I just wanted to say that Virtual Box has been a wonderful tool I use every day in my development environment. I have a Windows XP guest, a Fedora Core 11 guest, and a Mikrotik Router OS guest. I use various network features like NAT, Bridging, and Internal. All these guests run flawlessly together, and have very little impact on the overall performance and stability of my laptop providing the VIrtualBox Services. Clearly, a lot of energy has been spent making sure that CPU hardware virtualization support works great, and I just wanted to thank all the developers involved on this project.
For a product that I use for free every day, I have no complaints. That's not because it's free, but because it works. Every day.
Thanks again.
