PSA - ovz and ubuntu 16

blackjack4494

So right now there is a bug regarding ovz (may include kvm) and ubuntu16.
When you upgrade systemd to 229-4ubuntu21.9 the next time you restart the server there will be no ssh and a few other services may be affected too.
Last stable working systemd is 21.6

This happened to me and I had zero clue what was happening.

I made a bug on launchpad

And there are already several other bugs about it. In the bug thread you can find a way to downgrade your systemd.

I also added my own failoverssh service to be sure.

I do not know about other ubuntu versions.

I don't run systemd infected distro version with ovz. (stick to 14.04)

You can remove shitstemd from Ubuntu 16.04 though (recommended).

Well, systemd and OpenVZ 6 with its ancient kernel are not natural bedmates.
