[Libguestfs] supermin: failed to find a suitable kernel

Mon Nov 4 17:11:28 UTC 2019

What is the content of /boot and /lib/modules inside the container?

Also you may want to expose /dev/kvm into the container to get proper
virtualization. Otherwise you're stuck with software emulation (TCG)
which is much slower.
