           Summary: systemd-networkd assertion failure with Xen vif
        QA Contact: systemd-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: steven at uplinklabs.net
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: general
           Product: systemd

I've got a Xen domU running with systemd 213, set up to use systemd-networkd
for initializing networking at boot time. Networking never comes up. journalctl
shows that systemd-networkd had an assertion failure:

systemd[1]: Starting Network Service...
systemd-networkd[29143]:             eth0: gained carrier
systemd-networkd[29143]:             eth0: DHCPv4 address 10.0.8.120/19 via
10.0.0.1
systemd-networkd[29143]: [69B blob data]
systemd-networkd[29143]: Assertion 'link->manager->rtnl' failed at
src/network/networkd-address.c:241, function address_configure(). Aborting.
systemd[1]: Started Network Service.
systemd[1]: systemd-networkd.service: main process exited, code=dumped,
status=6/ABRT
systemd[1]: Unit systemd-networkd.service entered failed state.
systemd[1]: systemd-networkd.service has no holdoff time, scheduling restart.


Installed a build of the same systemd revision with debug symbols (compiled
with -O0 -ggdb, split debug symbols) and reproduced the issue. Here's the
backtrace:

Any ideas or further information needed?
