We discussed how to create machines from QMP without needing to recompile QEMU. Three different problems: - startup QMP (*) not discussed today - one binary or two not discussed today - being able to create machines dynamically. everybody agrees that we want this. Problem is how. - current greensocs approach - interested for all architectures, they need a couple of them what greensocs have: - python program that is able to read a blob that have a device tree from the blob - basically the machine type is empty and is configured from there - 100 machines around 400 devices models - Need to do the configuration before the machine construction happens - different hotplug/coldplug - How to describe devices that have multiple connections As the discussion is quite complicated, here is the recording of it. Later, Juan. https://redhat.bluejeans.com/m/TFyaUsLqt3T/?share=True *: We will talk about this on the next call
