Why devise a VM when the e5500 core has this capability built in? See:

http://www.nxp.com/files/32bit/doc/white_paper/EMBEDDED_HYPERVISOR.pdf (refers to the e500mc core but is valid for e5500 and e6500 as well)
http://www.linux-kvm.org/page/E500_virtual_CPU_specification (also for e5500 and e6500)

Using the e5500's embedded hypervisor (Topaz), running Linux in parallel would be no problem. MacOSX wouldn't be possible, though, as it's not compatible with the e5500 core on supervisor level (and lacks drivers for the QorIQ P5's on-chip controllers).

Why do you think this would be easier than the other way round?
