Hi all,

We have been testing OpenVZ 7 as OpenVZ 6 (legacy) will be EOL later this year.
So I have been testing it quite a bit. And I noticed something very strange.

The node which has OpenVZ 7 installed is running the following kernel:
Quote:
Linux server5000.node.com 3.10.0-957.10.1.vz7.85.17 #1 SMP Thu Apr 11 18:11:44 MSK 2019 x86_64 x86_64 x86_64 GNU/Linux


And I created an Ubuntu 18.04 container by using: vzctl create 10003 --ostemplate ubuntu-18.04-x86_64
After that I copied several things over from the /etc/vz/conf/10002.conf from a working server (made minor changes for obvious part).

When I did that I tried installing Plesk in the Ubuntu container and it worked without any issues. Cannot see errors or issues.
However when I run uname inside the container I was surprised to see higher kernel version:

Linux ns1.ubuntu1804.nl 4.15.0 #1 SMP Thu Apr 11 18:11:44 MSK 2019 x86_64 x86_64 x86_64 GNU/Linux


Remember that I come from OpenVZ 6 (legacy). Here the container had always the same kernel version as the hardware node.
Maybe something changed and the above is normal?

Can someone confirm and/or explain this please?

Thanks in advance.

Regards
