foreach ($VM in $VMs)
{
$VMName = $VM.Name
$Cloud = $VM.Cloud
if ($VM.PassThroughDisks)
{
$PassThroughDisk = "True"
Write-Host $VMName
Write-Host $Cloud
$Value = $VMName + ";" + $Cloud
Add-Content -Value $Value -Path C:\yusufozt\PassThroughDisks.txt
$Pt++
}
}
Write-Host "Total VM: $Pt" |
$Pt = 0;
$VMs = Get-VM
foreach ($VM in $VMs)
{
$VMName = $VM.Name
$Cloud = $VM.Cloud
if ($VM.PassThroughDisks)
{
$PassThroughDisk = "True"
Write-Host $VMName
Write-Host $Cloud
$Value = $VMName + ";" + $Cloud
Add-Content -Value $Value -Path C:\yusufozt\PassThroughDisks.txt
$Pt++
}
}
Write-Host "Total VM: $Pt"
You can export into Microsoft Excel for a table view.

Merhaba,
Cumartesi günü Microsoft Türkiye’de yapmış olduğum PowerShell ile Hyper-V Yönetimi sunumunda kullanmış olduğum Powerpoint ve Demo dosyalarına aşağıdaki bağlantı üzerinden ulaşabilirsiniz.
Sunum dosyaları içerisinde düzenlediğimiz toplam 3 tane dosya var.
http\template\main.html: Tabloları yarattığımız html dosyası
http\js\custom\jquery.vm.reports.js: XML’i okuyup, yorumlayan jscript
Get-MyVMs.ps1: Hyper-V’den değerleri çekip XML haline getirdiğimiz dosya
Herkese kolay gelsin :)

foreach ($Cloud in $Clouds)
{
$VMs = Get-SCCloud $Cloud | Get-VM
$VMCount = $VMs.Count
$TotalMemory = [math]::round((($VMs | Measure-Object -Sum MemoryAssignedMB).Sum / 1KB), 0)
$AvgMemory = [math]::round(($TotalMemory / $VMCount), 0)
Write-Host "Cloud: $Cloud"
Write-Host "VM Count: $VMCount"
Write-Host "Total Memory: $TotalMemory GB"
Write-Host "Avg Memory: $AvgMemory GB"
Write-Host " "
} |
$Clouds = Get-SCCloud
foreach ($Cloud in $Clouds)
{
$VMs = Get-SCCloud $Cloud | Get-VM
$VMCount = $VMs.Count
$TotalMemory = [math]::round((($VMs | Measure-Object -Sum MemoryAssignedMB).Sum / 1KB), 0)
$AvgMemory = [math]::round(($TotalMemory / $VMCount), 0)
Write-Host "Cloud: $Cloud"
Write-Host "VM Count: $VMCount"
Write-Host "Total Memory: $TotalMemory GB"
Write-Host "Avg Memory: $AvgMemory GB"
Write-Host " "
}
You will also see average memory usage of your virtual machines.

I suppose that your all Hyper-V nodes in Cluster has same memory size.

# Setting Jumbo Packet Size on Localhost
Get-NetAdapterAdvancedProperty -DisplayName "Packet Size" | Set-NetAdapterAdvancedProperty -RegistryValue "9014"
# Creating New Cim Session for Remote Host
$CimSession = New-CimSession -ComputerName S0134VMHOSTT02

Get-NetAdapterAdvancedProperty -DisplayName "Packet Size" | Set-NetAdapterAdvancedProperty -RegistryValue "9014"
# Creating New Cim Session for Remote Host
$CimSession = New-CimSession -ComputerName S0134VMHOSTT02
# Get Jumbo Packet Size on Remote Host
Get-NetAdapterAdvancedProperty -DisplayName "Packet Size" -CimSession $CimSession
# Setting Jumbo Packet Size on Remote Host
Get-NetAdapterAdvancedProperty -DisplayName "Packet Size" -CimSession $CimSession | Set-NetAdapterAdvancedProperty -RegistryValue "9014" -CimSession $CimSession
I hope that helps you to configure packet sizes easily.

I use Custom1 section in SCVMM to set expiry date for virtual machines.

| $Date = (Get-Date).AddDays(180).ToString("U")
$cp1 = Get-SCCustomProperty -Name Custom1
$VMs = Get-VM
foreach ($VM in $VMs)
{
$VM | Set-SCCustomPropertyValue -CustomProperty $cp1 -Value $Date
} |
$Date = (Get-Date).AddDays(180).ToString("U")
$cp1 = Get-SCCustomProperty -Name Custom1
$VMs = Get-VM
foreach ($VM in $VMs)
{
$VM | Set-SCCustomPropertyValue -CustomProperty $cp1 -Value $Date
}
I use System Center Orchestrator to check expiry dates.

You can use this script to assign logical network to your Hyper-V hosts.
For example, in this script, “Test_Logical_Network” is assigned to all servers in Test Host Group.

| $VMHosts = Get-VMHost | Where VMHostGroup -like "All Hosts\Test*"
foreach ($VMNode in $VMHosts)
{
$VMHostName = $VMNode.Name
$Job = New-SCExternalJob -Name "$VMHostName Logical Network"
$JobID = $Job.ID
$VMHost = Get-SCVMHost $VMHostName
$vmHostNetworkAdapter = Get-SCVMHostNetworkAdapter -VMHost $VMHost | Where ConnectionName -eq "VmNetwork_team"
Set-SCVMHostNetworkAdapter -VMHostNetworkAdapter $vmHostNetworkAdapter -Description "" -AvailableForPlacement $true -UsedForManagement $false -JobGroup $JobID
$logicalNetwork = Get-SCLogicalNetwork -Name "Test_Logical_Network"
Set-SCVMHostNetworkAdapter -VMHostNetworkAdapter $vmHostNetworkAdapter -JobGroup $JobID -AddOrSetLogicalNetwork $logicalNetwork
Set-SCVMHost -VMHost $VMHost -JobGroup $JobID -RunAsynchronously -NumaSpanningEnabled $true
Set-SCExternalJob -Job $Job -Completed -InfoMessage "Logical network eklendi"
} |
$VMHosts = Get-VMHost | Where VMHostGroup -like "All Hosts\Test*"
foreach ($VMNode in $VMHosts)
{
$VMHostName = $VMNode.Name
$Job = New-SCExternalJob -Name "$VMHostName Logical Network"
$JobID = $Job.ID
$VMHost = Get-SCVMHost $VMHostName
$vmHostNetworkAdapter = Get-SCVMHostNetworkAdapter -VMHost $VMHost | Where ConnectionName -eq "VmNetwork_team"
Set-SCVMHostNetworkAdapter -VMHostNetworkAdapter $vmHostNetworkAdapter -Description "" -AvailableForPlacement $true -UsedForManagement $false -JobGroup $JobID
$logicalNetwork = Get-SCLogicalNetwork -Name "Test_Logical_Network"
Set-SCVMHostNetworkAdapter -VMHostNetworkAdapter $vmHostNetworkAdapter -JobGroup $JobID -AddOrSetLogicalNetwork $logicalNetwork
Set-SCVMHost -VMHost $VMHost -JobGroup $JobID -RunAsynchronously -NumaSpanningEnabled $true
Set-SCExternalJob -Job $Job -Completed -InfoMessage "Logical network eklendi"
}
That will assign all VLANs in Test_Logical_Network to specific Hyper-V host.
