Description

The Set-VM cmdlet configures a virtual machine.

Examples

Example 1

PS C:\> Set-VM -Name TestVM -AutomaticStopAction Shutdown

Configures virtual machine TestVM to shut down when the Hyper-V host shuts down.

Example 2

PS C:\> Stop-VM -Name TestVM -Passthru | Set-VM -ProcessorCount 2 -DynamicMemory -MemoryMaximumBytes 2GB -Passthru | Start-VM

Stops virtual machine TestVM, sets it to use dynamic memory, sets its maximum amount of memory to 2GB, sets it to use 2 virtual processors, and starts it.
