Virtualization is a helpful technology that has exploded in popularity and accessibility in the last decade. There are many great reasons to use virtual machines, such as having a test environment separate from your host operating system. It also allows you to run multiple operating systems or Linux distros simultaneously – all inside of their own sandboxed environment, with optional network interconnectivity among your machines.

QEMU vs KVM hypervisor: What’s the difference?
Users have a lot of choices when it comes to virtualization on a Linux system. There are many use cases for virtualization, whether you want to have a test system that is isolated from your host system, test out a different Linux distribution, or even run a completely different operating system. Whatever the case may be, you will need to have a hypervisor. A hypervisor is what manages and allows you to interact with your virtual machines.
How to create snapshots of QEMU/KVM guests
KVM (Kernel-based Virtual Machine) is the virtualization solution (type 1 hypervisor) included in the Linux kernel, which, by default, is used together with QEMU, the userspace software which actually performs the guest systems emulation (type 2 hypervisor). In a previous tutorial we saw how to create and manage KVM virtual machines from the command line; in this article, instead, we will learn how to create and manage guest systems snapshots using tools like virsh and virt-manager.

VirtualBox increase disk size on Linux
In this tutorial you will learn how to increase disk size on VirtualBox. One of the great things about installing an operating system into a virtual machine is that we can easily change the machine’s CPU utilization limit, its memory usage, and the amount of hard drive space it has. With VirtualBox, all of these hardware specifications can even be changed long after the virtual machine is created.
