Resolved | peth1: received packet with own address as source address
If you get a lot of those messages and you don''t want them:
peth1: received packet with own address as source address
or
peth0: received packet with own address as source address
This is the way I found to solve this problem on Debian maybe someone can
post more information about other distribution like suse or redhat...
This problem will occur if you have more than one dom0 on your

Arp Flip Flops make machine inaccessible.
CentOS 5.5 Xen "standard" Xen Installation.
I have two nics. I just put the second one to DHCP and modified the

were sequential IP Addrs on same subnet.
arpwatch has indicated flip flips. I can find no rhyme or reason to
predict them. I know I missed I must have missed a step somewhere.

XEN Virtualization & Isolation of Guest using ebtables
Hello,
The basic details of my host and XEN configuration and network configuration
all appear below.
Whilst I have come this far, a lot of it has been intuitive so I now have
plenty of questions. Firstly I would like some help and clarification with
regard to ebtables and especially how it works in a Virtualized environment

Hello everyone.
I just installed Xen 3.0.3 in a debian etch box.

network issue, RHEL4, lack of peth0/peth1 device
Hi! I''m not new to Xen but I''m new to this list. I''m having a truely bizarre problem with Xen bridged networking at the moment. This is a new install, on RHEL4. The symptom is that any domU set up simply fails to talk to anything else. It''s there, and running, and it has an ethernet device, but there''s never any response.

Re: pv_ops kernel and network problems (checksumoffloading?)
Hi,
I found this mail about network problems in the archive.
I think I have the same network problems with a routing (with or without
NAT) domU connected by two network bridges.
The dom0 logs thousands of following messages:
--
Attempting to checksum a non-TCP/UDP packet, dropping a protocol 1 packet
--
and all outgoing TCP packets have wrong TCP checksums (traced on another

Server with 2 Nics (continuation)
Hi *.*,
This is a continuation on the 2 NICs thread after some more testing.
Just to remember my goal.

I want to create a domU with 2 virtual NICS. One of them will contact
the outside world, the other one will contact a VPN. No reason in
concrete for choosing the bridging protocol, only because its the
default one. I installed the dom0 with the 2 NICs active, with

xen 3.4.3 on CentOS 5.5 dom0: multiple nic issue -- eth1 won''t restart
Hi Folks:
I have a strange problem with multiple (2) NICs on a CentOS 5.5 dom0
setup running xen 3.4.3 and have been struggling to fix it for some
time. I could not find anything by googling or searching through this
list but that is probably because I couldn''t figure out the correct
search terms.

Could not setup Speed and Duplex on CentOS 5.5
Greetings,
I recently installed CentOS 5 on Dell PE 1750 server. I have noticed that
the speed and duplex settings are 100 Half Duplex. I tried to change the
duplex settings to full, but no success. I got the error message "Cannot get
current device settings: Operation not supported". Does anyone else
experience this issue?. Below is the error message and some more details
about my box.

You can have multiple vethX interfaces on recent builds -- see netback/loopback.c.
I think the current default is a rather miserly 1 (and should be increased), but can be set on the command line.

network-bridge fails to copy from eth0
I''ve just installed Xen on a new CentOS 5.1 system, and I can''t seem
to make xenbr0 connect to the network. This system has a single
physical network card. Apart from creating a few DomU guests, I have
not changed any of the configuration.
After running network-bridge, xenbr0 and friends are created, but the
address and routing info is not moved.

network-routing
Dear Xen-Users,
I use Xen 3.1.0_15042 on my OpenSuSE-10.3-computer. Without starting the
xen-kernel I can connect my second computer via my native computer to
the internet. After starting the xen-kernel the xen-bridge came
automatically up.
How can I configure the xen-bridge or the xen-devices?
I get routing problems:

When I install xen via yum, using virt-manager to build a machine, I
was displayed no options for Shared Physical Device. Here is a pic,
just for show http://imgur.com/HiPiY
Then, I did yum downgrade xen, got no network options at all. Do I
need to restart something or run a script? I want to use peth0.

Xen Dom0 network fails to start at boot
I have a server running Centos 5.2 as a Xen host. A problem that's
shown up recently is that at boot, the dom0 interface eth0 doesn't come
up properly, with the result that the host is only accessible via remote
console. If I execute 'service network restart', eth0 comes up
normally, with an IP address and the correct routing.

xen hotplug scripts not working
Hello Everyone,
I have set up a xen server with 10 physical network devices using the bridge mode of XEN. This is because I want to split and separate the network traffic for security reasons. Maybe the best way is to use pci back hide. But I want to understand what is going on here.
For all testings I have only activated eth[0-3].
My first tests were successful. I have created a VM using
