virtualbox.org

new to VB so I have lots of questions, I apologize if this has been addressed before but searching through the forums docs i did not see it...

How do I change a CD with VBoxHeadless when the Guest is booted?
VBoxManage modifyvm vmbox_01 -dvd /balh.iso wont work because it says the VM is currently in use

Have a look at the
VBoxManage controlvm <name> dvdattach ....
command.
