Whereas in Ubuntu: $ sudo apt-get install qemu-kvm qemu virt-manager virt-viewer libvirt-bin libvirt-dev
In CentOS you will need the following packages: # yum install qemu-kvm libvirt libvirt-client virt-install virt-viewer To begin, let’s install the necessary tools. While you may continue without them, performance will be negatively impacted. No output means the extensions are either not available or not enabled in the BIOS. To do that, use the following command, where vmx and svm are the virtualization flags on Intel and AMD processors, respectively: # grep -color -E 'vmx|svm' /proc/cpuinfo CPU Extensionsīefore we proceed, we need to check if the virtualization extensions are enabled on our CPU(s).

In this article we will list the necessary tools to manage and configure both in Linux systems.įor many decades, virtualization has helped IT professionals to reduce operational costs and increase energy savings. Virtualization and containers are hot topics in today’s IT industry.
