I have a virtualbox headless VM running on CentOS 7. I can show the console of the VM by opening up the virtualbox manager, right clicking the machine, and choose "Show". Is there a way to do this (pop up the console of the headless guest) without opening up the gui manager, i.e., from the command line? I've tried most likely commands for vboxmanage but get errors or the wrong result. I also asked on Unix & Linux without success. On superuser there are responses to similar questions, but they all relate to connecting to the guest via ssh or rdp. I want to get the functionality provided by the gui "show" tab via the command line.
