[CentOS] Centos 7 and Network/Bridges

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
