How to make NetworkManager NOT manage libvirtd's virtbr0 and vnet0 interfaces?

view story

http://askubuntu.com – The libvirt-bin daemon libvirtd creates virtual bridge(s) and interface(s) for the virtual machines it controls. NetworkManager kills these connections. I know that it is possible to uninstall or disable NetworkManager, but I wish to use it to manage the real interfaces on my system. I also know that it may be possible to add lines to /etc/network/interfaces; however, since libvirtd creates its interfaces dynamically, this seems a poor solution. How does one make network manager ignore all interfaces EXCEPT eth0 and wlan0? (HowTos)

I've got a laptop which I use two wireless adapters with. With one of them, I'd like NetworkManager to manage and automatically connect me to wireless networks when they're available. The other, I want NetworkManager to leave alone, letting me hack on it with iwconfig and whatnot.

I'm using Ubuntu 12.10 with Gnome 3.6 on a brand-new Samsung NP900X4C.

The installer detected the wireless adapter, took in the SSID and WPA passphrase, wrote these into /etc/network/interfaces and connected perfectly.

Once installation was finished I wanted to switch to using NetworkManager to manage the wireless adapter, since this is much more convenient than fiddling with /etc/network/interf

Good day,

I would like to ask for help in setting up bundles bridge over bonding to work with KVM. Idea is this, there are two network interfaces eth0 and eth1 on a machine that is used as a host for virtual machines.

Hi there,

I am new ubuntu user. I have tried to configure wireless usb adapter on my 9.10 desktop. Adapter did worked fine, but I have problems with wired connection now:

I can ping my router. Skype works fine (don`t need DNS), internet on virtual machine (winXP) works too.

THis is CAT of interfaces:

I have this CentOS machine with 2 interfaces.

eth0--> br0 (.10) eth1--> br1 (.11)

Although part of the same network, each interface is being fed from a different switch. I use each bridge in KVM for VMs.

All the carping examples I've seen are for two nodes one being the master or slave. In this case, I'd like my interfaces to inherit one vIP on the network, for instance .13.

I'm wondering if I've found a bug in ifupdown, but I wanted to ask here before reporting a bug:

/etc/network/if-up.d/upstart seems to fail to emit static-network-up if any virtual interfaces are defined.

I am trying to set up two virtual network interfaces on Ubuntu server 10.04.

I want to be able to have 2 hostnames resolve to my machine on my school's network.

So far as my knowledge goes, /etc/network/interfaces is supposed to contain a list of all the available interfaces. But my /etc/network/interfaces looks like this,

auto lo iface lo inet loopback

But I have a perfectly working eth0 connection. Why does not it appear here?

What is it I might be missing?

What is the correct way of configuring virtual LAN interfaces (hopefully without messing up Network Manager) on Ubuntu 12.04 Desktop?

Simply adding the interface to /etc/network/interfaces seems to cause Network Manager some confusion:

auto vlan500 iface vlan500 inet static ... ... vlan_raw_device eth1

Is there a better way of doing it?

update:

I updated /etc/NetworkManager/NetworkManager.c
