Hi all,
I'm a little bit confused about networking in Centos 7: I've copied my bridge setup from a Centos 6 for KVM networking to Centos 7. I changed the interface name to the new schema and I had expect that it would work.
But:
The Bridges didn't came up with the following log message:
"Error: Device 'br61' is waiting for slaves before proceeding with activation"
Config:
DEVICE=br61 ONBOOT=yes TYPE=Bridge BOOTPROTO=none DELAY=3 STP=yes NM_CONTROLLED="no"
Some more messages from the same type for other bridges. Sounds like a dependency problem.
The bridges were created but they all were in state "down". The physical vlan tagged interfaces were not created, which should be bridged to those bridges above.
Playing with STP and Delay didn't help.
Because I saw no error, I removed the NetworkManager and it worked.
Now when I reboot the system doesn't exit the SSH daemon before removing network interface so you end up in a hanging SSH connection. Ok, minor problem.
Does somebody have similar dependency problems?
Best Regards Oli

A small correction: NM_CONTROLLED was not set in my first setup. I've added that later to make the bridge setup work.
