I'm not a fan of this approach. The capabilities data is reflecting

not convinced this is the best possible definition ... we would
have seen more issues with it if the machine type would really have
had a meaning on other architectures, e.g., if -M isapc would not
allow to instantiate PCI devices. But since...
The decision about whether to use S390 or CCW based on the machine
type value, should be made by the internal method at the point when
it actually assigns addresses, not when we create the capabilities
initially.

...I can certainly use the vm definition to figure out which address
type to choose that should work. Let me run a few tests to prove that and I will come back with a V3 for 3-5/5 in the next couple of days.
