KernelCare announced today that it now provides automated kernel security updates without reboots for Proxmox VE 3.x and the newly released Proxmox VE 4.x versions. Proxmox VE is used by nearly 100,000 hosts and more than 5,000 commercial customers in over 140 countries. It is a powerful and efficient server virtualization management solution, and with KernelCare, Proxmox servers now get timely, important patches while servers remain online. KernelCare also simplifies the life of administrators by allowing them to avoid complicated planning of internally and externally coordinated downtime events, manually rebooting servers in the middle of the night or on weekends.

KernelCare team consistently checks for security updates by monitoring security mailing lists and Proxmox VE repositories to ensure that all security patches are addressed, freeing administrators from the need to monitor security lists. As soon as any vulnerabilities in Proxmox kernels are discovered, KernelCare Linux and security experts adopt specific patches to fix those vulnerabilities. Once those patches are built and tested, they are deployed to KernelCare patch servers, from where they are automatically delivered to Proxmox VE servers running KernelCare. The agent on Proxmox VE servers controls deployment of those patches making sure that running kernel is fully secured. The process is fully automated and removes the need for a reboot, all while boosting security, reliability, and uptime.

"KernelCare supports most popular Linux distributions, and we have just added support for Proxmox VE, which included backported critical bug fixes and features to ensure utmost kernel security,” said Igor Seletskiy, CEO of KernelCare and CloudLinux. "For example, recently we back-ported support for Debian 8 and systemd 220+ for older Proxmox 3.x kernels."

KernelCare is very easy to install and takes only a few minutes with a single command, still without a reboot.

The company offers a free 30-day trial of KernelCare, and there is no limit on the number of servers trial license can run on. More information is available at
