[Bug 591489] Re: QEMU_AUDIO_DRV set to none by libvirtd in Lucid

[Victor J. Orlikowski]

Certainly, but the complaint about sound not working for guests applies to *all*
guests on the machine that have a VNC console. I have pasted a guest configuration
that is a representative example.

The guest configuration file is named:
/etc/libvirt/qemu/windows7.xml

Its contents are:

<domain type='kvm'>
  <name>windows7</name>
  <uuid>a522d67b-7a31-0163-04d5-e97816dd7000</uuid>

  <currentMemory>524288</currentMemory>
  <vcpu>1</vcpu>

    </interface>
    <serial type='pty'>
      <target port='0'/>
    </serial>
    <console type='pty'>
      <target port='0'/>
    </console>
    <input type='tablet' bus='usb'/>
    <input type='mouse' bus='ps2'/>
    <graphics type='vnc' port='-1' autoport='yes' listen='127.0.0.1' keymap='en-us'/>
    <sound model='ac97'/>
    <video>
      <model type='vga' vram='9216' heads='1'/>
    </video>
  </devices>
</domain>

When I check the log (/var/log/libvirt/qemu/windows7.log) corresponding to this virtual machine, I see:
LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin QEMU_

What concerns me, is that QEMU_AUDIO_DRV is set to "none", with no
action on my part.
