Can't access console in VM configuration

Hello,

I can create VM in phpVirtualBox

I can attach Ubuntu ISO image

I can start VM from ISO image

But I can't access strated VM Server console. In VM settings Remote Display is activated and have default settings and I write NAS server IP, because with localhost this is not working. But then I click the console button the empty screen is displayed. How to change settings to access started Ubuntu installation and interact with it.
