Deployment KVM Guests via Cockpit Console on Manjaro KDE 21.1.2

I am posting this Howto due to currently available instructions on the Internet don't focus the user's attention on installation packages "ovmf" and "virt-viewer" on the most recent release Manjaro KDE .  Skipping mentioned packages causes issues with Remote Viewer ( Cockpit Console ) and the ability to deploy KVM guests in UEFI mode

Install KVM and Cockpit Console

$ sudo pacman -S virt-manager qemu vde2 ebtables dnsmasq \

  bridge-utils openbsd-netcat virt-viewer ovmf

$ sudo systemctl enable --now libvirtd.service

$ sudo vi /etc/libvirt/libvirtd.conf

Uncomment

#unix_sock_group = "libvirt"

#unix_sock_ro_perms = "0777"

#unix_sock_ro_perms = "0777"

$ sudo systemctl restart libvirtd.service

Cockpit console setup

$ sudo pacman -S cockpit

$ sudo systemctl enable --now cockpit.socket

Tuning firewall

$ sudo apt install firewalld

$ sudo systemctl enable --now firewalld

$ sudo firewall-cmd --add-service=cockpit --permanent

$ sudo firewall-cmd --reload
