Prerequisites
Follow the instructions at the IVS Installation Guide to get IVS installed and running.
Installation
Install the packages required for virtualbox
| Code Block |
|---|
sudo apt-get install virtualbox-4.2 |
Create a TAP interface for each virtual machine that will be running on the host. The following command creates 8 interfaces numbered veth0 to veth7.
| Code Block |
|---|
for tap in `seq 0 7`; do sudo ip tuntap add mode tap veth$tap; sudo ip link set veth$tap up; done |
Edit /etc/rc.local to automatically create the TAP interfaces at startup.
| Code Block |
|---|
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
for tap in `seq 0 7`; do sudo ip tuntap add mode tap veth$tap; sudo ip link set veth$tap up; done
/etc/init.d/xenon restart
exit 0
|
Modify the IVS configuration file /etc/default/ivs to include the virtual interfaces.
| Code Block |
|---|
# Default to connecting to a local OpenFlow controller
DAEMON_ARGS="-c 127.0.0.1:6633 -i veth0 -i veth1 -i veth2 -i veth3 -i veth4 -i veth5 -i veth6 -i veth7"
|
Restart xenon to apply the changes
| Code Block |
|---|
sudo restart xenon
|
To connect a virtual machine to the Xenon switch, go to the network configuration under Machine->Settings->Network, select Bridged Adapter, and then choose one of the veth interfaces.
