Even though Construct 2 runs fine in a VirtualBox VM, Chrome/Firefox 10 struggle a bit with some of the more complex games in the Arcade. However, I just turned on Bridged networking (in the VM settings) and test games run great using Chrome/Firefox 10 on Fedora.
So, thats an option for anyone in my situation: Develop in Windows VM, test using native Linux web browser(s).
Haha.....Thanks for the solution. Since there's no native construct 2 for linux yet (hopefully in the future) this was exactly what i was looking for and i set up a shared folder between the host on guest to export final project. Thanks!!
