Description Stephen Finucane 2021-04-30 16:28:31 UTC 
Description of problem:

We are hoping to transition from the legacy, deprecated pc-i440fx (pc) machine type to the more modern pc-q35 (q35) machine type. The q35 machine type does not support a number of buses such as IDE along with devices like emulated floppy drives and device buses such as cirrus. In addition, RHEL 9 is removing a number of other devices models such as the QXL video device model. This RFE tracks the deprecation of these buses and devices along with the provision of tooling to transition them to their more modern equivalents.

Comment 2 Lee Yarwood 2021-06-17 15:46:59 UTC 
Discussed some more downstream and we need this to cover the initial recording of all and later update of the now stashed image properties specifically hw_disk_bus, hw_cdrom_bus, hw_rescue_bus, hw_video model and hw_vif_model.
