Long story short we need to expose these options so apps have a usable way to support rhel6 + virtio + q35. This series exposes the new devices as model= values. This required adding new model= attributes for several devices. See v1 posting for a summary of the XML changes introduced, mostly it's adding virtio-transitional and virtio-non-transitional to existing model= enums, and adding model= XML attributes for devices that don't have them (disk, fs, input)
Changes from v1: - <filesystem> models are now named virtio-9p, virtio-9p-transitional, virtio-9p-non-transitional. This is to avoid ambiguity as in the near future we will likely add virtio-fs <filesystem> support
- Cleanup and prep work is separated into separate patches and front loaded into the series.
- qemu caps additions are separated from the qemu_command.c patches, and squashed together upfront.
- virDomainDeviceSetData is added to make it easier to compose a virDomainDeviceDef on the fly. This is used for the transitional cli building but can be useful elsewhere too, but that's for another series.
- Lots of small improvements and fixes suggested by Andrea.
Forgot to mention, another relevant change is adding disable-modern=off alongside disable-legacy=on, from the v1 subthread with danpb and ehabkost Thanks, Cole
