The PowerNV machines uses ISA as the default serial type.
ISA? Are you sure?
ISA is very legacy x86 bus.
Yes, these machines uses ISA buses.
Okay, I have very hard time believing it, but I'm not an expert on Power machines.
I believe that since it's also uses an UART the bus itself isn't that much of a deal.
Well, it does matter, because with isa-serial you can configure an ISA address for it: <address type='isa' iobase='0x3f8' irq='0x4'/> I also see that 'isa-serial' is mentioned by the ppc64 capability dump, but in this case I'm not sure whether it's because it really supports an ISA device or it's just that qemu exposes all platform-specific serial ports as 'isa-serial'.
