I have made a powershell script function to update information about what VLAN and IP the VM´s have. This for the IT Admin to easily see in the VMM 2012 Console. Of course the function can be customized to populate any other information available for the VM´s, maybe you want to display create date or something else that is not in the standard properties and you do not want to use the pre-made custom# .

I am using the Get-IPAddress from Ben Wilkinson, This requires that the VMM server can resolve the IP of the VM´s from a DNS.

If I do not have an DNS or the VLAN info is not stored, i can via the parameters update the properties by -IP or -VLANid.

As you can see on this screen dump, by default i only have custom#, to add my own i have to click on “Manage Custom Properties”

Here i press “Create” and add a name and optionally a description

Then when i have created the custom properties i want i add them,

Then it looks like this,

Now the powershell function comes into play when i am going to populate these fields with information.

function Set-CustomValue{
# Function to add custom data on VMs

    param (
   [Parameter(Position=0,Mandatory=$true,HelpMessage="A virtual machine pleaze",
    ValueFromPipeline=$True)]
    $VM,
	$VLANid = "",
	$IP = ""
    )
    . .\Get-IPAddress.ps1
    
    $VM = Get-SCVirtualMachine $VM
	
  	$CustomIP = Get-SCCustomProperty -Name "IP"
    $CustomVLAN = Get-SCCustomProperty -Name "VLAN"
    
	if ($IP -eq ""){
		$IP = Get-IPAddress -HostName $VM.Name
    }
	
	if ($VLANid -eq ""){
	    $VMnics = $VM | Get-SCVirtualNetworkAdapter
	    if($VMnics.Count -ne $null){
	        foreach ($VMnic in $VMnics){
	            $VLANid = $VLANid + $VMnic.VlanID + " "
	        }
	        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VLANid
	    }else{
	        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VMnics.VlanID
	    }
    }else {
		Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomVLAN -Value $VLANid
	}
    if($IP -ne ""){
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $CustomIP -Value $IP       
    }
}

a screendump of my powershell console, as you can see I am using the (Get-SCVMHostCluster).Nodes to get all virtual machines on these, also i am using a foreach (%) to run the population on each VM.

And this is how it looks in the VMM console,

I have made a simple powershell function that can move VM´s from one cluster to another and also set the network configuration, this because the old cluster had one way of setup regarding the virtual machine network and the new another more flexible with promiscuous mode set on the HP nic team so i do not need to create one virtual switch for every vlan. The function also checks if the actual VM has snapshots before moving it. (the SCVMM calls it checkpoints, which is stupid to call it one thing in hyper-v and another in SCVMM!)

the powershell function looks like this:

function Migrate-VM {

param (
   [Parameter(Position=0,Mandatory=$true,HelpMessage="A virtual machine pleaze",
    ValueFromPipeline=$True)]
    $VM,
    [Parameter(Mandatory=$true)]$VMHost,
    $VMnic,
    $VMnetwork = "VMs",
    $Datastore = "C:\ClusterStorage\Volume1",
    [switch]$StartVM
    )
    
    if( Get-SCVirtualMachine $VM | Get-SCVMCheckpoint) {
		$VM = Get-SCVirtualMachine $VM
		Write-Host " Please remove snapshots and do a shutdown of the VM:" + $VM.Name
    }else{
	    $JobGroupID = [guid]::NewGuid()
	    
	    $VMHost = Get-SCVMHost $VMHost
	    $VMnic = Get-SCVirtualMachine $VM | Get-SCVirtualNetworkAdapter
	    
	    $LogicalNetwork = (Get-SCLogicalNetworkDefinition -VLanID $VMnic.VlanID).LogicalNetwork

	    Set-SCVirtualNetworkAdapter -VirtualNetworkAdapter $VMnic -RunAsynchronously -VirtualNetwork $VMnetwork -LogicalNetwork $LogicalNetwork -VLanEnabled $true -VLanID $VMnic.VlanID -JobGroup $JobGroupID -EnableVMNetworkOptimization $false -EnableMACAddressSpoofing $false
	    if($StartVM){
	        Move-SCVirtualMachine -VM $VM -VMHost $VMHost -HighlyAvailable $true -Path $Datastore -StartVMOnTarget -RunAsynchronously -UseLAN -JobGroup $JobGroupID
	    }else
	    {
	        Move-SCVirtualMachine -VM $VM -VMHost $VMHost -HighlyAvailable $true -Path $Datastore -RunAsynchronously -UseLAN -JobGroup $JobGroupID
	    }
    }   
    
}

And this screendump shows some different ways of running it,

Had a plan to do a blog post last week but was so busy studying for the VCP 5 test. I wrote the test on friday and i passed 🙂

I have created a little powershell function, this to get the inventory information about the virtual machines running in hosts or clusters that are connected to a System Center Virtual Machine Manager. This function collects number of configured vCPU´s, Memory, information about the connected virtual harddisks. This kind of information could be handy as in the case with one customer that has not yet implemented a host based backup solution and still use agents in their VM´s, so if they need to recover machines it is good to know what size and configuration it had if it is lost by some reason. This report can also be handy for some info on how much your datastores are filled. As you can se i both report the maximum size and the current (as dynamic disks are not allocating the whole size at creation time)

The function both export a csv and a HTML report

After importing it to excel it can look something like this:

And the html output is very simple but can be put on a internal web for IT production

I have used the Get-SCVirtualDisk to get the Bus Type and LUN id as this information is not available in Get-SCVirtualHarddisk, this information can be good if i lost the virtual machine configuration and want to connect the virtual harddisks to the right controller.

the function looks like this: (if you copy this you have to move the first # up to the <, the blog syntax highlighter does something and move it down :-( )

function Get-VMdata{
<#

}

and i can run it in some different ways, as you see in this screenshot, if i do not give any parameters it will use VMHostGroup “All Hosts” as default
