Goodbye, VirtualBox - I found a better, more reliable VM manager for Linux

General News

Summary

The author recommends switching from VirtualBox to Virt-Manager because Virt-Manager (with KVM) has proven far more reliable and offers near-native performance. The article explains that KVM is built into the Linux kernel and that Virt-Manager is a GUI front end for libvirt, making VM management easier than command-line tools. The author compares usability details—storage pools, default bridged networking, and setup trade-offs—and notes Virt-Manager has a slightly steeper learning curve but greater long-term stability. The piece also clarifies Red Hat's RHEL-specific deprecation of Virt-Manager and points out that Virt-Manager remains actively developed and easy to install on most Linux systems.
