Install KVM on Linux

Install KVM packages

Installing all packages needed to run KVM:

 sudo pacman -Syy sudo pacman -S archlinux-keyring sudo pacman -S qemu virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat
Enter fullscreen mode Exit fullscreen mode

Also install ebtables  and iptables packages:

 sudo pacman -S ebtables iptables
Enter fullscreen mode Exit fullscreen mode

Step 2: Install libguestfs 

sudo pacman -S libguestfs
Enter fullscreen mode Exit fullscreen mode

Step 3: Start KVM libvirt service 

sudo systemctl enable libvirtd.service sudo systemctl start libvirtd.service //runing ? systemctl status libvirtd.service
Enter fullscreen mode Exit fullscreen mode

Step 4: Enable normal user account to use KVM 

sudo vim /etc/libvirt/libvirtd.conf
Enter fullscreen mode Exit fullscreen mode

Set the UNIX domain socket group ownership to libvirt, (around line 85)

unix_sock_group = "libvirt"
Enter fullscreen mode Exit fullscreen mode

Set the UNIX socket permissions for the R/W socket (around line 102)

unix_sock_rw_perms = "0770"
Enter fullscreen mode Exit fullscreen mode

Add your user account to libvirt group.

sudo usermod -a -G libvirt $(whoami) newgrp libvirt
Enter fullscreen mode Exit fullscreen mode

Restart libvirt daemon.

sudo systemctl restart libvirtd.service
Enter fullscreen mode Exit fullscreen mode

Step 5: Enable Nested Virtualization (Optional)

Nested Virtualization feature enables you to run Virtual Machines inside a VM. Enable Nested virtualization for kvm_intel / kvm_amd by enabling kernel module as shown.

### Intel Processor ### sudo modprobe -r kvm_intel sudo modprobe kvm_intel nested=1 ### AMD Processor ### sudo modprobe -r kvm_amd sudo modprobe kvm_amd nested=1
Enter fullscreen mode Exit fullscreen mode

To make this configuration persistent,run:

echo "options kvm-intel nested=1" | sudo tee /etc/modprobe.d/kvm-intel.conf
Enter fullscreen mode Exit fullscreen mode

Confirm that Nested Virtualization is set to Yes:

### Intel Processor ### $ systool -m kvm_intel -v | grep nested nested = "Y" nested_early_check = "N" $ cat /sys/module/kvm_intel/parameters/nested Y ### AMD Processor ### $ systool -m kvm_amd -v | grep nested nested = "Y" nested_early_check = "N" $ cat /sys/module/kvm_amd/parameters/nested Y
Enter fullscreen mode Exit fullscreen mode

Step 6:

Run "Virtual Machine Manager"
