Detailed Description

The Set-VMProcessor cmdlet configures one or more processors of a virtual machine.

Parameters

-ComputerName<String[]>

Specifies one or more Hyper-V hosts on which processors are to be configured. NetBIOS names, IP addresses, and fully-qualified domain names are allowable. The default is the local computer — use “localhost” or a dot (“.”) to specify the local computer explicitly.

<CommonParameters>

This cmdlet supports the common parameters: -Verbose, -Debug, -ErrorAction, -ErrorVariable, -OutBuffer, and -OutVariable. For more information, see    about_CommonParameters.

Inputs

The input type is the type of the objects that you can pipe to the cmdlet.

Outputs

The output type is the type of the objects that the cmdlet emits.

  • None by default; Microsoft.Virtualization.Powershell.VMNetworkAdapterVlanSetting if –PassThru is specified.


Examples

Example 1

Configures virtual machine TestVM with two virtual processors, a reserve of 10%, a limit of 75%, and a relative weight of 200.


PS C:\> Set-VMProcessor TestVM -Count 2 -Reserve 10 -Maximum 75 -RelativeWeight 200

Example 2

Configures virtual machine TestVM, enabling processor compatibility for live migration.


PS C:\> Set-VMProcessor TestVM -CompatibilityForMigrationEnabled $true

Example 3

Configures virtual machine TestVM, enabling compatibility for running older operating systems.


PS C:\> Set-VMProcessor TestVM –CompatibilityForOlderOperatingSystemsEnabled $true
