Setup multiple bridges for use with KVM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Running CentOS 5.4 x64.

Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section)

Have been running several KVM VMs successfully via this bridge.

I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with.

Example of ifcfg-eth0 script:
DEVICE=eth0
HWADDR=00:16:76:D6:C9:45
>BRIDGE=br0

then of ifcfg-br0 script:
DEVICE=br0
TYPE=Bridge
BOOTPROTO=dhcp
>DELAY=0

This is repeated 3 times for eth0-eth2 and br0-br2.

I've read somewhere that STP needs to be enabled when using multiple bridges. I've tried adding STP=on to the ifcfg-brX scripts but with the same result. Yes, brctl shows that STP is on.

The original bridge eth2-br2 continues to work but I can't get any traffic across any other bridge. Either by dhcp or static ips.

Is multiple bridges a possibility?

Previous to moving to KVM I was running Xen Server on the same hardware. I am just trying to recreate the network setup I had. I believe Xen Server runs on top of a linux platform so such a thing should be possible.

Thanks,

Jacob
