An Introduction to Ubuntu Multipass: Simplifying Virtual Machine Management

Ubuntu Multipass is a lightweight, easy-to-use tool that helps users create and manage virtual machines (VMs) with ease. It allows you to quickly launch Ubuntu instances on your local machine without the need for complex setup or configuration of virtualization software. Multipass is available on multiple platforms including Windows, macOS, and Linux, making it versatile and accessible to a wide range of users. With just a few simple commands, you can create Ubuntu VMs in seconds, making it ideal for developers, testers, or anyone who needs to work in isolated environments. Multipass automatically handles the installation and configuration of virtual machines, which makes it faster and more efficient for users to run Ubuntu environments.

Recovering from Btrfs Boot Failures Using GUI Tools on Fedora

By the end of this guide the reader will be able to identify a Btrfs‑based Fedora installation, boot from a live USB, list and restore snapshots using the graphical utilities btrfs‑assistant and snapper, and verify that the system returns to a functional state without resorting to the command line. Understanding the Btrfs Layout Used by Fedora Fedora Workstation and Fedora KDE install the root filesystem as a single Btrfs partition that contains two default sub‑volumes. One sub‑volume holds the traditional “/” hierarchy, while the second is dedicated to /var/lib/machines . The latter exists to keep container images out of snapshot operations; it remains empty on systems that do not run virtual machines. Because Btrfs stores data in sub‑volumes rather than separate partitions, a snapshot captures the state of an entire sub‑volume at a point in time. The installer (Anaconda) automatically registers these sub‑volumes with the snapper service. Snapper maintains a series of read‑only ...
