Dedicated and VPS Kernel Upgrades


For cPanel notifications such as the following example, stating that the server's kernel is out of date, please refer to the information below associated with your package type.

Sample notification:

The current kernel version is out of date. running kernel: 2.6.32-642.13.1, most recent kernel: 2.6.32-642.13.2
Update the system’s software by running ’yum update’ from the command line and reboot the system.

Dedicated hosting

Our Dedicated servers have KernelCare installed, which provides live patches for the Linux kernel on the server to address known security issues, but cPanel does not detect it.

While KernelCare protects our Dedicated hosting customers, it does not require server reboot as it is a "rebootless" Linux patching. The newest kernel gets installed automatically as the primary kernel as soon as CentOS releases it.

If there's any issue while updating the kernel, please contact us via phone or chat for assistance.

VPS hosting

As of April 13, 2021, we upgraded our VPS platform to a Kernel-based Virtual Machine (KVM). KernelCare protects this platform. It is a more modern, open-source virtualization technology built into Linux. Our legacy platform, Virtuozzo (VZ), was outdated. Moving to KVM for all new VPS packages will provide more control, updated tooling, and the ability to use more current operating systems in the future. All packages from this date will be provisioned on the Kernel-based Virtual Machine (KVM) platform. 

Rebooting a VPS will not update the kernel version. Please contact our Support team via phone or chat if you have concerns with the kernel version running on your VPS.
