--- title: Get started with Phyllome OS description: published: true date: 2021-11-23T15:53:10.242Z tags: editor: markdown dateCreated: 2021-11-13T11:37:31.498Z --- # How to use Phyllome OS *This section explains how to further configure Phyllome OS, and how to deploy your favorite operating system within it.* ## Post-installation configuration After Phyllome OS [has been successfully installed](/deploy/install) and [its first-launch process 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. {.is-info} > The following post-instalaltion configuration will, hopefully, be made obsolete in a future Phyllome OS version. {.is-info} ### 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 (the three stacked horizontal lines) then go to *Preferences > Profiles > Unnamed* and check the box called *Custom font*. {.is-warning} > Phyllome OS will eventually switch to the *qemu:///session* URI, which doesn't require elevated privileges. Have a look at [this great blog post](https://blog.wikichoon.com/2016/01/qemusystem-vs-qemusession.html) to understand some of the differences between the *session* and the *system* URI. {.is-info} ### Run a few scripts During the installation process, [a few scripts are fetched](https://github.com/PhyllomeOS/phyllomeos/tree/main/post) and stored under the `/usr/sbin` directory. They need to be run to further customize Phyllome OS. #### Desktop enhancements The following script will change the desktop background and pick opinionated defaults for the Virtual Machine Manager. It will also add a new User session URI for the Virtual Machine Manager. Open the terminal and run the following script as a regular user: ``` /usr/sbin/configure-vmm-and-desktop.sh ``` *The updated desktop background. Notice that there is now a new URI called QEMU/KVM User session* ![post-install-conf-1.png](/post-launch/post-install-conf-1.png) #### Create and run a virtual machine without any attached disk The following script, which also doesn't require root privileges, will create a virtual machine called `my-first-live-vm`. This virtual machine will be started automatically and added to `virt-manager`. ``` /usr/sbin/create-live-vm.sh ``` *Notice the new icon under QEMU/KVM: this is the new virtual machine that has just been created. Go to the section to learn how to interact with it.* ![post-install-conf-2.png](/post-launch/post-install-conf-2.png) ## Access your virtual machine display * Double-click on *my-first-live-vm* to open its virtual display, then click on *Connect to console*. ![post-install-conf-3.png](/post-launch/post-install-conf-3.png) > Phyllome OS ships with a small ISO crafted by the team behind [netboot.xyz](https://netboot.xyz/), and that can do network boot, allowing it to do network-based installations of the most popular Linux distributions, among other niceties. {.is-info} ![post-install-conf-11.png](/post-launch/post-install-conf-11.png) * After a few seconds, you will be greeted by the following screen. ![post-install-conf-4.png](/post-launch/post-install-conf-4.png) * Under the menu, go to *View* and select *Full Screen* ![post-install-conf-5.png](/post-launch/post-install-conf-5.png) * Go to *Live CDs* > There is no disk attached to this virtual machine. As a result, only Live CDs will work out-the-box. {.is-info} ![post-install-conf-10.png](/post-launch/post-install-conf-10.png) * Scroll down this list ![post-install-conf-13.png](/post-launch/post-install-conf-13.png) * Stop at *Tiny Core Linux* and press Enter ![post-install-conf-14.png](/post-launch/post-install-conf-14.png) * Select *Tiny Core Linux x86_64* ![post-install-conf-15.png](/post-launch/post-install-conf-15.png) * Select *Tiny Core Linux CorePure* ![post-install-conf-16.png](/post-launch/post-install-conf-16.png) * Enjoy your disposable virtual machine ![post-install-conf-6.png](/post-launch/post-install-conf-6.png) When you are done messing around, input the following, and you will be back in Phyllome OS ``` sudo poweroff ``` > That's it, congratulations! {.is-success} --- *Are you looking for tasks to do with your system?
