not relating to systemctl, but you should yum install yum-cron instead of manual cron
it has a nice update config, also emails you with results

I am having this exact same issue. I just downloaded the latest (02/19/2016) available CentOS 7 64-bit (minimal) template from the OVZ templates directory and created a new VM from it. Nothing special from what I can tell.

I immediately get the error:

# systemctl
Failed to get D-Bus connection: No such file or directory

The image is built on the following:
Linux 2.6.32-042stab081.3 #1 SMP Mon Sep 9 20:07:47 MSK 2013
CentOS Linux release 7.2.1511 (Core)

I am running OpenNode 6.

I am surprised that this happens right "out of the box" on this template. The template I was using before did not have this issue, but it no longer contains packages that worked and updating to the new systemd on that image absolutely breaks the whole system. I am stuck since using the latest template also seems problematic.

Please help.

Thanks,

Brandon

For posterity and others having the same issue, I am updating with research.

I found a thread (in French) in the softpedia forum on this issue. I cannot post the link because I have too few posts in this forum.

It suggests that my OpenNode kernel is too far out-of-date to support the systemd(219) running CentOS 7.2. Hopefully an update will correct that. Will report back.

Update: Unfortunately, the update didn't work, as I feared, since I'm still on OpenNode 6 (meaning CentOS 6) and the kernel updated but is still 2.6xx (apparently not good enough for systemd 219+). There still does not appear to be an OpenNode 7, so that's a bit frustrating.

I am so tired of spending months building a system, only to find just a couple of years later that it is broken due to changes and there is no upgrade path. I have spent my life basically re-building everything from scratch every few years, because things change so drastically (even though they worked fine before). If something works, they should continue to support it! /rant

I just noticed that my updated OpenNode 6 kernel is the same as my CentOS 7-minimal kernel. Strange.

I tried restarting the VM to be sure it was using the latest vzkernel, but that did not help.

Any ideas would be greatly appreciated. At this point, it seems I may be forced to downgrade to CentOS 6 VMs... a step backwards. Such a pity. I just hope that at least that works.

Ok, I think I understand the kernel version issue now.

So, my OpenNode 6 kernel is v2.6xx, which means my VZ kernel (even though CentOS 7) is limited to that kernel version.

My other CentOS 7 dedicated servers are running on the v3xx kernel.

So, OpenNode 6 simply cannot support anything that requires the v3xx kernel.

I had the same problem with CentOS 7 container and OpenVZ node with CentOS6 kernel 2.6.32-042stab108.6

The update to the latest stable OpenVZ kernel (currently 2.6.32-042stab117.14) resolved the issue.
