[Users] sound support

[Nerijus Baliunas]

Hello,

I added a hook for sound support:

#!/usr/bin/python

#http://www.ovirt.org/wiki/Features/Serial_Console_in_CLI#Currently_operational_workaround

import os
import sys
import hooking
import traceback

try:
    domxml = hooking.read_domxml()
    devices = domxml.getElementsByTagName('devices')[0]

    sound = domxml.createElement('sound')
    sound.setAttribute('model', 'ac97')
    devices.appendChild(sound)

    address = domxml.createElement('address')
    address.setAttribute('type', 'pci')
    address.setAttribute('domain', '0x0000')
    address.setAttribute('bus', '0x00')
    address.setAttribute('slot', '0x06')
    address.setAttribute('function', '0x0')
    sound.appendChild(address)

    hooking.write_domxml(domxml)
except:
    #log to vdsm.log
    sys.stderr.write('sound: [Unexpected Error]: %s\n' % traceback.format_exc())
    sys.exit(2)

But Windows guest cannot play audio (I connect with remorte desktop connection and rdesktop),
although a driver was installed automatically in guest. Is it possible to get sound with rdesktop?

Regards,
Nerijus
