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 Group"
Syntax error: unknown option: --groups
The only way to start the group in headless mode is from the VirtualBox UI
