CentOS 6

Hi all,

Host - Ubuntu 12.04 64bit
VM - CentOS6
Virtualizer - VirtualBox

On reboot device br0 does not seem to be present. I must run;
# /usr/sbin/brctl addbr br0
# /usr/sbin/brctl setfd br0 0
# /usr/sbin/brctl sethello br0 0
# /usr/sbin/brctl addif br0 eth0
# service network restart

# brctl show

Code:

bridge name     bridge id               STP enabled     interfaces
br0             8000.0800277eccb9       no              eth0

Then it works

# cat /etc/sysconfig/network-scripts/ifcfg-eth0

Code:

DEVICE=eth0
BOOTPROTO=none
ONBOOT=yes
NETMASK=255.255.255.0
#IPADDR=192.168.124.10
GATEWAY=192.168.124.1
TYPE=Ethernet

# cat /etc/sysconfig/network-scripts/ifcfg-br0

Code:

DEVICE=br0
BOOTPROTO=none
#HWADDR=00:1c:c0:61:d8:b2
ONBOOT=yes
IPADDR=192.168.0.214
NETMASK=255.255.255.0
GATEWAY=192.168.0.1
TYPE=bridge
USERCTL=no
IPV6INIT=no
PEERDNS=yes

Please help. TIA

You have BOOTPROTO set to none. Perhaps you should set it to either static or dhcp depending on what you want.

Examples.

*edit*: perhaps not, centos takes different values apparently.
