similar to: Connecting ethX devices directly to a KVM/QEMU guest OS (no bridging)

Hi, I've created a bridge using 2 interfaces and have a lot of messages as follows: nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own address as source address nov 12 15:30:22 localhost kernel: br0: received packet on enp0s3 with own address as source address And the operating systems is extremely slow Interfaces files : [root at localhost ~]# cat

hello all, I have been trying to set-up bridged network with VLAN and not able to succeed as many tutorials address only single NIC. I am trying to setup 2 guests (backtrack instance) each guest has NIC1 and NIC2. following is snippet for guest1 I am not able to get 192.168.0.2 address back on guest eth0.

On my CentOS 6 partition of my laptop: First note that for this test, NetworkManager is not running because I did: chkconfig --del NetworkManager and then rebooted.

Running CentOS 5.4 x64. Have successfully bridged eth2 with br2 by following the instructions here: http://wiki.libvirt.org/page/Networking (under the RHEL section) Have been running several KVM VMs successfully via this bridge. I am now trying to bridge additional interfaces by using the same routine. Each bridge is named to correspond with the ethX device its bridged with. Example of

took a couple months off due to road blocks, hoping a fresh look would allow me to use my server as desired. I have three ports, eth0-2 over two nics. I want to bond them, and then use a bridge to connect to virtual machines on the virtual host computer. Never having done this, I am confused on some parts. Here is where I am at now and any pointers helpful. Single server, centos 6.x My issue

dear All, I'm facing this routing problem, the setup is actualy part of ltsp, but I think this problem is Centos-specific. The server is a Dell Poweredge R210. The install is standard 6.4, updated.

Hi all, I have a CentOS 5.4 server-only installation, i.e. no X installed, and for some odd reason /etc/resolve.conf gets overwritten by NetworkManager on a constant basis. I haven't been able to track down how often, but I think it's on the hour, or something. This is the conents of the file right now: # Generated by NetworkManager # No nameservers found; try putting DNS servers into

I need to allocate public IP address to two guest os. I have only 2 network card Interface on server. say eth0 and eth1. I set eth1 a public IP address. so it should in # vi /etc/sysconfig/ifcfg-eth1 DEVICE=eth1 BOOTPROTO=static HWADDR=00:1a:4d:83:ad:00 BROADCAST=202.127.29.0 IPADDR=202.127.29.5 NETMASK=255.255.255.0 NETWORK=202.127.29.0 ONBOOT=yes TYPE=Ethernet Question 1: do I have to

Hi, I have a LAN server running CentOS 5.11 with two NICs eth0 and eth1. I'd like to swap the interface names, but I don't know how to go about that under CentOS. Here's what I would do on a Slackware server (I have one next to me in my office). Open /etc/udev/rules.d/70-persistent-net.rules and edit it: # PCI device 0x8086:/sys/devices/pci0000:00/0000:00:04.0/0000:03:00.0 (e1000e)

I upgraded from CentOS 5.9 to CentOS 6.4. I try to reuse my virtual machines and am only partially successful: I can run them, I just cannot get the network OK and need some help with that. What I had in the past was pretty simple: both the host and the VM's used eth0 and each had an IP in the same subnet and could communicate freely. With the new install it seems somewhat more complex and I

Hello, I want my CentOS 6.5 computer to have a static IP. Currently I get the IP I want because I have my router assign it on the basis of mac address. I placed the following file as: /etc/sysconfig/networking-scripts/eth0 DEVICE="eth0" BOOTPROTO=static HWADDR=00:1F:D0:9E:AE:67 ONBOOT=yes TYPE=Ethernet USERCTL=no IPV6INIT=no PEERDNS=yes NETMASK=255.255.255.0 IPADDR=192.168.0.99

Weird behaviour. A couple of days ago I installed another DSL router. During the process I have somehow caused the default gw route to disappear - on system start up the interface comes up fine, I can see and connect to the local subnet but not to the internet.
