[CentOS] OpenVZ – container based virtualization quick guide. Part 2

In this guide, we will be exploring how to use the tools which come with OpenVZ and setup a internet facing container/vm. This part of the guide also assumes you have followed part 1 to setup the container already and have a working environment.

In part 1, we setup a CentOS container which we could enter/exit but we didn’t do anything else on the network. What we want to do is set it up so we have the ability to bridge our hosts’ network and define static IP for network interface.

yum install bridge-utils


[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0

# Broadcom Corporation NetXtreme BCM5761 Gigabit Ethernet PCIe

DEVICE=eth0

ONBOOT=yes

BRIDGE=bridge0
[[email protected] ~]# cat /etc/sysconfig/network-scripts/ifcfg-bridge0

DEVICE=bridge0

TYPE=Bridge

BOOTPROTO=dhcp

ONBOOT=yes

DHCP_HOSTNAME="tooncent.com"
/etc/init.d/network restart
[[email protected] ~]# cat ifcfg-veth101.0

# Broadcom Corporation NetXtreme BCM5761 Gigabit Ethernet PCIe

DEVICE=veth101.0

ONBOOT=yes

BRIDGE=bridge0

vzctl set 101 --netif_add eth0 --save echo ' DEVICE=eth0 ONBOOT=yes BOOTPROTO=dhcp ' > /vz/private/101/etc/sysconfig/network-scripts/ifcfg-eth0
