similar to: 802.3ad + Centos 6 + KVM (bridging)

Hi all, Read many posts on the subject. Using 802.3ad. Few problems; Cannot ping some hosts on the network, they are all up. Cannot resolve via DNS which is one of the hosts that I cannot ping, internal nor external DNS hosts. Unplugging the NICS and plugging them back in will then not allow pining if the default d=gateway. When cold booting it somewhat works, some hosts are pingable while

Hi all, Does any one have 802.3ad (mode 4) working on there Centos6 KVM setup? Of course we are also bridging here. - aurf

Hi, Wondering if this is the proper bridging technique to use for Centos6+KVM; http://wiki.centos.org/HowTos/KVM Before I embark on this again, I would like to do it by the book. Thanks in advance, - aurf

With the current talk on bonding, I have a few questions of my own. I'm setting up a KVM host with CentOS 6.3 x86_64 on which I'd like to attach the VMs to a bonded interface. My target setup is one where two GigE NICs are bonded and then the KVM bridge interface is attached to the bonded interface. Initially I tried to use the balance-alb mode (mode6), but had little luck (receiving

Trying to think this through, hope someone can lend a hand. I have 3 eths I want to bond together and that seems simple enough. eth0,1,2 <-> bond0 , though not sure how this would be for multiple ip addresses needed for the virtual machines... perhaps eth:0, eth:1 etc....to bond0:1, bond0:2 ? then I want to bridge to my virtual machines.... I am going to be using virtual machines, each

Hi, We have a Dell server with 4 Ethernet interface. I would to aggregate them in a bond. Everything work but the default gateway doesn?t work on the ? bond0 ? interface and I have no links. My configuration: - CentOS 7: :/etc/sysconfig/network-scripts# uname -a Linux nas-mtd2 3.10.0-957.5.1.el7.x86_64 #1 SMP Fri Feb 1 14:54:57 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux - NetworkManager disabled:

Hi, may be someone has an idea: We have three supermicron servers with two 10Gb Ports each, connected to a cisco switch stack 1Gb ports. All are on auto speed. I configured a LACP bond on both sides on all servers, first with citrix xen server. On one server eth0 goes down from time to time ? maybe within minutes, someday it is up for some hours. Two server are fine; the bond is up for 24

Greetings all. This has been an ongoing issue for me for a few months, and I''ve been trying to get an answer. My server has two NICs, and I want to set up the following: NICs (x2) -> bond (mode 5) -> Xen Bridge -> Doms ...however, trying to configure this doesn''t seem to work: network-bridge steals eth0 instead of bond0, which breaks the bond AND my networking. The

Hi all, Just wondering if any one has experienced problems with trying to bridge a bonded interface with your KVM guests? There may be some ARP issues as per this link; https://bugzilla.redhat.com/show_bug.cgi?id=584872 Thanks in advance, - aurf

Hi! I just upgraded a machine to 7.7.1908 and the default route is not being set on boot. This particular server has a bonded interface, and the corresponding configuration for the master is ( /etc/sysconfig/network-scripts/ifcfg-bond0): TYPE=Bond BOOTPROTO=none DEFROUTE=yes IPV4_FAILURE_FATAL=yes NAME=bond0 DEVICE=bond0 ONBOOT=yes IPADDR=10.3.20.131 PREFIX=24

Hi, I've using linux bonding in active-backup mode to combine two pairs of GigE NICs (eth0/eth1, eth2/eth3) into two logical bonds (bond0/bond1). All is working fine. However, I would like to specify a primary interface for each bond. This means I need to specify different options to the bonding module for each bond. I have tried every conceivable incantation of options and cannot get the

Hi all, i have a xen 4.3 installation and would like to have a bridge bond szenario: *** eth0 eth1 | | bond0 | br0 | vif = [ ''bridge=br0,mac=xx:xx:xx:xx:xx:xx'' ] *** With the network script in debian wheezy *** /etc/network/interfaces auto bond0 iface bond0 inet manual slaves eth0 eth1

I have a machine I just deployed w/ tg3 interfaces, I have setup bonding on this same line of server (HP DL380 G4) a million times. I saw there were changes recently to how you configure a bond and have my setup configured according to: http://kbase.redhat.com/faq/docs/DOC-7431 The HP switch has a LACP trunk defined on the two ports. Problem is, when rebooting, I need to issue a `service network

Hi all, I've setup a ethernet bond on my centos 5.6 server , when i do a reboot the bond does come up but cleared all the slaves and i've to manually re-add them with ifenslave. does anyone know a solution to this? am i missing something? offcourse i can add it to my rc.local but there must be a more elegant way. please see my configs below Thanks, Wessel ifcfg-bond0: DEVICE=bond0

Hi, I am currently struggling with the right way to configure a bonding device via kickstart (via PXE). I am installing servers which have "eno" network interfaces. Instead of the expected bonding device with two active slaves (bonding mode is balance-alb), I get a bonding device with only one active slave and an independent, non-bonded network device. Also the bonding device
