[Skiboot] Skiboot on qemu questions

Hello all.

Once again dusting off my coreboot work, making fairly good progress I
think (at least when running against a virtualized system via LeGoater's
qemu powernv target) and was a bit curious about a few things.

In the context of running skiboot in qemu, is it 'considered' emulated?
As in, will it hit hypervisor exceptions? Currently I'm catching
excpetions 0xe00 and 0xe40 when jumping from romstage to ramstage, which
are both hypervisor exceptions. Wondering if I should be worried about
this. What about skiboot on real hardware?

Some info and teaserish: https://i.imgur.com/07d2Q0y.png
