I have a very similar issue with systemd-219, but with a MUCH more plain-jane desktop network config. I have systemd network-device-renaming turned off here, so have only the standard eth0 and lo networks. The critical bit, however, appears to be that I'm IPv4 *ONLY*, no IPv6 configured in the kernel. Looking at your reported network settings, I see only IPv4 there also, and STRONGLY suspect it's the same problem. Here's my /etc/systemd/eth0.network: [Match] Name=eth0 [Network] Address=192.168.1.2/24 Gateway=192.168.1.1 That was originally it, and it worked with systemd-218 (including the -rNs). Note that the addresses are IPv4, and there's nothing there about IPv6. But here's what systemd-networkd (319) returned for networkd status (reformatted a bit for posting): eth0: Cannot configure IPv6 forwarding for interface: no such file or directory eth0: could not bring up interface: Address family not supported by protocol eth0: could not setup route: Network is unreachable eth0: link configured But it wasn't... IPv4 was apparently not even tried. When 219 failed to bring up the network, based on the errors in the log I tried adding this to the [Network] section also, to no avail (tho back on 218-r3 it doesn't hurt, either): DHCP=no IPForward=no In the systemd.network manpage, those settings have IPv6 options, and with particularly IPv6 forwarding obviously being attempted in the log, I thought maybe specifically disabling them might convince networkd to quit trying IPv6 and try IPv4. Unfortunately... So after looking around a bit more to see if I could figure out some other way to tell systemd to disable IPv6 and try IPv4 only, without success, I downgraded (binpkg) to systemd-218-r3, restarted systemd (systemctl daemon-reexec) and the various services lib_users said were using stale libs, and sure enough, with 218-r3, networking came right back up. So check your systemctl status systemd-networkd, and see if the logged messages it spits out look like they're trying IPv6 only on an IPv4 only configured network, as mine did. If so, it's the same breakage, and it's definitely NOT VM related or limited as it's my physical machine acting up here, no VMs at all. If it's different breakage then I'll have to file a new bug, but given that your network config was IPv4 only also, I strongly suspect it's the same problem. While 219 may do IPv4 along with IPv6, it appears to have problems if IPv6 isn't configured at all, and won't start IPv4 either in that case, at least for static IP assignments (IPv4 DHCP may still work). In which case, bad upstream bug! Also, assuming it appears to be the same bug for you, you may consider setting critical importance, since it kills IPv4-only networking, and most boxes are pretty broken without networking! Duncan
systemd 219 needs explicity define in [Network] section 'IPForward=yes'
