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

xen bridge script issues? - bond0 vs pbond0
Hi all,
I''ve posted a few times with regards to this error and would like to
phrase it a diff way because I have some new info.
When running my Xen kernel in conjunction with the Gitco repos and
using a mode 0 bond which is round robin, my logs fill with;
pbond0: received packet with own address as source address
When running a non Xen kernel but using the same type of mode 0

Bonds, VLANs, and Bridges on Centos 5.6
Running on Centos 5.6 with KVM...
I was wondering if anyone had any luck configuring the NICs where eth0 and eth1 are bonded together with vlan support to a bridge?
I noticed some threads show this as a possibility (http://lists.centos.org/pipermail/centos-virt/2009-November/001417.html), but haven't had any luck implementing it. There also seems to be a bug with 5.6

How to create a virtual bonded interface?
Hello,
I have a server with 4 NICS running CentOS 5.2. I have bonded the
interfaces together such that 'bond0' consists of eth0-3. This is not a
problem, and works fine.
However, I now need to create a virtual interface. In a non-bonded
server I would just create something like eth0:1, but with a bonded
interface I am a bit confused. I have created bond0:1 simple by copying

[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
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

TC not working well with bonded nics please help
Hi,
I am facing a problem when I run tc on the bonded nic cards.
When I run tc on a single nic card, it worked perfectly fine. But when I
run tc on a bond of two nics, tc gives poor performance. The two nics
were bonded in round-robin (load balancing) mode. I created a qdisc, class
and a filter as follows:
tc qdisc add dev bond0 root handle 1: htb
tc class add dev bond0 parent 1: classid

ip aliasing on bonded interface possible?
Has anyone successfully created a bonded interface (bond0) with say
two nics AND also then aliased that interface to get bond0 and bond0:1
(for an alias ip)
I just want to know if it's possible and reliable
Thanks

Badlock bad luck
Hello,
I run a CentOS 6 machine with samba, serving approx. 150 Windows users
with samba running as an NT-like PDC.
After today's samba update (samba-3.6.23-30.el6_7.x86_64 etc.), nobody
can log in.
They all get the "Trust relationship failed" error message.
If I downgrade:
yum downgrade samba-common samba-winbind samba-winbind-clients

[Bridge] Bridging over a bonded interface?
Hi,
This may sound crazy but I will go ahead anyway. Here's my scenario:
ifconfig bond0 10.10.10.1 netmask 255.0.0.0
ifenslave bond0 eth0
ifenslave bond0 eth1
brctl addbr stp0
brctl addif stp0 bond0
brctl stp stp0 on
Is this a valid scenario? I am trying to bond two interfaces and run STP
over the bonded interface..The problem I am trying to solve is to run STP

Unable to connect VMs to a bridge over bonded network on Debian 9 (works fine on Centos 7.4)
Hi,
Sorry of this is the wrong list, trying to find some help.
I am trying to set up 2 KVM hosts using Debian 9 (connecting to a 3 node
Centos 7.4 gluster cluster) To get the bandwidth I have bonded 2 NICS each
end. However while the network works fine for the Debian VM host the VM
guests cannot connect/get an IP using DHCP connecting to br0. (Same setup
on the Centos end works fine however)

I had exactly the same problem. Your workaround fixed me too.
With the new samba packages my samba\logs are full of errors.
If I temporarily disconnected the PC client NIC cable, and
logged into the domain using cached credentials, then I could
get past the problem. But, you helped me greatly with this
posting. I wasted hours checking Windows updates - useless.

Bonding modes
I have a bonded interface running in mode 1 which is active/passive and no
issue with this. I need to change it to mode 0 for active/active setup. Does
mode 0 is dependent on the switches configuration? My setup is: 2 links from
bonded interface is connected to different switches.
When I change to mode0 from mode1 , bond0 is not coming up.

bonding problem with arp-monitoring

Kickstarting bonded interfaces
Since CentOS 6.4, anaconda supports kickstarting from bonded interfaces. Has anyone managed to get this working?
Bonding modes 1, 5, 6 work fine, and they do not need any particular support on the switch. But modes 0, 2-4 are a different story, no luck here.

C6: Suspend on laptop close doesn't work
Hello,
I've been running Fedora on my Lenovo X61s laptop for many
(Fedora) generations.
Fedora 15, however, was not my cup of tea, so I've decided to wipe
out Fedora, and do a clean install of CentOS 6 (x86_64).
Everything works OK, except that the laptop does not suspend when
I close the lid.
I've checked the settings in "Power Management", and it is set

Possible bug in kickstart
Hello All,
I seem to have run into a bug with the new --bridgeslaves=<INTERFACE> option. It would seem that if I tell the bridge device to use a virtual interface (like bond0) rather than a physical interface (em1/em2) that kickstart completely barfs on it. I have provided my network section below which works fine as long as i don't enable all the bridge content.
When the
