Actually, now I am going through docs I don't see a proper place
neither. Moreover, in formatdomain.html.in we state: "The Capabilities
XML provides details on allowed values for these" [these = @machine and
@type] So as long as we report them in capabilities XML I guess we don't
really need an doc extension.
However, I think this [1] should be virtio-s390 instead of s390-virtio
since we use the former among the code.
What do you think?
Michal
the naming is awkward and I stumble over it from time to time too.
Unfortunately this is the terminology qemu uses.
In a nutshell:
s390-virtio = machine type, meaning s390 machine with virtio bus
virtio-s390 = bus type, meaning s390-specific virtio bus
The current virtio bus on s390 is a fully virtual bus not related to a
real hardware bus like the PCI bus on the other architectures. So, while
the names looks strange, they are technically correct.
