Description

This is a simple guide for getting started with virt-manager on Arch Linux.

Prepare the Environment¶

Make sure the system is up to date:
```
sudo pacman -Syu
```

Install libvirt and a few dependencies:
```
sudo pacman -S libvirt qemu ebtables dnsmasq bridge-utils openbsd-netcat
```
- NOTE: Extra architectures can be installed by installing the qemu-arch-extra package
```
sudo pacman -S qemu-arch-extra
```

Create the qemu user and added it to kvm group:

sudo groupadd kvm
sudo useradd -MrG kvm qemu

Edit the qemu config:
```
sudo nano /etc/libvirt/qemu.conf
```
- And set the user and groups that qemu will use:
```
user = "qemu" 
group = "kvm" 
```

Start and enable libvirtd.service at boot:

sudo systemctl enable libvirtd
sudo systemctl start libvirtd

Change the group authorized to access the RW daemon socket, create the following file:

sudo nano /etc/polkit-1/rules.d/49-org.libvirt.unix.manager.rules

And add the following:

/* Allow users in kvm group to manage the libvirt
daemon without authentication */
polkit.addRule(function(action, subject) {
    if (action.id == "org.libvirt.unix.manage" &&
        subject.isInGroup("kvm")) {
            return polkit.Result.YES;
    }
});
