Install KVM to Arch Linux

So KVM is a very efficient type 1 hypervisor, it is free and it comes with all the power of the linux community and of Open Source Software. Arch is a very lightweight distro and very customizeable, people tend to prefer “stabler distro” such as debian or centos but in fact Arch is pretty stable and has the latest cutting edges technology, and no big update only rolling update no release updates.

Check Hardware compatibility

Ssh into your server so you verify that the CPU of your server can run Virtual Machines.

egrep --color=auto 'vmx|svm|0xc0f' /proc/cpuinfo

Install the needed packages

pacman -S openbsd-netcat  qemu libvirt dnsmasq qemu-arch-extra firewalld qemu-block-iscsi qemu-block-rbd qemu-block-gluster qemu-guest-agent

Then edit that file so that libvirt daemon is launch as root.

vim /etc/libvirt/qemu.conf

Add :

user = "root"
group = "root"

Remove the previous group line they are irrelevant.

Start the Services

Use systemd command line controller called systemctl to restart the 2 services.

systemctl restart firewall libvirtd

Make the services start at boot

systemctl enable firewalld libvirtd

Connection to Kvm over ssh

We are now making your local computer connect to kvm hypervisor via ssh.

SSH config

Make a ssh folder :

mkdir ~/.ssh

Then create the config file.

vim ~/.ssh/config

Then you can edit and add for example :

Host The_Name # EMail, kubernetes, whatever..
    Hostname IP_ADDRESS
    Port ThePortNumber
    User TheUser
    IdentityFile ~/.ssh/YourPrivateKey

For more information:


Download and install virt-manager, it is in the repository.

Start Virt-Manager and go File > Add Connection


Then fill in with what you put in ~/.ssh/config


And then you can create Virtual machine on your server, just download ISOs to “/var/lib/libvirt/”.
