SSH ping etc not working between dom0 and domU''s
Hi!
I have a problem with my new Xen setup. I have installed Debian etch
with netinstall and I''m using 2.6.18-6-xen-amd64 kernel in my dom0 and
3.0.3-0-4 version xen hypervisor. I''m using four network cards on my
system and using three of them as xen bridges and dom0 is using the
fourth one only for it''s own. So basicly both of my virtual servers use
a network card

I installed 64-bit xen 3.1.0 (from xensource.com tarballs) on
three new machines today, using a configuration setup that I''ve
used successfully many times before. However, I encountered a
new problem.
These are Dell Poweredge 1950 servers, by the way.

bridge with IP address, "received packet with own address as source address"
Hi,
I''ve set up identical (what I think) machines using SLES 10 x86_64, but a new one
of those is saying frequently in /var/log/messages:
kernel: bond0: received packet with own address as source address
A short summary of ifconfig looks like this:

Weird network performance behaviour?
I'm recording TCP network throughput performance between Dom0 IP stack and all my guest domains (currently 6 running simultaneously). All guests are running simultaneously, but I only ever transmit between Dom0 and one of the DomUs while the other five are idle.
When running a netperf TCP_STREAM test (netperf on Dom0, netserver on DomU) I record the following performance numbers, CPU % as

Problem with VLANs on tg3 NICs
I have 3 machines,
T60 thinkpad with e1000 NIC
Dell PowerEdge 2950 with bnx2 NIC
HP DL360 G4P with tg3 NIC
All running xen 3.03 / 2.6.16.29-xen
I have a netbootable image with 2.6.16.29-xenU. This image when it
boots creates a vlan eth0.4002, and then tries to communicate on that
interface to a central server.
On the machines with e1000 an bnx2 NICs, this works fine. On the

So Working on CEntOS 5 I am trying to sett up Xen with 2 bridges, one that
connects dom0 and most of the domU to the physical card and the out to the
network. Got that figured out no problem, now i want to have a second
bridge that runs a local network for all the doms that doesn''t connect to
the network.
With code I have found used in multiple places I can easily get 2 bridges,

OpenSuse 10.3 - Xen 3.1.0 - VIF for DomU not recording transmitted bits correctly
I would like to track DomU bandwidth usage from Dom0 but my OpenSuse
Xen install is not tracking DomU bandwidth correctly. My DomU guests
are able to access the network and therefore the networking layer
appears to be working correctly. It just doesn''t report the traffic
correctly in ifconfig.
I am currently running OpenSuse10.3 with Xen 3.1.0_15042-51.3 running
