Encrypted vSphere vMotion States
For virtual machines that are not encrypted, you can set encrypted vSphere vMotion to one of the
following states. The default is Opportunistic.
Disabled Do not use encrypted vSphere vMotion.
Opportunistic Use encrypted vSphere vMotion if source and destination hosts support it.
Only ESXi versions 6.5 and later use encrypted vSphere vMotion.
Required Allow only encrypted vSphere vMotion. If the source or destination host
does not support encrypted vSphere vMotion, migration with vSphere
vMotion is not allowed.
When you encrypt a virtual machine, the virtual machine keeps a record of the current encrypted vSphere
vMotion setting. If you later disable encryption for the virtual machine, the encrypted vMotion setting
remains at Required until you change the setting explicitly. You can change the settings using Edit
Settings.
See the vCenter Server and Host Management documentation for information on enabling and disabling
encrypted vSphere vMotion for virtual machines that are not encrypted.
Encryption Best Practices, Caveats, and Interoperability
Any best practices and caveats that apply to the encryption of physical machines apply to virtual machine
encryption as well. The virtual machine encryption architecture results in some additional
recommendations. As you are planning your virtual machine encryption strategy, consider interoperability
limitations.
Virtual Machine Encryption Best Practices
Follow virtual machine encryption best practices to avoid problems later, for example, when you generate
a vm-support bundle.
General Best Practices
Follow these general best practices to avoid problems.
n
Do not encrypt any vCenter Server Appliance virtual machines.
n
If your ESXi host crashes, retrieve the support bundle as soon as possible. The host key must be
available for generating a support bundle that uses a password, or for decrypting a core dump. If the
host is rebooted, it is possible that the host key changes. If that happens, you can no longer generate
a support bundle with a password or decrypt core dumps in the support bundle with the host key.
n
Manage KMS cluster names carefully. If the KMS cluster name changes for a KMS that is already in
use, a VM that is encrypted with keys from that KMS enters a locked state during power on or
register. In that case, remove the KMS from the vCenter Server and add it with the cluster name that
you used initially.
