powercli Get-VM 不匹配标签

Question

I am using Tags to filter VM / identify special configuration.

Get-VM -Tag TEST

Now I want to get all VMs NOT matching a tag .... Is there a way to do that without an extra loop to remove all items matching the Tag ?

Answer 1

As it seems, no. But using another loop is not a bad solution.

Should be something like:

Get-VM -Name * | ?{$_.Tag -ne "Test"}

Or if VirtualMachine doesn't have a Tag property, you should try with Get-View :

Get-View -Name * | ?{$_ .Tag -ne "Test"} | Get-VM

Answer 2

I was looking at this, and I used the -contains / -notcontains comparison operator instead of -eq / -ne , as it always returns the a boolean expression. If you have more than one tag, it might not work properly.

$VMs = get-vm 

foreach ($VM in $VMs){
    If (((Get-Tagassignment $VM).Tag.Name -notcontains "Prod"){
         Whatever you want if it doesn't contain prod.
    }
}
