PowerCLI: Search VM By MAC Address

The below snippet is pretty useful for when you have a mac address conflict between your VM’s. The VMware alarm/flag does not tell you the VM that it MAC conflicts with so time to open up PowerCLI and run the below example


Get-VM | Get-NetworkAdapter | Where {$_.MacAddress -eq “00:59:59:c9:da:9a”} | select @{Name="VM";Expression={$_.Parent}},MacAddress | ft -AutoSize

PowerCLI C:\> get-vm | Where {$_.PowerState -eq "PoweredOn"} | sort Name | Select-Object VMHost,Folder,Name,MemoryGB,@{N="Memory Usage (Average Over 30 Days), %" ; E={[Math]::Ro
und((($_ | Get-Stat -Stat mem.usage.average -Start (Get-Date).AddDays(-30) -IntervalMins 5 | Measure-Object Value -Average).Average),2)}} | Format-Table -autosize -Property VMho
st,Folder,Name,MemoryGB,"Memory Usage (Average Over 30 Days), %" | Export-Csv C:\temp\MemoryUsage.CSV

$ = New-Object VMware.Vim.ToolsConfigInfo
$ = $true
$_this = Get-View -Id $vm.Id
