[Xen-users] SuSE 9.3 domU /sbin/ifup workaround

[Robbie Dinn <robbie@xxxxxxxxxxxx>]

Hi all

I have a SuSE 9.3 domU. It has a eth0 interface, corresponding
to some vif interface in the dom0. Running

  ifup eth0

doesn't seem to work. This means I don't get any network.

It seems that /sbin/ifup relies upon /sbin/getcfg but getcfg
does not seem to find the right configuration for the eth0 device.

A attached a patch below with a work around for this. It's
only a work around, because it patches ifup, but I think the
real problem might be with getcfg.

If you want to try this patch, I suggest keeping the original
file around, like so

  mv /sbin/ifup /sbin/ifup.orig
  cp /sbin/ifup.orig /sbin/ifup
  cat patch-ifup | patch /sbin/ifup

hope that helps someone.
