  • How To Use Vagrant with Libvirt on Linux to manage VMs

    Vagrant is an open-source software product for building and maintaining portable virtual software development environments; e.g., for VirtualBox, KVM, Hyper-V, Docker containers, VMware, and AWS. It is not a stand-alone virtualization provider. It relies on other virtualization providers such as Virtualbox, Libvirt/KVM, Docker, VMWare to create and run virtual machines.

    By default, Vagrant uses Oracle VirtualBox as provider. If more than one providers are installed (E.g. Virtualbox and Libvirt) in your system, it will always start a VM with Virtualbox unless you explicitly provide a specific provider. One of the great features of Vagrant is that users are never tied to a specific virtualization platform. The users can create workflows that work with multiple virtualization providers.

    In this guide, we will learn how to use Vagrant with Libvirt KVM provider on Linux.

5 Top Free and Open Source Erlang Web Frameworks

One of the types of software that’s important for a web developer is the web framework. A framework “is a code library that makes a developer’s life easier when building reliable, scalable, and maintainable web applications” by providing reusable code or extensions for common operations. By saving development time, developers can concentrate on application logic rather than mundane elements. A web framework offers the developer a choice about how to solve a specific problem. By using a framework, a developer lets the framework control portions of their application. While it’s perfectly possible to code a web application without using a framework, it’s more practical to use one. Read more
