kernel 2.6.16 20060410 smp
and xen unstable hg tree from 20060410

xm info says changeset: unavailable

Well, I found out that this might me a ipxripd problem. The IPX routing daemon 
started by accident, and flooded my network.

But the other Problem I have with this machine is, that when I run a make -j3 
in dom0, the domUs are very slow, even if there is only one domU.

Any ideas?
