[<CommonParameters>]Description
The Restart-VM cmdlet restarts a virtual machine. Running this cmdlet results in a "hard" restart, like powering the computer down, then back up again. This can result in data loss in the virtual machine.
Examples
Example 1
PS C:\> Restart-VM Win7
Confirm
Are you sure you want to restart virtual machine "win7"?
[Y] Yes [A] Yes to All [N] No [L] No to All [S] Suspend [?] Help (default is "Y"): yPerforms a hard restart of virtual machine Win7. This is equivalent to turning off the power to the virtual machine and then restarting it.
Parameters
-AsJob
Runs the cmdlet as a background job.
| Type: | SwitchParameter |
| 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 one or more Hyper-V hosts on which the virtual machine is to be restarted. 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.
| 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 |
-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 |
-Delay
| Type: | UInt16 |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-For
| Type: | WaitVMTypes |
| Accepted values: | Heartbeat, IPAddress |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Force
Specifies that no prompt for confirmation is to appear before the virtual machine is restarted.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Name
Specifies the name of the virtual machine to be restarted.
| Type: | String[] |
| Aliases: | VMName |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Passthru
Specifies that an object is to be passed through to the pipeline representing the virtual machine to be restarted.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-Timeout
Specifies the duration of the wait, in seconds. When the timeout elapses, Restart-VM returns to the command prompt, even if the virtual machine isn't restarted.
This parameter is only valid with the -Wait parameter. The -Timeout parameter overrides the -Wait parameter's indefinite waiting period.
| Type: | Int32 |
| Aliases: | TimeoutSec |
| Position: | Named |
| Default value: | None |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-VM
Specifies the virtual machine to be restarted.
| Type: | VirtualMachine[] |
| Position: | 0 |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | True |
| Accept wildcard characters: | False |
-Wait
Restart-VM suppresses the PowerShell prompt and blocks the pipeline until the virtual machine has restarted. You can use this parameter in a script to restart the virtual machine and then continue to process when the restart is finished.
The -Wait parameter waits indefinitely for the virtual machine to restart. You can use the -Timeout parameter to adjust the timing and the -For and -Delay parameters to wait for particular services to become available on the restarted virtual machine.
| Type: | SwitchParameter |
| Position: | Named |
| Default value: | None |
| Required: | True |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
-WhatIf
Shows what would happen if the cmdlet runs. The cmdlet is not run.
| Type: | SwitchParameter |
| Aliases: | wi |
| Position: | Named |
| Default value: | False |
| Required: | False |
| Accept pipeline input: | False |
| Accept wildcard characters: | False |
Outputs
None by default, Microsoft.HyperV.Powershell.VirtualMachine if PassThru is specified.
