ThanksPlease help me regarding this.But still when i run libguestfs-test-tool on powerpc ubuntu,I get the below logs..Hi RichKindly 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.

If this is a Xen guest, and you only have Xen domU kernels

supermin use, you shouldn't boot the Xen guest with it).
