ok, so what is the problem here?

Handling the hotplug in userspace through udev may be suboptimal and
kernel handling might be faster but that's orthogonal to the problem at

The state of the art is to determine what to do with hotplugged memory
in userspace based on platform and virtualization type.

Changing the default to depend on the driver that added the memory
rather than platform type should solve the issue of VMs growing
different types of memory device emulation.

Am I missing something?
