6.5.1

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 seing. If you later disable encryption for the virtual machine, the encrypted vMotion seing
remains at Required until you change the seing explicitly. You can change the seings using Edit .
See the vCenter Server and Host Management documentation for information on enabling and disabling
encrypted vSphere vMotion for virtual machines that are not encrypted.
Enable or Disable Encrypted vMotion
You can enable encrypted vMotion during virtual machine creation. You can later change the encrypted
vMotion state from the virtual machine seings. You can change the encrypted vMotion state only for
virtual machines that are not encrypted.
For more information about virtual machine encryption, see “Encrypted vSphere vMotion,” on page 119.
Prerequisites
Encrypted vMotion is supported only in vSphere 6.5 and later.
Procedure
1 Right-click the virtual machine and select Edit .
2 Select VM Options.
3 Click Encryption, and select an option from the Encrypted VMotion drop-down menu.
Disabled
Do not use encrypted vMotion.
Opportunistic
Use encrypted vMotion if source and destination hosts support it. Only
ESXi hosts of version 6.5 and later use encrypted vMotion.
Required
Allow only encrypted vMotion. If the source or destination host does not
support encrypted vMotion, migration with vMotion fails.
Virtual Machine Conditions and Limitations for vMotion
To migrate virtual machines with vMotion, the virtual machine must meet certain network, disk, CPU, USB,
and other device requirements.
The following virtual machine conditions and limitations apply when you use vMotion:
n
The source and destination management network IP address families must match. You cannot migrate a
virtual machine from a host that is registered to vCenter Server with an IPv4 address to a host that is
registered with an IPv6 address.
n
You cannot use migration with vMotion to migrate virtual machines that use raw disks for clustering.
n
If virtual CPU performance counters are enabled, you can migrate virtual machines only to hosts that
have compatible CPU performance counters.
