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