[SOLVED] bridge with virtual interface

bradvan · 11-29-2017, 01:20 PM

I have a server running two subnets of 7. network on em3 and em3:0. I'm trying to install a KVM virtual server on the subnet that is associated with em3:0. I configured ifcfg-br-ex with:

Code:

DEVICE=br-ex
ONBOOT=yes
TYPE=Bridge
BOOTPROTO=none
IPADDR=7.217.207.252
PREFIX=25
STP=on
DELAY=2

and configured ifcfg-em3:0 with:

Code:

BOOTPROTO=none
TYPE=Ethernet
DEVICE=em3:0
BRIDGE=br-ex

but I can't ping anything on the 7.217.207.x network. Without the bridge it works. Anyone have any suggestions?

Thanks!

Please tell how you solved this, for future searchers. And for me

to learn from too

Thanks.

Moved the subnet that needed the virtual server to the em3 nic and the one that didn't to the em3:0 nic. I'm not sure if a bridge can only work with a physical nic or not, but this worked for me.
