Solution Verified - Updated -

Issue

  • 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.

Environment

  • Red Hat Enterprise Linux 6 all versions
  • 64 bit and 32 bit guest
  • VMware ESX 5.5 , 5.1 , 5.0 , 4.1 , 4,0(It includes the update release version)
