The guest memory layout created by kvmtool is fixed: regular MMIO is

Real
hardware can have a different memory layout, and being able to create
a
specific memory layout can be very useful for testing the guest
kernel.
This series allows the user the specify the memory layout for the
virtual machine by expanding the -m/--mem option to take an <addr>
parameter, and by adding architecture specific options to define the
I/O
ports, regular MMIO and PCI MMIO memory regions.
The user defined memory regions are implemented in patch #16; I
consider
the patch to be an RFC because I'm not really sure that my approach
is the
correct one; for example, I decided to make the options arch
dependent
because that seemed like the path of least resistance, but they could
have
just as easily implemented as arch independent and each architecture
advertised having support for them via a define (like with RAM base
address).
Do you plan to repost this with Andre's comments addressed?
The series will conflict with my other series which add support for
assignable
BARs and PCIE. I am definitely still interested in reposting this
because I think
it's very useful, and I'll do it after the other patches get merged.
I'd be happy to review the rebased version. I definitely need it to
support some of my most funky HW...
