    Why would an x64-native MorphOS need to run on "a software based hypersvisor on a X64 system"?

    ...using QEMU's mac99 virtualization with KVM-PR, that is.

    Why not run this potential little-endian PPC64 version of MorphOS on bare metal (PowerNV) instead of boxed?

    I'm not sure the hypervisor can help with emulating x64 on POWER.

    OS4 already runs fine on QEMU's Sam460 emulation. Btw, QEMU already has P50X0/e5500 emulation but that isn't enough to run OS4 as there's more to a board/system than just the CPU.

    > or better yet e6500 core emulation

    OS4 doesn't run on e6500.

    3 generations.

    Code that has been cleaned from big-endian assumptions and adapted to modernized MorphOS API should just need a recompile for a potential x64 MorphOS.

    QEMU supports clipboard sharing between guest and host (and thus also between guests). There needs to run a special service in the guest OS for this to work, though, which doesn't exist yet for AmigaOS or MorphOS.
