After a long break, one more try at bond/bridge nics
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,

ifconfig showing same mac for 2 nics in same bond
Hi all,
I just noticed that my two nics that are bonded via mode 0 are showing
the same mac addy in ifconfig.
Is this normal?
In syslog I keep getting;
kernel: pbond0: received packet with own address as source address
Some guidance is appreciated before I dive in and troubleshoot.
If I don't list the mac addy in my ifcfg-th# files, only one of the 2
nic comes up during boot.

bogus bond0 device showing up in /proc/net/dev
I'm running into a situation where a bogus bonded interface named
"bond0" is being created, in addition to the desired "bond2" interface.
Can anyone confirm this? Anyone know why it's happening or what I do
to get rid of it? I wanted to start my numbering scheme at 2 instead of
0, which I didn't think would be a problem.
As you can see, I have no reference

Bond & Team: RX dropped packets
Hi all,
we are testing CentOS 7 in order to migrate from Scientific Linux 6 /
CentOS 6 and we are facing an issue with the network. Trying to configure
network with teaming in activebackup mode or also with bonding in mode=1
(active backup as well) we see many RX dropped packets in the bond0
interface (around 10% of the total), 100% RX drops in the backup interface
and 0% in the active interface.

Mixed dom0/domU usage?
Hi,
I'm wondering about the impact of using both dom0 and domU's on a server at
the same time. I'm worried about the performance impact of running a Mysql
server in a domU and now I'm thinking about moving the Mysql part of a LAMP
setup into dom0 and running a few Apache guests as domUs. Since the Apaches
will serve mostly from an NFS share they won't have much impact on

again, nic driver order
I have two servers with identical hardware ... TYAN i3210w system

Broadcom NIC Binding under Centos 4.2
Hello all,
I'm having unusual difficulty configuring teaming with Centos 4.2.
The 2 NIC's are Broadcom. The HW is HP DL360 and there is no teaming
driver for RHEL4 since it comes with package (says HP).
Since there is no teaming driver from centos (as far as I know), I tried
the Broadcom Driver, configured the team file, but the team just wont
come up. A Virtual Interface should be up

lost packets - Bond
Guys, good afternoon
I'm using in my bond interfaces as active backup, in theory, should assume an
interface (or work) only when another interface is down.
But I'm just lost packets on the interface that is not being used and is generating
packet loss on bond.
What can that be?

[Advice] CentOS6 + KVM + bonding + bridging
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

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

anaconda/kickstart: bonding device not created as expected
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

ctdb: Strange behaviour after upgrade
Hi,
last weekend I've updated samba and ctdb on my 2-node cluster. Samba is
now on 3.5.6 (from 3.3.4), ctdb on 1.0.114 (from 1.0.84). Both installed
from repo via yum and ctdb-packages.
After restarting both nodes everything was fine, we could access files on
the cluster.
On monday I noticed that the nodes didn't had their initial adresses:
