Install Virtual Machine Manager(libvirt) in Manjaro 

STEP 1: Launch Terminal and enter the following command to install KVM and necessary dependencies.

sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq bridge-utils openbsd-netcat
STEP 2: The next two steps are very important and often ignored by many users. Make sure to complete it else, you will get error “adduser: The group `libvirtd’ does not exist” when you run the Virtual Machine Manager after installation is complete!

Enable the service by entering the below command:

sudo systemctl enable libvirtd.service
STEP 3: Start the service using below command:

sudo systemctl start libvirtd.service

sudo groupadd --system libvirt
sudo usermod -a -G libvirt $(whoami)
newgrp libvirt
//Verify that user is added to libvirt group.
id $(whoami)

Open the file /etc/libvirt/libvirtd.conf for editing.

sudo vim /etc/libvirt/libvirtd.conf
Set the UNIX domain socket group ownership to libvirt, (around line 100)
unix_sock_group = "libvirt"
Set the UNIX socket permissions for the R/W socket (around line 102)

unix_sock_rw_perms = "0770"
Restart libvirt daemon after making the change.

sudo systemctl restart libvirtd.service
