• How to check KVM is installed in Ubuntu Linux - Linux Shout

  KVM is an open-source virtualization technology, it falls under the Type-1 Hypervisor category. KVM stands for Kernel-based Virtual machine that is available in all modern Linux kernels as a virtualization module, it allows the Linux kernel to work as a bare metal Hypervisor. Hence, all the Linux distros whether Ubuntu, Debian, RedHat, OpenSUSE, etc. can be used as a full-fledged hypervisor system for providing virtualization. KVM works with Qemu which is another open source and free hardware emulator platform. With KVM, Qemu offers the emulation of hardware and peripherals of the system to the Guest operating system so that it can use them but the support of KVM and its direct interaction with the CPU helps the Guest OS to run almost at native speed.

  With the help of KVM, we can run multiple Virtual machines parallelly, however, make sure your Linux system’s CPU support virtualization extensions – Intel VT or AMD-V.

• How to change the drive location for GNOME Boxes VMs | TechRepublic

  Boxes is a great tool for easily spinning up virtual machines on Linux. With Boxes, you can create virtual machines from several pre-configured machines or even from your own ISO. Those VMs run smoothly and seamlessly, and can be spun up much faster than when using a tool like VirtualBox.

  But while Boxes is incredibly easy to use, it’s also not nearly as flexible as other solutions. Case in point, there isn’t even a Preferences option in the limited menu. All you can do is create virtual machines.

  That shouldn’t be a deal breaker for anyone. However, I recently ran into an issue. On my production machine, my primary drive was getting dangerously low on space. It turns out, a big part of that problem was Boxes. Why? Because Boxes stores the virtual machine files in ~/.local/share/gnome-boxes, which means it’s going to gobble up your local storage space fairly quickly. Given GNOME Boxes doesn’t have any preferences to speak of, what do you do?

• Pwndrop on Linode | Linux Journal

If you're a journalist communicating with, well, just about anyone who is trying to keep their identity secret, you might use a service like PwnDrop.

• Understanding the "fork bomb" an 11 character string that can crash Windows, Mac, or Linux machines | Boing Boing

  In this video on Dave's Garage, he discusses the "fork bomb," a DoS (denial-of-service) attack where a process replicates itself until it depletes all system resources, slowing or crashing the system. The bomb is nothing more than an 11-character program that, when entered into a Bash prompt, will replicate itself until the computer crashes.
