libvirt users - Apr 2011 - PCI Pass through of atheros card

Hi,

I am trying to make a PCI passthrough of the atheros card to a VM running
over KVM. am following the steps given at
http://docs.fedoraproject.org/en-US/Fedora/13/html/Virtualization_Guide/sect-Para-virtualized_Windows_Drivers_Guide-How_SR_IOV_Libvirt_Works.html.
but am getting the following errors,


   1. Error starting domain: operation failed: failed to retrieve chardev
   info in qemu with 'info chaqdev'
   2. Details:
   3. Error starting domain: operation failed: failed to retrieve chardev
   info in qemu with 'info chaqdev'
   4.
   5. Traceback (most recent call last):
   6.   File "/usr/share/virt-manager/virtManager/asyncjob.py", line
45, in
   cb_wrapper
   7.     callback(asyncjob, *args, **kwargs)
   8.   File "/usr/share/virt-manager/virtManager/engine.py", line
959, in
   asyncfunc
   9.     vm.startup()
   10.   File "/usr/share/virt-manager/virtManager/domain.py", line
1114, in
   startup
   11.     self._backend.create()
   12.   File "/usr/lib/python2.7/site-packages/libvirt.py", line 333,
in
   create
   13.     if ret == -1: raise libvirtError ('virDomainCreate() failed',
   dom=self)
   14. libvirtError: operation failed: failed to retrieve chardev info in
   qemu with 'info chaqdev'

I am using a Dell Optiplex XE system which has VT-d enabled and Atheros
AR5001X+ Wireless Network Adapter. How do i rectify this.

Thanks,
sincerely,
Varun Ganesh
