KernelCare supports many distributions, but does it work with your kernel?

KernelCare supports many distributions, but does it work with your kernel?

We often get a question whether a particular kernel is supported by KernelCare. We support a large number of distributions and kernel versions, such as CentOS/RHEL/CL 5,6 & 7, Debian, Ubuntu, Virtuozzo & Proxmox VE. List of all supported distributions, kernels, as well as patches for them is available at http://patches.kernelcare.com.

Yet, to simplify the process, we have released a simple script that you can run on your server to find out for sure.

https://github.com/iseletsk/kernelchecker/blob/master/py/kc-compat.py

It can be executed by running:

curl -s https://raw.githubusercontent.com/iseletsk/kernelchecker/master/py/kc-compat.py|python

Or ...

wget -qq -O - https://raw.githubusercontent.com/iseletsk/kernelchecker/master/py/kc-compat.py|python

The script will respond with:

  • COMPATIBLE -> kernel supported by KernelCare
  • UNSUPPORTED -> KernelCare doesn’t recognize the kernel
  • UNSUPPORTED; INSIDE CONTAINER -> running inside the container, unable to patch kernel

The version you have is 3.16.0.x
The earliest we support is 3.16.7
sorry

Actually - you are right, it should be supported, let me try/double check.

Please, try now, small bug in the script was causing it.

Nice that also Debian 8 is supported.
But not so nice, that the 4.9 Debian Jessie-backports kernel were missing

Perhaps that can be improved because 4.x kernels have much better SSD/filesystem
support/performance and you already offer such kernels for other vendors?

Hi!
The support of such kernels will be available in one week.
Thanks!

Hi,

pretty that now also Debian 9 / 4.9.x kernels are supported but still Debian 8 Backports 4.9 ones are missing
And since the networking/firewall handling was totally modified it would take longer time to adopt setup from Debian Jessie to Debian Stretch so this request still makes sense ...

Thx

Hi, I have 3.10.0-614.10.2.lve1.4.72 and have just purchased KC after a trial. The trial did not warn that the Kernel was not supported. Can you please advise

I received the below error when i tried to install kernelcare

Error: kernelcare conflicts with uptrack-1.2.41-0.el6.noarch
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Hi.
I'm with OVH on a dedicated server, and I think it's a custom kernel. Can you add support to it?

Unfortunately KC does not support OVH's kernels. Some providers allow booting with vanilla kernels (e.g. CentOS) which can be a solution for the problem.

Hi,

what about 4.14.15-xxxx-std-ipv6-64 ? will you support it soon ?

I am with Sercured Servers in Arizona and after a recent Yum Update that upgraded my Apache kernel I am suddenly receiving emails that say:
Unknown Kernel (CentOS 2.6.32-754.6.3.el6.x86_64)

When I run your script it says I am UNSUPPORTED. Is this an error on your end, or is there a change with my server hosting company?

A stub for this kernel is expected by Oct 16
