Activate Host Encryption Mode Explicitly

Host encryption mode must be set if you want to perform encryption tasks, such as creating an encrypted virtual machine, on an ESXi host. In most cases, host encryption mode is activated automatically when you perform an encryption task.

Sometimes, turning on encryption mode explicitly is necessary. See Prerequisites and Required Privileges for Virtual Machine Encryption Tasks.
