I cannot locate the command on VBoxManage or VBoxHeadless that will start a group of VM's in headless mode. Is there such an option?I want to start from the command line a group of vm's without having to start individually every VM.I stumbled upon this but the flag --groups is not working in my case.VBoxManage startvm  --type headless --groups My GroupSyntax error: unknown option: --groupsThe only way to start the group in headless mode is from the VirtualBox UI
