<pre>Running kernel 3.17.1 with system 216 (or aur/systemd-git) on an up to date
arch install.
On my physical box (grover) I use systemd-networkd to configure a bridge (br0)
and assign it ip4&6 addresses. Then start a kvm instance (host) which has the
tap interface it creates added to br0. In the kvm instance I use
systemd-networkd to add a bridge (br1) and assign it ip4&6 addresses.
At this point I tested and was able to ssh from grover to the kvm instance from
both root and a normal user to both the kvm's root and a normal user.
Then in the kvm as root I start a container (dev) using the
networkd-nspawn@.service modified adding a --network-bridge=br1 option. The
vhost0 interface in the container is setup using systemd-networkd with only an
ip6 address.
At this point the br1 interface's address is _unreachable_ from a normal user
in grover or dev. It is pingable with root in these instances.
Have I encountered a bug or it is a nasty side effect of namespaces and/or
private-network manipulated by systemd-nspawn?
Thanks
