I started to try to get acquainted with openvz.
Following the instructions here I installed my first ever openvz server on centos 6.
The first container I spawned was based on the ubuntu-16.04-x86_64
template.
After creation I entered it and ran:
# apt-get update && apt-get upgrade -y
The upgrade seem successful, but throws the following warning:
Which I guess is natural as Ubuntu 16.04 normally runs version 4.4 of the kernel but the container will have to make do with the version used by centos 6, which is 2.6.
What sort of trouble could one expect to run into using such a relatively outdated kernel?
