Xen users - Nov 2005 - Dom0 eth0 has different MAC address than expected, ignoring

Hi,

I''m a newbie to Xen and I need some help. I saw user
''datto'' had a similar
problem but changed to FC4 to resolve it.

I''m currently running FC3 and Xen2.0.7. I did the usual ''make
install'' and I
can boot into Xen dom0.  However, my network card is not working. The driver 
is found in the linux-2.6.11.12-xen0 tree but not selected. I rebuilt the 
kernel by compiling the Marvel Yukon/SysKonnect SK98xx driver both in the 
kernel and as a module but to no avail.

So the error message I have is
"Device eth0 has different MAC address than expected, ignoring."

If I remove the MAC address completely either using the GUI or under 
/etc/sysconfig/network-scripts/ifcfg-eth0 and 
/etc/sysconfig/networking/ifcfg-eth0 (HWADDR), and I try to re-activate the 
network card, I get the message "sk98lin device eth0 does not seem to be 
present, delaying initialization."

I also tried using a MAC like AA:00:00:0E:1A:DF but still have the same 
"different MAC" message.

I don''t think it''s a driver problem since the kernel has the
driver listed
in the .config file.  Any help would be most appreciated.

Thanks!

-Ian

What does the output of dmesg say? Does you see an eth0 there? 

I take it if you modprobe the module when compiled as a module, it
doesn''t succeed?

If the eth0 driver is being loaded as a module, please compile it into
the kernel.

This should solve the problem.

In my understanding this messages comes when interfece is initialised and
/etc/sysconfig/network-scripts/ifcfg-ethX does have HWADDR set there and
it''s different. Easy test would be to comment HWADDR out.

Hi,

Thanks for your help. Sorry for the late reply. I have been trying out other 
stuff in setting up Xen. The hardware interface did have the HWADDR there 
but could somehow not be initialized.

Although the driver seemed to be in the kernel configuration already, I 
decided to re-patch the driver with a patch I used 5 months ago. Now the 
network interface can be initialized properly, i.e. gets the static IP 
addresses that the host used to get, the default gateway etc. but I still 
can''t get out (can''t ping anyone on my LAN or anyone outside).

But yeah, the "Dom0 eth0 has different MAC..." is fixed. Thanks!
