[systemd-devel] Systemd-nspawn -- Unable to initialize virtual ethernet connection

[James Lott]

Hello!

I am trying to setup and play around with some of the private networking 
features of systemd, and one of the big thinks I'm trying to get working is 
the virtual ethernet links. For some reason though, I am unable to start a 
containder using a virtual ethernet link. My attempt is included below.

---------------------------------------
[root at utility01 ~]# systemd-nspawn --network-veth -bD /home/proxy.ddwrt01
Spawning container proxy.ddwrt01 on /home/proxy.ddwrt01.
Press ^] three times within 1s to kill container.
Failed to add netlink interface name: Invalid argument
---------------------------------------

Dropping the --network-veth option:

---------------------------------------
[root at utility01 ~]# systemd-nspawn -bD /home/proxy.ddwrt01

I'm happy to run any additional tests or provide any additional information 
needed to help try to reproduce. Thanks in advance for any help!
