Description

This test case verifies that Xen DomU networking works correctly, including the ability to attach/detach network devices.

How to test

From the dom0, attach a new virbr0 type interface to the rawhide domU
```
$> virsh attach-interface rawhide bridge virbr0
```
Inside the guest, run
```
$> ifconfig
```
You should be able to see it.
Trying pinging the gateway from it
```
$> ping -I eth? -c 2 192.168.122.1 
```
From the dom0, disconnect the interface from the rawhide guest
```
$> virsh detach-interface rawhide bridge
```
Download this File:Xen-domu-attach-nics.sh script to the dom0, and make it executable with chmod +x Xen-domu-attach-nics.sh. This shell script attempts to attach 40 network devices. Run it with
```
Xen-domu-attach-nics.sh
```
and see how many attached, there should probably be at least 16 to "pass" this test.

When you are finished, run

$> Xen-domu-attach-nics.sh rawhide remove

to clean up.

The network devices should be presented to the domU on attach-interface, and removed from the guest on detach-interface.
The rawhide guest should be able to use the network interfaces.
