We do experience that issue too on CoreOS. Until CoreOS 1010, it worked just fine (systemd v225), and afterwards (systemd v229), the issue is present.
The libvirt code mentioned above did not change since 2014. Therefore, it seems that a change to systemd between 225 and 229 generates that issue. Not sure of the importance of that `Before` close there yet. I need to document myself more. We could try without it and see how it goes. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1529079 Title: Can't start virtual machines with installed systemd-container package on Xenial Status in libvirt package in Ubuntu: Triaged Status in systemd package in Ubuntu: Invalid Bug description: Can't start virtual machines after upgrade to Xenial.
