If you are running NetworkManager (the default), it's not too hard.
Here's an example

NetworkManger creates extra bonds; is this a bug?
Hi All,
I see an unexpected beahviour from NetworkManager on CentOS 7.1.
Using nmcli tool, I create a bond with two slaves as explained in the Red
Hat 7.1 Networking guide. I enable slaves and master; bond works as
expected.
When I restart NetworkManager, it creates a new bond with the same name but
not connected to any device. Two bonds with the same name is confusing for
my other monitoring

CentOS 7, systemd, NetworkMangler, oh, my
My manager tells me a system in the datacenter is down. I go down there,
and plug in a monitor-on-a-stick and keyboard. It's up, but no network. I
try systemctl restart NetworkManager several times, and ip a shows *no*
change.
Finally, I do an ifdown, followed by an ifup, and everything's wonderful.
My manager thinks that the NM daemon thinks everything's fine, and
there've been

OpenVswitch with KVM virtual machines
Hey,
I have KVM installed on my Fedora 17 box. I added the network interfaces of the virtual machines to the openvswitch bridge as follows:
____ ____
/ VM1\______br0_______/ em1\
\____/ | \____/
|
_|_
/VM2\
\____/
virbr0 is the virtual network switch
VM1 and VM2 are on the same subnet having tap interfaces vnet0 and vnet1 respectively.
em1 is the default

ifcfg-link?
This is happening with the Centos7-armv7 image 1804, but I was wondering
if it is a broader C7 issue.
My image has only 2 ifcfg files:? ifcfg-l0 and -link.? 'ip a' is listing
the ethernet as eth0.? ifcfg-link has contains:
DEVICE=link
BOOTPROTO=dhcp
ONBOOT=on
I then used nmcli to create my ifcfg-eth0
nmcli con delete eth0
nmcli con add type ethernet con-name eth0 ifname eth0 ip4

Problem with bridged network configuration
Hi,
When I initially boot my system, it fails to bring up the network.
Once booted, if I run "systemctl restart network.service", or even stop,
wait a while, then start, it starts up fine and all is well.
I'm running Fedora 19 (updated).
I followed the instructions on this page to set up a bridged network:

I note however that I did *not*

[ovs-discuss] OpenVswitch with KVM virtual machines
I am running NOX controller with a python script that prints out the

With em1 connected, all the packets that arrive at em1 are coming to the

ifname in openvz container
Hi!
Is there any way to specify ethernet device name to be created inside
the openvz container?
I could find such info at http://libvirt.org/formatdomain.html#elementsNICS.
If I do as below I get br0 as ethernet device inside VM whereas I'd like
it to be eth0.
$ cat ovz.xml
<domain type='openvz' id='144'>

Unable to get dummy interfaces to persist across reboots in CentOS 8
Have you tried to use NetworkManager ?
After all ,anything network related should be done by it.

Unable to get dummy interfaces to persist across reboots in CentOS 8
Anyone have any ideas? It's rather annoying that I can't get these to
persist across reboots without using some kind of helper script.

Unable to get dummy interfaces to persist across reboots in CentOS 8
Hello all, hoping someone can help me out here.
I cannot get dummy interfaces on a new Cent8 build to persist across reboots.
On Cent7 - this is the process I use:
Create Dummies:
# cat /etc/modules-load.d/dummy.conf
dummy
# cat /etc/modprobe.d/dummyopts.conf
options dummy numdummies=4
# ip link add dummy0 type dummy
## - repeating a/ ascending dummyN adapters for as many needed

tunnel device name acquisition?
Numerous how-tos all over the Internet show how one would set up
a tunnel using ssh, e.g.:
ssh -f -o Tunnel=ethernet <server_ip> true
I was wondering if there's a way to subsequently acquire the names
of the local and remote tun/tap interfaces (e.g., using the default
"-w any:any") for subsequent automatic tunnel configuration, e.g.:
ip link set $TapDev up
ip link set

I disagree... NetworkManager works perfectly.
