I successfully installed "android-x86-2.2-generic" in a VirtualBox machine. I took the iso from here: http://code.google.com/p/android-x86/downloads/detail?name=android-x86-2.2-generic.iso
Everything is working properly, even the network (FYI: Bridge with PCnet-PCI II).
I'm using it to have a faster emulator (and it really is), and now I need to simulate SMS and Missing Call. Usually in AVD emulator I use a telnet session to localhost:5555/n. But in the VirtualBox, even if I connect to 192.168.1.4:5555/n nothing is working, only a black screen.
I don't even know if it is possible to use telnet on Android-x86... do you know? Is there an other way to simulate SMS and Missing Call without telnet connection?
