Post-installation configuration
After Phyllome OS has been successfully installed and its first-launch process completed, a few tasks are required before it can be used to its fullest potential.
As Phyllome OS evolves, the following post-installation configuration will, hopefully, be made obsolete {.is-info}
Grant the current user the ability to manage system-based 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 you connect to qemu:///system, you can add the current user to the libvirt by using the following command, in the terminal:
sudo usermod -a -G libvirt $(whoami)
Phyllome OS will eventually switch to the qemu:///session URI, which doesn't require elevated privileges. Have a look at this great blog post to understand some of the differences between the session and the system URI.

Update GRUB and reboot
Unfortunately, the GRUB config won't correctly update during the kickstart phase, so it has to be done manually.
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
When the is done, please reboot: sudo reboot
Modify the system allocated to the GPU in the BIOS/UEFI (vfio-mdev only)
Some computers allow you to modify the system memory allocated or shared with the integrated GPU, which may allow you to create more vGPUs. {.is-info}
For Intel integrated graphics cards only; rarely available on laptops computers. {.is-warning}
-
Before the host operating system boots up, you need to enter the BIOS/UEFI and to look for a setting called GPU aperture size, or GPU shared memory.
-
Use the highest possible value.
System memory will be reserved for the GPU, so make sure you have enough system memory to accomodate both the GPU and your operating system. {.is-warning}
