We are using CentOS 7.1:
$ cat /etc/redhat-release CentOS Linux release 7.1.1503 (Core)
We deferred the 7.2 upgrade. It looks like it did not cause any problems so we are planning an upgrade. The wrinkle for us is:
$ uname -a Linux cryptopp 2.6.32-042stab112.15 #1 SMP Tue Oct 20 17:22:56 MSK 2015 x86_64 x86_64 x86_64 GNU/Linux
We think the 2.6 kernel is present because of hosting and an OpenVZ container. I tried to research if the CentOS QA team tested the configuration, but I could not find information on it (cf., no discussion of OpenVZ in the release notes).
Is it safe to perform the upgrade from 7.1 to 7.2 with the 2.6 kernel? That is, is this a supported configuration that will update as expected?
If not, what are our options?
