$VMtoStart = Get-VM | where notes -contains 'Boot order 1' The following PowerShell script starts virtual machines in a specific order and runs extra availability checks for some services (TCP ports) in the VM using the PowerShell cmdlet Test-NetConnection: Set-vm lon-rds01,lon-app01 -Notes "Boot order 3" Set-vm lon-exch1, lon-db01 -Notes "Boot order 2" Set-vm lon-dc01,lon-dc02 -Notes "Boot order 1" For example, I have set the following tags for the VMs: To make it more convenient, you can join several VMs into a group using tags. In the script, you can set a delay before starting the next VM and perform additional checks for the availability of an application or service in the VM (to make sure that the app or service has been started). Get-VM –VMname lon-rds01,lon-app01 | Set-VM –AutomaticStartDelay 180Īnother way is to start VMs in turn using a PowerShell startup script. Get-VM –VMname lon-exch1,lon-db01 | Set-VM –AutomaticStartDelay 90 Get-VM –VMname lon-dc01| Set-VM –AutomaticStartDelay 0 In the simplest cases, you can configure the order of VM startup by setting different startup delays for them: Hyper-V doesn’t have any built-in tools to manage startup order of the virtual machines, except for the start delay option ( AutomaticStartDelay). For example, you need the Exchange VM to boot only after the domain controller is available, and an app server to start after a database server. When starting a standalone Hyper-V host, an administrator must manage the startup order of virtual machines on it. Boot (Startup) Order of Hyper-V Virtual Machines Using the – AutomaticStopAction option, you can set the VM shutdown settings ( Save, TurnOff, ShutDown). Get-VM –VMname * | Where-object –FilterScript | Set-VM –AutomaticStartDelay 90

To set up startup delay for all VMs except for one (for example, a domain controller with FSMO roles):

You can use PowerShell to configure virtual machine settings on a free Windows Hyper-V Server host that has no GUI. Its possible values are Nothing, StartIfRunning, Start. You can change the automatic startup settings of a VM using the AutomaticStartAction option. Get-VM –VMname * | Select-Object VMname,AutomaticStartAction,AutomaticStartDelay,AutomaticStopAction You can view and change the automatic startup and shutdown settings of your Hyper-V virtual machines using PowerShell.ĭisplay the current startup and shutdown settings of all VMs: All apps running in the VM are stopped and the risk of getting inconsistent data is very low. Shutdown the guest operating system – a guest OS is shutdown using Hyper-V integration service (graceful shutdown).In this mode, there is some risk of getting inconsistent data in the apps running in the VM.

The VM state is not saved, a guest OS will be started with a full boot cycle.

Turn off the virtual machine – when a Hyper-V host is shutdown, a virtual machine will also be stopped (in the same way as a physical computer is shutdown).

Note that you must have additional free space on your disk to keep your VM memory (*.BIN files). At the next startup, the virtual machine will resume from this point.

Save the virtual machine state – a full state of a virtual machine is saved (including its memory).

The setting implies the correct restart of a Hyper-V host when virtual machines have time to shutdown gracefully, unlike emergency situations (unexpected power outage, BSOD). Using the delay, you can manage the boot order of your virtual machines (for example, to boot a domain controller before starting a VM with SQL Server), and reduce the load on the disk storage due to starting multiple VMs in turn. Here you can specify the startup delay time for the virtual machine (in seconds). One more parameter is available for the last option – Startup Delay.

Always start this virtual machine automatically – always start this virtual machine when the Hyper-V host boots.

Automatically start if it was running when the service stopped – a VM will automatically start only if it has been running before the host shutdown/restart.

Nothing – when a host is started, a virtual machine doesn’t start automatically (regardless of its state before the host restart).

Three options to manage the automatic startup of a virtual machine are available: Run the Hyper-V console, open the properties of any VM, and go to Settings -> Automatic Start Action. Automatic startup settings are configured for each VM individually. It means that if a VM was running before a restart, Hyper-V will start it automatically.
