Howto KVM

check cpu virtualization support

verify if you have svm or vmx support:

grep -E 'svm|vmx' /proc/cpuinfo

verify that the kvm kernel modules are loaded:

lsmod | grep kvm

load kernel module for intel:

modprobe kvm-intel

load kernel module for amd:

modprobe kvm-amd

create bridge interface

create the bridge interface:

nmcli connection add type bridge autoconnect yes con-name br0 ifname br0

add device to bridge:

nmcli connection add type bridge-slave autoconnect yes con-name br0-eth0 ifname eth0 master br0

add ip address to bridge interface:

nmcli connection modify br0 ipv4.address 192.168.75.15 ipv4.method manual ipv4.gateway 192.168.75.1 ipv4.dns 4.2.2.1,4.2.2.2

active bridge interface:

nmcli connection up br0

install virtualization packages

using dnf install Virtualization Host group:

dnf groupinstall "Virtualization Host" -y

install virt-manager:

dnf install virt-manager -y
