Current linux kernel manual#

Manual kernel configuration Manual configuration enables the user, with some effort, to create a custom-fit kernel configuration for any system. The goal of genkernel is to help system administrators through the kernel build process. Root # emerge -search Managing the kernel Configuration Automatic kernel build genkernel is a tool used to automate the build process of the kernel and initramfs.

For users not interested in configuring their own kernel from scratch, these kernels can get things up and running quicker. These kernels come with a default configuration that should 'just work' for most systems. emerge -avuDN and the only manual step is to have the bootloader use the new kernel. Kernel updates are performed when updating the system (i.e. These kernels are compiled (if needed) and installed with just an emerge command, like any other package, which can lessen the administrative burden.

The distribution kernel project provides packages to install and manage kernels through Portage. Its stable versions follow the long term stable (LTS) kernels from upstream. When manually compiling kernel sources, or using Genkernel to automate some of the process, Gentoo recommends the sys-kernel/gentoo-sources package for most users. The sys-kernel/gentoo-kernel-bin can be kept around in case of issues booting a custom kernel. Once a system is installed and functioning correctly, a different kernel may be selected if needed. Depending on the features, some migrations are only possible between identical kernels or identical KVM versions.When starting out, the gentoo-kernel-bin provides a quick and easy way to get a kernel up and running, while still providing a light, high performance kernel - just like any modern distribution would. Support for 3.x will end in April 2016.Ī Proxmox VE cluster can manage a mixed kernel setup. The EOL Proxmox VE 3.x supported two kernel branches. Since Proxmox VE 4.2 it is based on the 4.4 LTS Linux Kernel (using the Ubuntu 16.04 LTS Xenial Kernel as a base). The first 4.0 release was based on 4.2 Linux kernel. The EOL 4.x release used latest Ubuntu 16.04 based kernel. The 4.13 received some updates after adoption of 4.15 as initially some hardware issues (NIC, SCSI) arose - those should be fixed by now, and we heavily suggest switching over to the 4.15 kernel by installing the pve-kernel-4.15 meta package - it includes, among other fixes, important security enhancements. Since Proxmox VE 5.2 it is based on the 4.15 LTS Linux Kernel (using the Ubuntu 18.04 LTS Bionic Kernel as a base). The first stable 5.0 release is based on 4.13 Linux kernel (Ubuntu 17.10 Artful). The EOL 5.x release used latest Ubuntu 18.04 based kernel. Since Proxmox VE 6.2 it is based on the 5.4 LTS Linux Kernel (using the Ubuntu 20.04 LTS Focal Kernel as a base). The first stable 6.0 release is based on 5.0 Linux kernel (Ubuntu 19.10). The EOL 6.x release uses latest Ubuntu 20.04 based kernel. The 6.2 based LTS kernel, derived from the (upcoming) Ubuntu 23.04 downstream repository, is provided as opt-in. This kernel is derived from Ubuntu 22.04, as default. The old stable 7.x release uses currently the 5.15 LTS kernel since Proxmox VE 7.2. Proxmox VE 8.1 (2023/Q4) will be based on the 6.5 kernel, derived from Ubuntu 23.10. The 6.2 kernel is derived from Ubuntu 23.04. The stable 8.x release uses currently the 6.2 kernel since Proxmox VE 8.0.
