the network.

I'm working from a minimal server install, the only
additional package is python-vm-builder.

my command is
$ sudo vmbuilder kvm ubuntu -c ubunt2vm.cfg -o

ubunt2vm.cfg:
[DEFAULT]
domain = ASHLANDCOUNTY
arch = i386
ip = 192.168.0.45
user = ubuntu	
name = ubuntu
pass = ubuntu
tmpfs = -

[ubuntu]
mirror = http://192.168.0.33:9999/ubuntu
suite = intrepid
flavour = virtual
addpkg = tree

[kvm]
libvirt = qemu:///system

/etc/vmbuilder/libvirt/libvirtxml.tmpl:
<domain type='kvm'>
  <name>$hostname</name>
  <memory>#echo $mem * 1024 #</memory>
  <vcpu>1</vcpu>
  <os>
    <type>hvm</type>
    <boot dev='hd'/>
  </os>
  <features>
    <acpi/>
  </features>
  <clock offset='utc'/>
  <on_poweroff>destroy</on_poweroff>
  <on_reboot>restart</on_reboot>
  <on_crash>destroy</on_crash>
  <devices>
    <emulator>/usr/bin/kvm</emulator>
    <interface type='bridge'>
      <source network='default'/>
      <source bridge='br0'/>
    </interface>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='-1' listen='127.0.0.1'/>
#for $disk in $disks
    <disk type='file' device='disk'>
      <source file='$disk.filename' />
      <target dev='hd$disk.devletters()' />
    </disk>
#end for
  </devices>
</domain>

Any help is appreciated.

Thanks,
Kent
