I am trying to get a network bridge to work on CentOS 6.5 on which I have used
virtual machine manager to create a KVM based CentOS 6.8 virtual instance. The parent
host has a default virtual network set up
( in virt machine manager -> edit -> network connection )
Name : Default
Device : virbr0
State: Active
AutoStart : On Boot
IPV4 Config
Network : 192.168.100.0/24
DHCP Start : 192.168.100.128
DHCP end : 192.168.100.254
Forwarding : NAT
The parent host also has the following network interfaces set up
Bridge Br0
-----------
Mac : Unknown
State : Active
Start Mode : on boot
In use by IPV4
Mode : DHCP
Address :
Slave Interfaces
eth2 ethernet
vnet0 ethernet
The configuration files for these interfaces on the parent host are as follows
pwd
/etc/sysconfig/network-scripts
cat ifcfg-br0
DEVICE="br0"
ONBOOT="yes"
TYPE="Bridge"
BOOTPROTO="dhcp"
DNS1=8.8.8.8
DNS2=8.8.4.4
STP="on"
DELAY="0"
NM_CONTROLLED=no
cat ifcfg-eth2
DEVICE=eth2
ONBOOT=yes
BRIDGE="br0"
NM_CONTROLLED=no
The ip address of the parent host is in the ip range 192.168.40.*. It
works and has access to the internet. I have also set up networking and
statically assigned an address in the 192.168.40.* range to the KVM based
virtual instance but it cannot access the internet. i.e
ping 8.8.8.8 ## fails
I have also tried assigning a static ip address to network bridge with no luck.
Im running out of ideas and looking for suggestions, can anyone advise ?
CentOS 6.5 Network Bridge SetUp With KVM Instance
Re: CentOS 6.5 Network Bridge SetUp With KVM Instance
There's just about an excuse for still running an existing 6.8 but creating a new 6.8 when 6.9 has been out for 2 months, no. And as for still running 6.5, well that's just silly. There have been so many critical security updates since 6.5 came out that it would take pages to list them. Do not run 6.5. It is dangerous. It's more than 3 years out of date.I am trying to get a network bridge to work on CentOS 6.5 on which I have used

The future appears to be RHEL or Debian. I think I'm going Debian.
