VBoxManage list vms

Info: includes hidden VMs created by Vagrant

Delete VM

VBoxManage unregistervm VMNAME --delete

Delete ALL VMs

This PowerShell one-liner will get all VM names from their folder names, then delete every VM. Just update your path to where your VirtualBox VMs are stored:

(Get-ChildItem 'D:\VMs\VirtualBox').Name | ForEach-Object {VBoxManage unregistervm $_ --delete}

List forwarded VM ports

VBoxManage showvminfo VMNAME --machinereadable | Select-String -Pattern 'Forwarding'

Note: Select-String is a PowerShell command
