I am using the Yocto project to build my kernel/distro for my VMs, since that is what we use on our hardware. Here is the output from those commands:

My guess, per Matthias next email in the thread, is that IPv6 is required, which I believe is not built into my kernel. I'll see about adding that and try again.
Yes, this looks like the problem and this is why I've asked for the output. The excellent answer from Matthias should be enough to fix your setup :)
Kind regards, Sven
