Can i scale up/scale down computing resource(i.e. cpu, ram, disk) on running vm instances without shutting it down?
Can i add more computing power i.e. cpu, ram, disk to live/running vm instances without shutting it down?
can i set a threshold in such a way that if cpu usage exceeds 80% then automatically add additional computing power such as add couple of more CPU cores to running VM instance, can do this ? how do i configure this in nova? pls suggest.
Thanks in advance.
