As requested this is the output inside my container: root@ead989650980:/# ls /boot androidboot efi grubinitrd.img-core initrd.img-core-0.7.43+ppa27 uboot root@ead989650980:/# ls /lib/modules 4.15.0-66-generic I know, that there is no kernel inside /boot, but to my understanding this is a normal behavior of docker and I can not just install a kernel inside the container.

/dev/kvm is already mounted inside this container. Thanks Klaas > -----Ursprüngliche Nachricht----- > Von: Tomáš Golembiovský <tgolembi(a)redhat.com&gt; > Gesendet: Montag, 4.
