We have a virtual server that is Centos 6 64-bit with one core. It has Zenoss on it. We are using VMware to host the virtuals. We would like to take it to two cores. I have done research and seen that it would cause the system to run slow. I was wondering since this is a version of Linux would this cause the system problems adding a additional core. Is there anything I have to do in the CentOS to get the new core installed or just shut it down and add it?
