Is Hot remove of CPU and Memory possible without powering off VM?. If yes what all operating systems supports this.
In most of the blogs i have read that hot add is possible in new versions of OS. But not hot remove.

for Linux in additional take a look Hot add cpu to supported Linux guestOSes using vSphere ESX(i) 4.0
and Hot-add vCPU is not automatically activated in some SLES 11 guests
I know hot add is supported in few OS. I need information on Hot remove of CPU and memory.
Thanks in advance
Take a look at Which guest OS supports hot remove of CPU?
Currently VMware nor any of the existing Guest Operating systems available in market support Hot remove of CPU/Memory .
Hope this helps ..
IBM PowerVM lets you do that.
