I upgraded to 2.6.18-1.2726.fc6xen. I found out the two ethernet cards
got swapped, explaining the "broken" network connectivity.
I still get the

But it seems non-fatal. I also get the warning:

But it seems to make no difference wether or not I do that.
The xenU kernel panic'ed, but continued and finished the install. and
works on reboot, wit the same issue as the host kernel. Logs of everything
follows.
Part of the kernel panics in the xen guest might have been because
"exportfs 0.0.0.0:/xen/nfs -o ro" did not give world read acecss to the
FC6test3 DVD contents, so once the guest DHCP'ed, I added a specific
export for it.
Not sure if it matters, but SElinux was disabled on the host.
