CPU hot-plug and RAM hot-add in virtual machines

The question is simple but I cannot find answer - Does FreeBSD support 
hot-plug vCPU and hot-add RAM?
Current virtualization platforms support adding CPU cores or additional 
RAM without the need to reboot the guest OS. Some of our clients need to 
add additional vCPUs or RAM so often that hot-plug and hot-add will be 
really useful. If this is not supported on FreeBSD for now, is there any 
Work In Progress? Or is there a plan to support it?

Kind regards
