I have installed Windows 7 (as guest) using Virtual Box on my Ubuntu 13.04 (as host).
Everything was OK except some network problems. I have no problem with browsing websites in guest OS (windows 7) but there is another problem.
I've installed Visual Studio 2012 on the guest OS and tried to connect to a TFS server which is on my LAN. VS can't connect to the TFS server most of the times. But sometimes it connects and very soon it stops responding. It seems that there are some problems with such protocols. I have the same problem with Plastic SCM (a distributed source control software) when I want to sync source control repositories.
I tried both
Bridge modes on Virtual Box but none of them works.
