Hot-add vCPU and memory to VMWare RHEL 6 guests
The structure of the
/sys/devices/system/cpu/ tree has changed, and it looks like I cannot edit the online or offline files. Added a CPU via VMWare, and trying to figure out how to enable it so the OS will use it.
For rhel6 32 bit guest vmware does not support Hot Add Memory or Hot Add vCPU. For 64 bit rhel 6/6.1 guest hot add is supported.
Check the vmware comparability guide for details on various rhel OS versions. Click on the below link.
