Title:
  failed to set sndbuf on VMs network interface

Status in QEMU:
  Incomplete
Status in qemu-kvm package in Ubuntu:
  Incomplete

Bug description:
  I am trying to set "sndbuf" for a VMs network device to "0".
  I inserted to my XML file:
        <tune>
          <sndbuf>0</sndbuf>
        </tune>
  The XML file validates, but I am not able to start the virtual machine.
