QA:Testcase Virtualization KVM PCI Device Assignment assign using libvirt

Description

This case verifies that a PCI device can be assigned to a KVM guest and used successfully in the guest.

How to test

• Edit an existing guest's configuration using virsh edit
• In the devices section add a hostdev element describing the device using its PCI address

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <source>
        <address bus='0x00' slot='0x19' function='0x00'/>
      </source>
    </hostdev>

• Start the guest using virsh start
• Try using the device in the guest - e.g. if it is a NIC, bring it up and ping a remote host
• Shut down the guest
• Check that the device can be used in the host again

Expected Results

• The guest should start without any errors
• The device should be usable within the guest
• When the guest has been shut down, the device should be usable in the host
