This guide will be based on installing a Hypervisor on Debian / Ubuntu distro.
First update your system with the following command before the installation:
Update
sudo apt update && sudo apt upgrade
Start Installing a Hypervisor
Next you need to install the required packages:
sudo apt install qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils
Required services for Installing a Hypervisor
Next enable start libvirtd services:
sudo systemctl enable --now libvirtd
sudo systemctl start libvirtd
Add user
Then you need to add your user to the libvirt group:
sudo usermod -aG libvirt $USERAfter Installing a Hypervisor, Install Virt-Manager
Install Virt-Manager because you’ll use for a graphical interface create VM’s:
sudo apt install virt-manager
Install Spice
Use SPICE so your VM’s have better performance on your Linux virtual machines:
sudo apt install spice-vdagent spice-client-gtk
Reboot after Installing a Hypervisor and Virt-Manager
Restart your computer to apply the group changes and service setups.
- Launch Virt-Manager.
- Click “New VM” in Virt-Manager to begin setting up a virtual machine using KVM and QEMU.
To create virtual machines (VMs) with Virt-Manager after the above installation, start by launching Virt-Manager from your applications menu. Ensure that your hypervisor, such as QEMU with KVM, is already installed and configured correctly. Click on the “Create a new virtual machine” button to begin. You’ll be prompted to select the installation media for your guest operating system, which can be an ISO file, physical media, or a network install.
Next, specify the operating system type and version for optimal configuration. Assign the desired amount of memory (RAM) and CPU cores to the VM based on your system’s resources. Set up the virtual storage, choosing between creating a new disk image or using an existing one.
Configure SPICE for better performance of your Hypervisor
When you are setting up a Virtual Machine, enable SPICE in display settings for smoother graphics and input sharing.
After that, configure network settings by selecting a network interface, usually bridged or NAT, to provide internet access to the VM. Once all parameters are set, click “Finish” to create the VM. You can now start the virtual machine and proceed with the operating system installation, just as you would on a physical machine.
You should now have a working Hypervisor to create Virtual Machines.
