Make sure your laptop is connected to the same router as your PC.
Simply follow the same procedure as you did to setup Oracle connection from your PC. Your virtual machine is a separate computer for all practical purposes. You can access the virtual machine server the same way from laptop as you do from your PC.
Do an entry in the host file of your laptop
192.168.x.x linux.server
Where 192.168.x.x is the IP address of the virtual machine.
You should now be able to access Oracle through the browser.
http://linux.server:8000
Make sure you disable XSS
