supermin: kernel: SUPERMIN_KERNEL environment variable /boot/uImage
supermin: failed to find a suitable kernel (host_cpu=powerpc64).

I looked for kernels in /boot and modules in /lib/modules.

If this is a Xen guest, and you only have Xen domU kernels
installed, try installing a fullvirt kernel (only for
supermin use, you shouldn't boot the Xen guest with it).
