Wow, Unity on a VM? I haven't seen that, actually I haven't seen any Linux user in my current and previous employers that would start any X apps on a VM. Why start a browser there? Is it for testing the web pages in different environments? If not, then wouldn't it be more reasonable to start it on a bare metal (the machine you connect to the VM)? But it might be my bias, I'm one of those that install Linux on a company laptop on day one :) so I'm most efficient in the console.
