@slyon Does anything here look out of the ordinary from a netplan perspective? I think this is a bug outside of cloud-init, but I'm not sure where to file it. |

This smells like systemd dependency issue to me, we can see some Can we please get the output of The |

So I tried building a Netplan integration test around it: seems to pass. But then again... Netplan's tests are calling Can we try to trace the exact sequence of services being started by systemd in this scenario? diff --git a/tests/integration/ovs.py b/tests/integration/ovs.py

@slyon , thanks for the response. Sorry for the delay; I was out on PTO last week. Here's the output requested: and
Do you know of a good way to generate this? I know of some systemd-analyze commands (e.g., plot), but I'm not sure the best thing to use. Are you looking for a runtime dependency graph? |

tests/integration_tests/bugs/test_lp1898997.py::TestInterfaceListingWithOpenvSwitch::test_ovs_member_interfaces_not_excluded is currently failing on Ubuntu Lunar under LXD VMs.
in unexpectedly returning an empty string causing the assert on the line after to fail.
The test config indicates that ovs-br interface should get a dhcp4 address, yet it is not getting one:
A journal snippet shows networkd failing to find the

and the problem that originally caused #3792 is not happening here.
tests/integration_tests/bugs/test_lp1912844.py::test_get_interfaces_by_mac_doesnt_tracebackis failing similarly. The call in the test works fine, but the interface isn't coming up so pycloudlib thinks the instance is down.Since the issue appears to be unrelated to cloud-init, I suggest we skip/xfail the tests until the root cause is fixed.
