This is a bug. Thanks for the report!

I now pushed a fix:
<http://cgit.freedesktop.org/systemd/systemd/commit/?id=c00524c9cc7fb498c7244350e25823b8352f078c>.

The problem was that we were not correctly truncating the machine name
(by default taken from the folder name) when using it to create a veth
link. Until the fix lands in your distro, you can simply rename your
container instance to a shorter name using the "--machine" switch to
systemd-nspawn.

Cheers,

Tom
