Which feature do you think can be improved?

Currently VFIO devices are added but not removed. There is highlevel integration that uses a feature to remove a device at runtime but kata uses to do clean up before destroy the VM.

How can it be improved?

Implement hotplugRemoveDevice and remove vfio devices from hypervisor.

Additional Information
