Hello,
a few quick questions:
What exactly makes a "microhypervisor" different from an ordinary
microkernel? I see how the term hypervisor makes sense for something
like xen that cannot really be used sensibly by "stand-alone"
applications, but looking at your spec it looks just like a (quite nice)
microkernel.
How is capability revocation implemented? Are there any bounds on the
execution time? If not, how are arbitrarily long kernel paths scheduled?
(obviously an atomic interrupt-style kernel is not viable then ...)
Is there any support for asynchronous IPC?
Regards,
Tom
