I've debated this in my mind since I've been learning more about qemu. 
Some of
the bmc properties are being passed in to the interface and passed on to
the bmc.
Plus some IPMI systems have multiple interfaces that point to the same
bmc.  It
might be best to have the user create a bmc device then tie an interface
device to it.

If I do this, what is the acceptable way to look up another object this
way?  I hunted
a bit and didn't come up with anything clean.

Thanks,
