[<CommonParameters>]Description
The Set-VMFirmware cmdlet sets the firmware configuration of a Generation 2 virtual machine.
Examples
Example 1
PS C:\> Set-VMFirmware "Test VM" -EnableSecureBoot OnThis example enables secure boot functionality on the virtual machine "Test VM".
Example 2
PS C:\> Set-VMFirmware "Test VM" -FirstBootDevice $vmNetworkAdapterThis example sets the virtual machine "Test VM" to boot off of the VM network adapter object stored in $vmNetworkAdapter. This object was acquired using get-VMNetworkAdapter.
Example 3
PS C:\> Set-VMFirmware "Test VM" -BootOrder $vmNetworkAdapter, $vmHardDiskDriveSets the boot order for the virtual machine "Test VM". $vmNetworkAdapter contains a VM Network Adapter object (acquired using get-VMNetworkAdapter) and $vmHardDiskDrive contains a VM hard disk object (acquired using get-VMHardDiskDrive). Any existing boot entries not specified by this command will be removed from the virtual machine.
Parameters
-BootOrder
Specifies an array of devices. The boot order determines the order of the devices from which to boot. The acceptable values for this parameter are:
-- VMBootSource
-- VMNetworkAdapter
-- HardDiskDrive
-- DVDDrive
The VMBootSource value describes a boot entry in firmware nonvolatile Random Access Memory (NVRAM).
| Type: | VMComponentObject[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-CimSession
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession or Get-CimSession cmdlet. The default is the current session on the local computer.
| Type: | CimSession[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ComputerName
Specifies the names of the Hyper-V hosts whose firmware configuration you want to modify.
| Type: | String[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Confirm
Prompts you for confirmation before running the cmdlet.
| Type: | SwitchParameter |
| Aliases: | cf |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-ConsoleMode
Specifies the console mode type for the virtual machine. This parameter allows a virtual machine to run without graphical user interface.
| Type: | ConsoleModeType |
| Accepted values: | Default, COM1, COM2, None |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Credential
Specifies one or more user accounts that have permission to perform this action. The default is the current user.
| Type: | PSCredential[] |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-EnableSecureBoot
Specifies whether to enable secure boot. The acceptable values for this parameter are:
-- On
-- Off
Secure boot uses a public key infrastructure that protects the integrity of the operating system.
| Type: | OnOffState |
| Accepted values: | On, Off |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-FirstBootDevice
Specifies the device from which to attempt to boot from first. The acceptable values for this parameter are:
-- VMBootSource
-- VMNetworkAdapter
-- HardDiskDrive
-- DVDDrive
The VMBootSource value describes a boot entry in firmware NVRAM.
| Type: | VMComponentObject |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Passthru
Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-PauseAfterBootFailure
Specifies the behavior of the virtual machine after a start failure. For a value of On, if the virtual machine fails to start correctly from a device, the virtual machine is paused.
| Type: | OnOffState |
| Accepted values: | On, Off |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-PreferredNetworkBootProtocol
Specifies the IP protocol version to use during a network boot.
| Type: | IPProtocolPreference |
| Accepted values: | IPv4, IPv6 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-SecureBootTemplate
Specifies the name of the secure boot template. If secure boot is enabled, you must have a valid secure boot template for the guest operating system to start.
| Type: | String |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-SecureBootTemplateId
Specifies the ID of the secure boot template.
| Type: | Guid |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-VM
Specifies the virtual machine objects for which want to modify the firmware configuration. To obtain a virtual machine object, use the Get-VM cmdlet.
| Type: | VirtualMachine[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
