Centos 7 - "Device eth1 does not seem to be present, delaying initialization".
Hi All :)
I have three servers, all with centos 7 installed 3 days ago. I need on

Multiple Internet facing Nics - Gateway issue
I have a server with 4 nics.  Two are using different internet connections,
both with static IP's, and two are connected to our private network.
The two internet facing nics seem to be battling over the gateway
designation.  Which ever I designate as the gateway the other stops
responding to incoming traffic.  I need both to listen to inbound traffic.

network interface question
Hi,
I don't have ifcfg-eth1 in my /etc/sysconfig/network-scripts. But when
I do ifconfig eth1 I can see output as below. If I do ifconfig eth12 ,
I don't see anything which i am assume is normal.

vlans+bonding+bridging
hi,
I have to configure Xen server and DomU''s which should be able 
to talk to different vlans - depending on services put on DomU''s.
I would like to enslave 2 NICs via bond interface.
Both NICs are on trunk ports which are configured in the same way, the

ethernet bridge and when using the sample instructions I have no

Nic order detection
I have a number of machines that have 4 NICs, two of which are actually 
in use, running Centos 5.  When they are rebooted, they seem to change 
the eth interface names, assigning them in different orders.  I'm a 
little fuzzy on the details because they are at a remote location and I 
can't access them easily - especially after the network breaks.  Shouldn't:
