Clean VirtualBox virtual machines used by Chef on converge

From time to time I keep getting strange behavior, on local PC, with virtual machines used by Chef, maybe after a ChefDK or VirtualBox update.
Some VMs do not get destroyed properly, or maybe more than one VM is created for the same cookbook.
The following PowerShell script can be used to destroy all VMs for a Chef cookbook; it must be used from the parent folder of the cookbook, using the syntax:
.\clearCache.ps1 my_chef_cookbook .
And here the script clearCache.ps1, located one level above the cookbook, in order to be usable with all its siblings:

[CmdletBinding()]
param(
[string]$cookbook
)

# VBOX_HOME is a user environment variable specifying
# where the VirtualBox VMs are stored
# Something like C:\Users\[your_user]\VBox_VMs

$dir = (pwd).Path
cd $cookbook
Write-Output “Removing folder content for .kitchen”
rm “.\.kitchen\” -Force -Recurse

Write-Output “Power-off VMs”
((& ‘C:\Program Files\Oracle\VirtualBox\vboxmanage’ list vms) | `
  % { ($_.Replace(‘”‘,”) -split ” “)[0] } | ` # Replace double quotes with nothing
  ? { $_.Contains(“kitchen-“) }) | `
  % { & ‘C:\Program Files\Oracle\VirtualBox\vboxmanage’ controlvm $_ poweroff }
Write-Output “Delete VMs”
((& ‘C:\Program Files\Oracle\VirtualBox\vboxmanage’ list vms) | `
  % { ($_.Replace(‘”‘,”) -split ” “)[0] } | `
  ? { $_.Contains(“kitchen-“) }) | `
  % { & ‘C:\Program Files\Oracle\VirtualBox\vboxmanage’ unregistervm $_ –delete }

Write-Output “Delete the VMs again, just in case we previously had an error …”
rm “$($env.VBOX_HOME)\kitchen-$cookbook*” -Force -Recurse

Write-Output “Destroy kitchen”
kitchen destroy
rm “.\.kitchen\” -Force -Recurse
vagrant global-status –prune
Write-Output “Done”
ls
cd ..

Note: Be aware that when copy-pasting, the quotes and possibly other characters get messed up by WordPress, you’ll have to replace them.
