When dom0 boots the interface is disabled
As soon as I bring the interface up (i.e. ifup eth2) the system crashes.
NO guest is running. Just dom0
Here is the kenel panic output
I have also attached the output of "dmesg" and "xm dmesg" that is executed
just after the system boots
Could you please send me the same output for your system so I can take a look
and see if I can spot anything?
Thanks
Renato
