This probably shouldn't be 0 in the example, nor in your kvm tool
output. For example purposes any value will do.

Hmm, so kvmtool actually provides a PC ioport at 0x0, which is handy since
there's an 8250 down there. That means we have:

0x0    - 0x6200  : Weird PC stuff
0x6200 - 0x10000 : PCI IO space

Should I just change everything to be offset by 0x6200?

Do you have a list of the stuff in there?

If that is actually port I/O, leaving it in there may be best,
but I agree the example should be changed.
