KVM<\/strong> (Kernel-Based-Virtualization) is a Linux-based open source virtualization tool, that is used by Linux operating systems for virtualization. KVM uses hypervisor mode for the better performance of virtual machines. Hypervisor<\/strong> provides the functionality to run multiple virtual machines individually. Debian 12 has the built-in functionality to work with virtual machines. As KVM is a Linux-based virtualization tool we can use it for the management of different guest machines.<\/p>\n

This particular blog explains how you can install KVM on Debian 12.<\/p>\n

How to Install KVM on Debian 12?<\/strong><\/h2>\n

If you want to host multiple machines on a single system, you can manage with the help of KVM<\/strong>. KVM is a free kernel-based virtualization tool that provides the facility of virtualization technology. It is Linux-based and can be installed on any Linux distribution.<\/p>\n

In order to install KVM on Debian follow the commands mentioned below.<\/p>\n

Step 1: Verify Your Processor<\/strong><\/h3>\n

Before proceeding to the installation process, you check whether your processor is compatible with KVM or not. Because KVM runs only on AMD<\/strong> and Intel <\/strong>processors. Type the following command to check the processor manufacturer:<\/p>\n

# <\/span>lscpu<\/div><\/div>\n

<\/strong><\/p>\n

The command displays the specifications of the processor that is installed in the system.<\/p>\n

Step 2: Check Your Virtualization Utility is Enabled<\/strong><\/h3>\n

Check if the virtualization is enabled or not by using the following command:<\/p>\n

# <\/span>lscpu |<\/span> grep<\/span> Virtualization<\/div><\/div>\n

<\/p>\n

The command displays that the virtualization type is full. All the requirements are checked and fulfilled, we can install KVM on Debian.<\/p>\n

Step 3: Install KVM<\/strong><\/h3>\n

Type the command mentioned below in the terminal to install KVM:<\/p>\n

# <\/span>apt install<\/span> virt-manager qemu-system libvirt-daemon-system qemu-utils<\/div><\/div>\n

<\/p>\n

It will require permission to use additional disk space. Type \u201cy<\/strong>\u201d for confirmation and then press \u201cEnter<\/strong>\u201d:<\/p>\n

<\/p>\n

The above command will download and install all the necessary packages of KVM. Use the following command to confirm whether the KVM modules are installed correctly and working properly:<\/p>\n

# <\/span>lsmod<\/span> |<\/span> grep<\/span> -i<\/span> kvm<\/div><\/div>\n

<\/p>\n

The command loads the KVM modules into memory. After installation, enable and start services of KVM.<\/p>\n

Step 4: Open KVM<\/strong><\/h3>\n

Before using KVM, we start some services, that help KVM in the management of virtual machines. Type the \u201csystemctl enable –now libvirtd<\/strong>\u201d command to enable libvirt management daemon tool, which acts as a monitoring tool for different virtual machines:<\/p>\n

# <\/span>systemctl enable<\/span> --now<\/span> libvirtd<\/div><\/div>\n

<\/p>\n

 <\/p>\n

Now check libvirt status before opening the KVM, use the following command:<\/p>\n

# <\/span>systemctl status libvirtd<\/div><\/div>\n

<\/p>\n

The command shows that the libvirt service is loaded and active. Now exit the terminal, go to the Debian Desktop, and type kvm in search, KVM will be shown below:<\/p>\n

<\/p>\n

Click on the \u201cVirtual Machine Manager\u201d option and the following window will open:<\/p>\n

<\/p>\n

Click on open, it will require the password for root authentication, type your password, and click on \u201cAuthenticate<\/strong>\u201d:<\/p>\n

<\/p>\n

After root authentication, your KVM virtual management program window opens:<\/p>\n

<\/p>\n

Now you can manage different virtual machines with the help of KVM.<\/p>\n

Conclusion<\/strong><\/h2>\n

KVM <\/strong>is a kernel-based visualization tool that uses hypervisor technology in order to manage and host different virtual machines that have their own private virtual hardware resources. KVM is a Linux-based and open-source virtual machine management tool.
