I need to map a PCI device for a virtual machine.
The Linux distribution is Ubuntu server 9.10, infrastructure virtualization is "KVM". The virtual machine will install trixbox. To map the PCI card is a "Digium TDM410p.
There currently, KVM hosts a virtual machine that runs smoothly without any problems. In fact, this virtual machine is running Openfiler and has direct access to 2 physical disks installed on the server.
Creating a new virtual machine can not connect the Digium card, directly to the virtual machine.I tried in 2 ways.

1. Directly editing the XML file for the virtual machine with the parameters indicated in the documentation:
...
  <devices>
    <hostdev mode='subsystem' type='pci'>
      <source>
        <address bus='0x01' slot='0x00' function='0x0'/> <-----this is my personal configuration
      </ source>
    </ hostdev>
  </ devices>
  ...

2. Adding the PCI card via virt-manager

In both cases, the virtual machine will not start. Virt-manager returns this error:

"Error starting domain/ monitor socket did not show up./ Connection refused"

"Traceback (most recent call last):

File "/usr/share/virt-manager/virtManager/engine.py", line 493, in run_domain

vm.startup()

File "/usr/share/virt-manager/virtManager/domain.py", line 558, in startup

self.vm.create()

File "/usr/lib/python2.6/dist-packages/libvirt.py", line 293, in create

if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)

libvirtError: monitor socket did not show up.: Connection refused"

Can someone kindly help me?

Thanks
