Hello,
If you played with some preview build of Windows 10 and/or Windows Server 2016, you may want to upgrade your VM configuration version. Indeed, Ben published an interesting version/feature table :
Feature Name | Minimum VM version | |
---|---|---|
Hot Add/Remove Memory | 6.0 | |
Hot Add/Remove Network Adapters | 5.0 | |
Secure Boot for Linux VMs | 6.0 | |
PowerShell Direct | 6.2 | |
Production Checkpoints | 6.0 |
You can check each VM configuration version with PowerShell :
Or with the GUI :
To upgrade, you can use PowerShell : Update-VMVersion
Or the GUI :
Note : This is irreversible, you won’t be able to move those VM back to an older Hyper-V server.
