FIX?

# GNS3 -> Preferences -> Qemu -> General settings -> uncheck Use KVM where available.
apt install qemu-kvm qemu-system-x86 libvirt-daemon-system libvirt-clients bridge-utils

sudo usermod -aG kvm $USER
sudo usermod -aG libvirt $USER
sudo usermod -aG kvm $USER

sudo usermod -aG kvm gns3
sudo usermod -aG libvirt gns3
sudo usermod -aG kvm gns3

reboot
# GNS3 -> Preferences -> Qemu -> General settings -> check Use KVM where available.
