How to Install KVM on Ubuntu
If you are looking to set up a virtualized environment on your Ubuntu system, KVM (Kernel-based Virtual Machine) is a great choice. It allows you to create and run multiple virtual machines on a single physical machine. In this guide, we will walk you through the steps to install KVM on Ubuntu.
Step 1: Check Hardware Virtualization Support
Before you install KVM, you need to make sure that your CPU supports hardware virtualization. You can do this by running the following command in your terminal:
egrep -c '(vmx|svm)' /proc/cpuinfo
If the output is greater than 0, your CPU supports hardware virtualization. If not, you may need to enable it in your BIOS settings.
Step 2: Install KVM and its Dependencies
To install KVM on Ubuntu, you need to run the following command in your terminal:
sudo apt update
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
After installation, you need to add your user to the libvirt group. You can do this by running the following command:
sudo usermod -aG libvirt $USER
Step 3: Verify KVM Installation
To confirm that KVM has been installed successfully, you can run the following command:
virsh -c qemu:///system list
If you see a list of running virtual machines, it means that KVM has been installed correctly on your Ubuntu system.
Step 4: Create a New Virtual Machine
Now that KVM is installed, you can create a new virtual machine using virt-manager or virt-install. You can follow the official documentation for detailed instructions on how to create and manage virtual machines using KVM.
That’s it! You have successfully installed KVM on your Ubuntu system. You can now start creating and running virtual machines to meet your virtualization needs.
Happy virtualizing!
