I have changed the number of vCPU from 1 to 4 in a Vsphere console for a virtual machine running RHEL 4.8 but the change is not dedected in OS. The server is still running with 1 CPU. Below are the steps I did to change the number of vCPUs. 1. Powered off the VM -> Edit Settings -> Changed the vCPU number to 4 -> Apply.
2. Powered on the VM
Once the OS came up I checked /proc/cpuinfo still it showed CPU - 1. I am not sure if i am missing some thing... Appreciate any help to resole this issue.
