Note: The Windows SDK landing page is here: SDK/MeeGo SDK for Windows. That includes the installer and support for Windows XP and Win 7 (32-bit). It is also based on QEMU VM (not VirtualBox)
QEMU will not work within a VM.
When the distro has been installed, it is time to have the VirtualBox Guest Additions compiled and installed.
sudo apt-get install dkms gcc(This will install everything needed to build the guest additions, replace with the command needed for your distro, the path on a *ubuntu machine is most likely.)
sudo ./path/to/cdrom/VBoxLinuxAdditions-x86.run(In *ubuntu the path will most likely be "
/media/VBOXADDITIONSsomethingsometime") When the additions are installed, you can restart the virtual machine by issuing sudo reboot in the terminal.
When everything above is done, you can go to: SDK/Docs/1.0/Getting started with the MeeGo SDK for Linux and follow the guidelines there.
