VBoxHeadless allows non-headless VM to start

[ToddAndMargo]

Hi All,

Please do not allow

/usr/bin/VBoxHeadless --startvm $VM_Name

to start a VM if the VM's display is not configured for headless. You have to use "ps" to kill it and corruptions can occur in your VM.

Many thanks, -T

What do you mean by "not configured for headless"? You don't have to kill a VM but you can shut down it with VBoxManage controlvm VM_NAME powerdown.

Replying to frank:

Under /usr/bin/VirtualBox, "Settings", "Remote Display" tab, "Enable Server", do not run headless if this is not enabled. This because VRDP will not work with it.

I used "/usr/bin/VBoxManage controlvm $VM_Name acpipowerbutton". I don't remember it working, so I reverted to "ps" and "kill", since I could not VRDP into it.

This VM setting is independent of the operation of VBoxHeadless and we don't intend to change this. As I wrote, the VM can be easily terminated with VBoxManage, and VBoxManage controlvm ... poweroff will work in any case. VBoxManage controlvm ... acpipowerbutton will not work if the guest does (currently) not handle ACPI events.
