[Xen-users] SuSE 10 no network in dom0 - arp problem?

Hello.
I have installed the SuSE Linux 10 XEN kernel but no domU yet. Now I  
cannot ping to and from dom0. I get lots of ARP broadcasts from dom0  
but dom0 seems to ignore ARP answers. When pinging to dom0 it ignores  
arp requests. This happens regardless xend is running or not. This  
happens in the xen kernel only, when booting stock kernel all works  
as expected.

What can I do?

Robert

AW: [Xen-users] SuSE 10 no network in dom0 - arp problem?

Are you using the default network script shipped with xen ?

What''s the configuration of your network bridge ? What say brctl ?

Re: AW: [Xen-users] SuSE 10 no network in dom0 - arp problem?

xend suddenly refuses to set up the peth0 etc. I do a clean install now.

I will be back here later in some hours.

Thank you very much,
Robert Welz

Re: AW: [Xen-users] SuSE 10 no network in dom0 - arp problem?

brctl show
bridge name               bridge id                     STP  
enabled          interfaces
xenbr0                         8000.feffffffffff              
no                             vif0.0
                                                                         
                                     peth0

shouldn''t xenbr0 be bound to eth0?

Robert,
I''ll jump in here because I''ve had similar problems and, by  
explaining my reasoning, I will hopefully be corrected if I am wrong.

I believe that the answer is "NO".
Given the recent (on the Unix timeline) ability to rename devices,  
you should look at the overall dom-net architecture rather than the  
names.

peth0 is the (renamed) physical I/O device and it is bound to the  
virtual "hub" xenbr0.
We also attach to that bridge one xen net device "vifX.0" where X is  
the domain number.
The other end of that xen net device is called "eth0" in each of the  
respective domains.

dom0 is handled just like the various domU. An application sends a  
packet via "eth0". Xen causes that packet to appear on vif0.0 which  
is bound to xenbr0. Therefore the packet is replicated on peth0 and  
appears on the actual wire.

As I see it, the arp difficulty is a result of the fct that they have  
"moved" the real MAC address from peth0 to eth0. I think that the xen
net device acts as a ppp cross-connect and does not pass arp since it  
doesn''t need arp to establish routing since there is just one device  
on the other end of the (virtual) wire.

RE: [Xen-users] SuSE 10 no network in dom0 - arp problem?

On my System eth0 is connected to the bridge and working. Maybe there is the
Problem. On my Debiansystem I needed to add following line at the beginning
of the network script:
/etc/xen/scripts/network:
#!/bin/sh
#
...
#
LANG="C"
...

The Problem above corrected above, is that your locale changes the output
from ifconfig. 
The title of the MAC Address is so changed from HWaddr -> Hardware Addresse.
The network script parses the output of ifconfig for HWaddr and so
don''t
find the right entry.

Thanks. Now I now why it does''t work.

Will that work if I give peth0 its own ip address and configure my  
route gateway through peth0?


So in which way is xen 3.0 in SuSE 10 usable then?
- DomU''s cannot be installed since install source must be network  
based (NFS or the like). NFS doesn''t work because I have no network.
- No softwareupgrade for Dom0. Obviously if no network ...

The change from xen 2.0 to xen 3.0 fixed some problems, my serial  
ports work now for my USV but introduced the network issue.

Is there another distro except SuSE which has a working xen 3.0 ?  
Whats about debian?

Robert

Re: [Xen-users] SuSE 10 no network in dom0 - arp problem?

Perhaps you should have a look on:
http://www.suse.de/~garloff/linux/xen/RPMs-100/

There is a newer Xen3 build for SUSE 10.0. It should solve your netwerk
problems.

Dito!

We''ve played only with the latest kernel in the Xen workshop with Kurt,
Ian, Keir and Gerd (thanks to all four!) at Linux-Kongress in Hamburg, 
which Kurt has built directly during the workshop.
Maybe the old rpm was broken!

And everything was fine with SuSE-10.0 as Dom0 and DomU!

I tried build 7398, 7313, 7267 and 6715 without success. No network,  
no serial ports.
