This is in preparation of the enablement of s390 guests with virtio devices.

The assignment of device addresses happens in different places, i.e. the qemu driver and process modules as well as in the unit tests in slightly different flavors. Currently, these are PPC spapr-vio and PCI devices, virtio-s390 (not PCI based) will follow.

By optionally passing to qemuDomainAssignAddresses the domain object and the capabilities it is now possible to call the function from most of the places (except for hotplug) where address assignment is done.

Hi Michal,

actually I was pondering about a doc update when preparing the patches. I only wasn't clear where to put it. The only place where possible arch/machine values are mentioned seems to be in formatcaps.html.in. Would you expect me to add a sample output of the capabilities XML for s390 with some comments in there, or did you have something else in mind?

Thanks.

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.

Okay. I've pushed the patch set. Michal
