How to enable kerberos authentication type for live migration in hyper-v by using Powershell cmdlet ?

How to enable kerberos authentication type for live migration in hyper-v by using Powershell cmdlet ?

• set-vmhost -authenticatiuontype kerberos
• install-vmhost -virtualmachinemigrationauthenticatiuontype kerberos
• set-vmhost -virtualmachinemigrationauthenticatiuon type kerberos
• install-vmhost -authenticatiuontype kerberos

EXPLANATION

Use Windows PowerShell to set up the source and destination computers for live migration

Three cmdlets are available for configuring live migration on non-clustered hosts: Enable-VMMigration, Set-VMMigrationNetwork, and Set-VMHost. This example uses all three and does the following:

• Configures live migration on the local host
• Allows incoming migration traffic only on a specific network
• Chooses Kerberos as the authentication protocol

Each line represents a separate command.

PS C:\> Enable-VMMigration  

PS C:\> Set-VMMigrationNetwork 192.168.10.1  

PS C:\> Set-VMHost -VirtualMachineMigrationAuthenticationType Kerberos
