I use vnclisten='0.0.0.0' because I'm on a private net and kind
of lazy.  But other than that, here's the config:


  kernel = "/usr/pkg/lib/xen/boot/hvmloader"
  builder='hvm'
  memory = 512
  shadow_memory = 8
  name = "openbsd"
  vif = [ 'type=ioemu, bridge=bridge0, model=ne2k_pci' ]
  disk = [
          'phy:/dev/mapper/small-vm.openbsd,xvda,w',
          'file:/xen/scratch/cd54.iso,xvdc:cdrom,r'
  ]
  device_model = '/usr/pkg/libexec/qemu-dm'
  boot="dc"

  sdl=0
  vnc = 1
  vncdisplay = 0
  vncunused = 0
  vnclisten = '0.0.0.0'
  vncpasswd=""

It's still the same problem - disconnects immediately.  I'm using
VNC Viewer for Windows version 5.1.1 (r117550).
