similar to: 2 or more bridges not working

I had a major HD failure and need to rebuild my host server and the virtual servers that resided on it. I am moving from CentOS 5.6 to CentOS 6.3. I am using the same configuration, as best as I can tell, that was working only hours ago on 5.6 but does not work on 6.3. My guest server can see network traffic on the bridged network device but I cannot seem to interact with it. Iptables turned

We just went to replace the bridge/firewall services one one server with the same on another. It's pretty simple, and I literally cloned (w/ rsync) a third server that does this onto the one that will be the new one. Then copied the /etc/sysconfig/iptables from the one being replaced, and brought it up this morning. Nope. We had to put everything back the way it was. The new one sees the two

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

Hello. I desire to get bridge network working using virt-manager. Centos 7 and centos 7 guest. >From researching I think I need to have a ifcfg-br0 file like this ? cat ifcfg-br0 DEVICE=nm-bridge0 STP=no TYPE=Bridge BOOTPROTO=none IPADDR=192.168.1.8 PREFIX=32 GATEWAY=192.168.1.1 IPV6INIT=no NAME=br0 ONBOOT=yes DELAY=0 Is that for sure needed ?

Hi all, I use CentOS5.x + Xen in production for virtualization. I use it with bridged vlan networks and bonding (active-backup) like that: eth0 eth1 | | ------- | bond0-------bond0.10---------bond0.12 ... | | | | vlanbr10 vlanbr12 dom0 | | ------------- -------------- | |

Requirement is a very strong word , but you should consider using it and here is a short demo why: - By default, RHEL uses NetworkManager to configure and manage network connections, and the /usr/sbin/ifup and /usr/sbin/ifdown scripts use NetworkManager to process ifcfg files in the /etc/sysconfig/network-scripts/ directory. [root at system ~]# ls -l /usr/sbin/ifup lrwxrwxrwx. 1 root root 22 21

Then after a few ours, the second ip > address reappears. That's really interesting. Doesn't NetworkManager also store other settings in a different location, not the ifcfg files? I think it does so and

Hi, I'm trying to configure a network bridge over a bonding without any success. Here is my configuration: ifcfg-eth0: DEVICE=eth0 HWADDR=00:1E:C9:E8:3F:E5 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-eth1: DEVICE=eth1 HWADDR=00:1E:C9:E8:3F:E7 ONBOOT=yes USERCTL=no MASTER=bond0 SLAVE=yes ifcfg-bond0: DEVICE=bond0 ONBOOT=yes BRIDGE=br0 USERCTL=no ifcfg-bridge0: DEVICE=br0

If you'd like to extend that a little bit, here's example configs on how to do LACP and vlan tagging on c6: host network-scripts # cat ifcfg-eth0 DEVICE=eth0 ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no MTU=1500 MASTER=bond0 SLAVE=yes host network-scripts # cat ifcfg-eth1 DEVICE=eth1 ONBOOT=yes USEERCTL=no BOOTPROTO=none IPV6INIT=no MTU=1500 MASTER=bond0 SLAVE=yes host

Hello, I?m trying to configure a CentOS 7 server to act as a host for a bunch of virtual servers (KVM). I have an 802.3ad bonded Ethernet connected to the server with a bunch of tagged VLANs. I want to be able to build a bridge interface on the server for each VLAN and then attach that to the bond interface and the virtual clients. I also want to attach a host interface to one of the VLANs

I''ve been using Puppet now for a month or so and I''ve come to a problem that may warrant an additional Puppet metaparameter. I''m advocating the addition of a metaparameter called "preaction" (or something like that), which will perform some arbitrary action before the resource is modified. There may be a way to do this within Puppet already (with some

Hi, I encountered a problem when creating a VLAN interface according to the Red_Hat_Enterprise_Linux-7-Networking_Guide. I configuered the parent interface ifcfg-eno1 as follows: DEVICE=eno1 TYPE=Ethernet BOOTPROTO=none ONBOOT=yes And I created a new file named ifcfg-eno1.5, the content is: DEVICE=eno1.5 BOOTPROTO=none ONBOOT=yes IPADDR=192.168.81.3 PREFIX=24
