Yes. that's the main issue. OpenPOWER firmware should be available
for people to use on P10 but it won't have any support AFAIK. We just 
published skiboot as part of it.

The hypervisor on the host (pHyp) replaces the software stack : 

    skiboot + Linux(PowerNV) + KVM + QEMU + SLOF

and it comes with its own system management driven from the FSP/BMC.
