Using HP Serviceguard for Linux with Red Hat KVM Guests, May 2013

Technical white paper | Using HP Serviceguard for Linux with Red Hat KVM Guests

The bridge network configuration can be performed in two parts:

1. Configuring the host network

2. Configuring the guest network

Note

The below listed steps are based on Red Hat documentation, for any updates or alternatives for these steps refer to the

latest versions of “Red Hat Enterprise Linux 6 Virtualization Host Configuration and Guest Installation Guide.”

Host Network Configuration

This bridge can be created using the following steps:

1. Disable NetworkManager—NetworkManager does not support bridging. NetworkManager must be disabled to use

networking with the network scripts (located in the /etc/sysconfig/network-scripts/ directory).

# chkconfig NetworkManager off

# chkconfig network on

# service NetworkManager stop

# service network start

Note:

If you do not want to disable NetworkManager entirely, add “NM_CONTROLLED=no” to the ifcfg-* network script being

used for the bridge

2. Create a new network interface script file in “/etc/sysconfig/network-scripts/” directory with the name

“ifcfg-<device_name>” where the <device_name> must match the value of the DEVICE parameter inside the file. Its

contents are as follows:

DEVICE=bridge0

TYPE=Bridge

ONBOOT=yes

DELAY=0

NM_CONTROLLED=no

Note:

The Line TYPE=Bridge is case sensitive. It must have uppercase ‘B’ and lowercase “ridge”
