[Xen-users] Network Problem in domU under OpenSUSE 10.0

Hi All,

Now that I''ve got my domU running under OpenSUSE 10.0 I have an issue
with
setting up eth0 in the domU.

The xenbr0 bridge is setup correctly in the dom0:

# mnemosyne:/etc/xen # brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              vif0.0
                                                        peth0
                                                        vif4.0

However, there is only the lo interface in domU:

xenos10:/etc/sysconfig/network # ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:13 errors:0 dropped:0 overruns:0 frame:0
          TX packets:13 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:1135 (1.1 Kb)  TX bytes:1135 (1.1 Kb)

The contents of /etc/sysconfig/network in the domU is:

xenos10:/etc/sysconfig/network # ls
.   config  if-down.d  ifcfg-lo        ifroute-lo  scripts
.  dhcp    if-up.d    ifcfg.template  providers   wireless

However, executing rcnetwork restart in the domU produces the following:


xenos10:/etc/sysconfig/network # rcnetwork restart

Is this normal?

I have tried using ifconfig eth0 192.168.0.3 up in the domU but get an error 
that the device does not exist.

I thought that a network interface would be created in the domU due to the vif 
line in the domU config file?

How can I create eth0 in the domU?

Thanks again,

Steve.

Re: [Xen-users] Network Problem in domU under OpenSUSE 10.0

I think I solved the problem.

ifconfig -a showed a lot of network interfaces, one of which, eth1, had the 
MAC address I specified in the vif line of the domU config line.  Issuing 
ifconfig eth1 192.168.0.3 up allows the domU to now ping the network.

Writing the email made me think through the problem :-)

I assume I can create an ifcfg-eth1 file in /etc/sysconfig/network in the domU 
to make eth1 come up automatically?

Thanks,

Steve.

Re: [Xen-users] Network Problem in domU under OpenSUSE 10.0

Hi

I think you have a problem with the udev-rules.
on suse-linux, the rules will give a persistent name to a mac address.

i guess you tried to install xen some times before, so that the interface 
eth0 is locked to a (now unused) mac-address (and thus your suse selected eth1 
as next free interface). 
you can release this
mac-address-to-eth-interface-mapping by editing
/etc/udev/rules.d/30-net_persistent_names.rules
and deleting the (unused) line "eth0"
_and_ the line for your eth1
in your domU.

after a reboot, the device should show as eth0 instead as of eth0, and all the
network-magic should work as expected.

regards

stefan
