Hi Rich
Kindly ignore my previos mail.
I have downloaded the latest version of supermin supermin-5.1.8 and have
compiled it for powerpc.Moreover there was no need to patch the src/
kernel.ml file as the changes were already implemented on the latest
version.
But still when i run libguestfs-test-tool on powerpc ubuntu,I get the below
logs..
libguestfs-test-tool

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).
libguestfs: error: /usr/bin/supermin exited with error status 1, see debug
messages above

libguestfs: closing guestfs handle 0x10016848 (state 0)

Please help me regarding this.
Thanks
