=== Networking ===

The default network starts off as being inactive, you must enable it before it is accessible.

This can be done by running the following command:

This can be done by running the following command (may require sudo):

<code>virsh net-start default</code>

By default this will enable the <code>virbr0</code> virtual network bridge.

The default Video may not allow different resolutions, `Virtio` will allow for more.

~~error: failed to get network 'default'~~

~~error: Network not found: no network with matching name 'default'~~

=== Shared folders ===

To be able to share a folder with a guest, you will need 'virtiofsd'. The recommended way to solve this problem is now to add <code>pkgs.virtiofsd</code> to <code>virtualisation.libvirtd.qemu.vhostUserPackages</code>:

virtualisation.libvirtd = {

enable = true;

qemu.vhostUserPackages = with pkgs; [ virtiofsd ];

};
