Hrm, works for me, I've been testing various LE kernels including a full ubuntu distro in there, we need to debug that further. Does that same kernel actually work on real HW ? > If I try LE disk image (ubuntu 14), it just crashes: > > p/qemu-powernv/ppc64-softmmu/qemu-system-ppc64 -m 2048 -machine > powernv \ > -nographic -vga none img/u14_32GB_cuda7.qcow2 -bios skiboot.lid \ > -smp 1,threads=1 > qemu: hardware error: qemu: could not load kernel'(null)' Right, we don't load kernels from disk, you need to pass a -kernel that typically is the openpower bootloader (Linux + petitboot). My plan is to make the pnv platform automatically extract these things from a ROM image of an openpower eval board (aka palmetto) which you can build from github. It's a bit too big to include as a binary in qemu however (about 16M). > Right. With the note that it goes with -bios :) Not necessarily, it will be in the right place and loaded without an explicit -bios. Cheers, Ben.
