I received one private reply recommending not using SuSE. However, I am
kind of sceptical here since Kurt Garloff from SuSE explicitely writes
Xen RPM's for SuSE.

However, I wrote him an email explaining the problem and to share the
gained knowledge I'll translate his German reply here:


"To make everything work with SuSE you have to set up your network as
follows:
1) choose the 'classic' way of setting up network (no 'NetworkManager'
as offered by Yast)
2) put STARTMODE of ifplugd to 'onboot' (defaults to 'on connect')
3) turn off SuSEfirewall2 or configure it properly
4) enable ip_forward (either by using Yast or sysctl.conf)"

In my case 2, 3, 4 and a reboot fixed it. I have full network of Dom0
and DomU now. I'll put Kurt Garloffs hints into the wiki on

   http://en.opensuse.org/Installing_Xen3


Thanks Kurt!
