Решение:

1. Авторизованный пользователь должен быть добавлен в libvirtгруппу пользователей

sudo usermod -a -G libvirt $USER

2. Выполнить команды:

sudo apt install libvirt-daemon-system

sudo systemctl start libvirtd

3. Перезапустить систему.

loginctl terminate-user <user> где пользователь входит в GNOME.
sudo systemctl restart gdm
