A. Getting started:

B. Nice to know:

Get-Vm |Get-VirtualNetworkAdapter |Where {$_.IPv4Addresses -like "192.168.123*"} | Select Name, IPv4Addresses

Get-Vm |Get-VirtualNetworkAdapter |Where {$_.MACAddress -like "00:15:5D:*"} | Select Name, MACAddress

Get-VMHost | %{ get-scvmhostnetworkadapter -VMHost $_ | where-object {$_.PhysicalAddress -like "00:25:B5*" }} | Select VMHost, PhysicalAddress

				$VMHost = Get-SCVMHost -ComputerName "HyperVHostName"
				Register-SCVirtualMachine -VMHost $VMHost -Path "C:\ClusterStorage\MyVM"

From the following:


We will get this in PowerShell:

Set-SCVirtualMachine -VM "VMName" -FirstBootDevice "SCSI,0,1"

To set the first boot device to be a NIC using PXE boot:

Set-SCVirtualMachine -VM (Get-VM "VMName") -FirstBootDevice "NIC,0"

You can also start Cluster Manager -> Nodes -> choose VM and set boot device there. It is not possible to do this on Generation 2 virtual guests in the GUI via VMM. It is however possible on Generation 1 virtual guests(it has to be powered off, here it is powered on):



As a comparrison, a generation 2 virtual machine guest looks like this in the same menu area:



Please see: http://technet.microsoft.com/library/dn440675.aspx
"Because of underlying differences between generation 1 and generation 2 virtual machines, the startup order (boot order) for different devices (such as a hard disk or CD) is not handled the same way in the two generations. To customize the startup order for a generation 2 virtual machine in System Center 2012 R2, you must use a Windows PowerShell command that specifies the first boot device, rather than an ordered list of boot devices."
