Title:
  VNC working depends on command line options order

Status in QEMU:
  Expired

Bug description:
  OS: Ubuntu 10.04.2, amd64
  Pkg version: 0.12.3+noroms-0ubuntu9.5

  if -nographic option is specified before -vnc, vnc works, if vice-
  versa, it does not. I have been told (thanks, mjt), that -nographic is
  supposed to disable any graphic output, including vnc, so possibly
  it's a documentation bug:

  - kvm man page talks about -nographic disabling SDL , not VNC. While
  it might be the same to you, it was not to me and my colleagues

  - if -vnc and -nographic are conflicting, perhaps kvm should error out
  or at least warn

  - monitor console's message on "change vnc 127.0.0.1:1" command:
  "Could not start server on 127.0.0.1:1" is not helpful either

  - order of the options should not matter

  Example: (VNC works)

  /usr/bin/kvm -name ubuntu.example.com -m 3076 -smp 2 -drive
  if=virtio,file=/dev/vg0/kvm-
  ubuntu,boot=on,media=disk,cache=none,index=0 -net
  nic,vlan=0,model=virtio,macaddr=00:03:03:03:03:01 -net
  tap,ifname=kvm_ubuntu,vlan=0,script=no,downscript=no -balloon virtio
  -nographic -daemonize -vnc 127.0.0.1:1 -pidfile /var/run/kvm/1

  Example: (VNC does not work, also confuses terminal):

  /usr/bin/kvm -name ubuntu.example.com -m 3076 -smp 2 -drive
  if=virtio,file=/dev/vg0/kvm-
  ubuntu,boot=on,media=disk,cache=none,index=0 -net
  nic,vlan=0,model=virtio,macaddr=00:03:03:03:03:01 -net
  tap,ifname=kvm_ubuntu,vlan=0,script=no,downscript=no -balloon virtio
  -vnc 127.0.0.1:1 -nographic -daemonize -pidfile /var/run/kvm/1
