3. Find the network interface section of the configuration. This section resembles the snippet below:

4. Change the type attribute of the model element from 'rtl8139' to 'virtio'. This will change

the driver from the rtl8139 driver to the e1000 driver.

6. Restart the guest operating system.

Creating new guests using other network drivers

Alternatively, new virtualized guests can be created with a different network driver. This may be

required if you are having difficulty installing guests over a network connection. This method requires

you to have at least one virtualized guest already created (possibly installed from CD or DVD) to use

as a template.

1. Create an XML template from an existing virtualized guest (in this example, named Guest1):

# virsh dumpxml Guest1 > /tmp/guest-template.xml

2. Copy and edit the XML file and update the unique fields: virtual machine name, UUID, disk image,

MAC address, and any other unique parameters. Note that you can delete the UUID and MAC

address lines and virsh will generate a UUID and MAC address.

# cp /tmp/guest-template.xml /tmp/new-guest.xml

# vi /tmp/new-guest.xml

Add the model line in the network interface section:

3. Create the new virtual machine:

# virsh define /tmp/new-guest.xml

# virsh start new-guest
