Comprehensive and Detailed Explanation From Exact Extract:
When scaling CPU and RAM for a virtual machine in a VMware Cloud Foundation environment, the administrator must consider these limitations:
To add Memory to a powered on virtual machine, Memory Hot Add must be enabled (A): Without Memory Hot Add, adding memory requires the VM to be powered off.
To add vCPUs to a powered on virtual machine CPU Hot Add must be enabled (C): CPU Hot Add allows additional virtual CPUs to be added while the VM is powered on; otherwise, the VM must be powered off.
To enable the CPU Hot Add or Memory Hot Add feature, the virtual machine must be powered off (F): These features can only be activated or changed when the VM is not running.
Removing memory while powered on is not supported, and enabling these hot add features does not require the VM to be at a specific hardware compatibility level unless specified by certain new functionalities, but the core requirement is the VM must be powered off to enable the features. Adding vCPUs to a powered off VM does not require CPU Hot Add.
