After Phyllome OS [has been successfully installed](/deploy/install) and [the first-launch process has been completed](/deploy/install#first-launch), a few tasks are required before it can be used to its fullest potential.
> As Phyllome OS evolves, one of the main goal is to shorten the time it would take for an end-user to have a fully operational virtual machine loaded with the installer of their favorite operating system, to the point that a user may not see the Phyllome OS environnement at all.
### Grant the current user the ability to manage virtual machines
Any new user, including the one that has been created during the first-launch set up, won't be part of the `libvirt` group. It means that it won't be able to manage the *qemu:///system*, which runs `libvirt` as root.
To avoid a password prompt each time the Virtual Machine Manager is launched, you can add the current user to the `libvirt` by using the following command, in the terminal:
```
sudo usermod -a -G libvirt $(whoami)
```
> A known bug affects the terminal: extra spaces between letters. To solve it, click on the burger menu (three stacked horizontal lines) then go to *Preferences > Profiles > Unnamed* and check the box called *Custom font*.

### Run a few scripts
During the installation process, a few scripts got fetched. They need to be run to further customize Phyllome OS.
