I see. If this just copies the logic that qemu-iotests already uses, I think I would be okay with taking it as is for now. > > Or actually, should we work with a whitelist? > > I don't think that a hard-coded list will work well: Since we introduced > the Kconfig build system, it's now possible for example to also build an > qemu-system-aarch64 binary that does not contain any of the boards that > support virtio.

I'm just worried that the default config will end up running the tests on a machine type where it works, but if you use the wrong set of configure options, you end up with a setup where 'make check' fails because it uses a machine type that the iotests don't support.
