5 Associate the bridge with the required Solarflare PF (
HWADDDR
) in a config file in
/etc/sysconfig/network ‐ scripts/ifcfg ‐ eth4
(this example uses eth4):
DEVICE=eth4

TYPE=Ethernet

HWADDR=00:0F:53:21:00:60

BOOTPROTO=none

ONBOOT=yes

BRIDGE= br1
6 Bring up the bridge:
# service network restart
7 The bridge will be visible in the host using the
ifconfig
command:
# ifconfig ‐ a

br1 Link encap:Ethernet HWaddr 00:0F:53:21:00:60

inet6 addr: fe80::20f:53ff:fe21:60/64 Scope:Link

8 Define a network in an XML file i.e.
host ‐ network.xml
:
<network>

<name>host ‐ network</name>

<forward mode='bridge'/>

<bridge name=" br1 "/>

</network>
9 Define and start the network using
virsh net ‐ <option>
commands:
# virsh net ‐ define host ‐ network.xml

Network host ‐ network defined from host ‐ network.xml
# virsh net ‐ start host ‐ network

Network host ‐ network started
# virsh net ‐ autostart host ‐ network

Network host ‐ network marked as autostarted
# virsh net ‐ list ‐‐ all

Name State Autostart Persistent

10 On the host machine, edit the VM XML file:
# virsh edit <vmname>
11 Add the network component to the VM XML file:
<interface type='network'>

<source network='host ‐ network'/>

<model type='virtio'/>

</interface>
12 Restart the VM after editing the XML file.
# virsh start <vmname>
