This guide will cover the full installation of KVM hypervisor and its management tools on  Fedora 29 and Fedora 28. KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux Systems running on x86 hardware with virtualization extensions (Intel VT or AMD-V).

KVM consists of a loadable kernel module,kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.

Install KVM on Fedora 29 / Fedora 28

In this section, we’ll cover all the steps to install the latest release of KVM hypervisor on Fedora 29 / Fedora 28. We’ll also include the installation of management tools like libguestfs-tools

Step 1: Ensure your CPU has Intel VT or AMD-V Virtualization extensions

The first step is to confirm that your CPU has either Intel VT or AMD-V Virtualization extensions. In some systems, this is disabled on BIOS and you may need to enable it.

$ cat /proc/cpuinfo | egrep "vmx|svm"

Step 2: Install KVM / QEMU on Fedora 29 / Fedora 28

Install required virtualization packages on your Fedora 29 or Fedora 28 system by running:

sudo dnf -y install bridge-utils libvirt virt-install qemu-kvm

After installation, verify that Kernel modules are loaded

lsmod | grep kvm
kvm_intel 233472 0
kvm 737280 1 kvm_intel

Also install useful tools for virtual machine management.

sudo dnf -y install virt-top libguestfs-tools

We have a guide on how to use libguestfs-tools like:

Step 3: Start and enable KVM daemon

By default, KVM daemon libvirtd is not started, start the service using the command:

sudo systemctl start libvirtd

Then enable the service to start on boot

sudo systemctl enable libvirtd

Step 4: Install Virtual machine Manager GUI

If you have a Desktop version of Fedora, you can install virt-manager which gives users a GUI interface to manage your Virtual Machines.

sudo dnf -y install virt-manager

Step 5: Create a test instance

First start by creating a bridge network to be attached to your instances, below guides should help.

Once you have your bridge interface ready, create a test instance using CLI or Virtual Machine Manager.

virt-install \
--name fed29 \
--ram 1024 \
--vcpus 1 \
--disk path=/var/lib/libvirt/images/fed29.img,size=20 \
--os-variant fedora29 \
--os-type linux \
--network bridge=br0 \
--graphics none \
--console pty,target_type=serial \
--location 'http://fedora.inode.at/releases/29/Server/x86_64/os/' \
--extra-args 'console=ttyS0,115200n8 serial'

The installation is on text mode but the procedure of installation is similar to GUI. After finishing the installation, reboot the instance and login

Fedora 29 (Server Edition)
Kernel 4.18.16-300.fc29.x86_64 on an x86_64 (ttyS0)

Web console: https://localhost:9090/ or

localhost login:

You can also login through console:

$ virsh console fed29

Press <ENTER> key on getting:

Escape character is ^]

See our Virsh Commands cheat sheet for a complete list of virsh commands.

For installation through Virtual Machine Manager GUI, you may need to configure virt-manager as a non-root user on Linux
