The encryption feature has certain limitations.
- You must power off a virtual machine before you add or remove encryption or change the encryption password.
- The encryption feature supports virtual machines that have virtual hardware version 5.x or later only.
- You cannot create a linked clone from an encrypted virtual machine.
- If more than one unencrypted virtual machine shares the same virtual disk and you encrypt one of the virtual machines, the virtual disk becomes unusable for the unencrypted virtual machine.
- You cannot encrypt a remote virtual machine.
- You cannot upload an encrypted virtual machine to a remote server.
- You cannot change the encryption state (encrypted/ decrypted) when snapshots exist.
