Not impossible, but not really appropriate to this forum. You need to talk to a Parallels group to figure out how to access the virtual ports on your guest image from your host image, and vice versa. It’s definitely not impossible—I used to do it with VMWare all the time. And Docker (which runs in VirtualBox on Windows) can most certainly do it.
Or else you can spend some time with the Parallels user manual: http://download.parallels.com/desktop/v6/docs/en/Parallels_Desktop_Users_Guide/31974.htm
