[Users] CentOS 7.2 Upgrade with OpenVZ container and 2.6 kernel

[Jeffrey Walton]

Hello everyone,

We rent a CentOS 7.1 VM:

    $ cat /etc/redhat-release
    CentOS Linux release 7.1.1503 (Core)

CentOS 7.2 was released recently
(http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7) and yum is
prompting us to upgrade. In addition, its not giving us 7.1 security
updates.

We want to upgrade, but we are not sure if our configuration is
tested. The configuration includes a 2.6 kernel (not a 3.x kernel),
and we believe is due to OpenVZ container
(http://unix.stackexchange.com/q/238317):

    $ 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

We can't determine if this a supported configuration, so we are not
sure if its expected to upgrade. The release notes don't discuss it
(http://wiki.centos.org/Manuals/ReleaseNotes/CentOS7), and we could
not find information on it searching the list archives
(http://www.google.com/search?q="CentOS+7.2"+site:lists.openvz.org).

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, then what are our options?

Thanks in advance.
