Gues additions seem to been installed correctly.
Can you give your graphic card 32 Mb of memory. It's the only difference that I see with my setup that does work correctly in fullscreen or seamless.
How to check if video guest additions are installed
Looks like guest additions have not been correctly installed. Check that windows is using Virtualbox Graphics Adapter as it's display driver. If it isn't try to reinstall the guest additions and report back any problem that it displays.
You can check it using the Device Manager on windows. If you are using XP, you can reach it this way:
- To open Device Manager, click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager.
Other windows version have it placed in another places, but it's always there ;).
Virtual Box guest additions do not install per default. We do have to manually install them as outlined here:
In a non-GUI (server) guest we may not need the guest additions if we do not need additional features provided with them (e.g. support for USB2). Then we simply do not install the guest additions that come on an .iso image installed on the host after installing the virtualbox-guest-additions-iso package there with
user@host:$ sudo apt-get install virtualbox-guest-additions
When having installed the version from the Oracle repository (see this question) the guest additions .iso is installed on the host by default.
Installing guest additions is done from an install script on the .iso to compile and insert the kernel modules provided. Mounting the .iso image can be done from their location on the host, or alternatively by installing the guest additions .iso from the Ubuntu repository with
user@guest:$ sudo apt-get --no-install-recommends install virtualbox-guest-additions
We should not install recommends in the guest to avoid installing virtualbox-ose package too.
Note that the guest-additions version from the repositories may be of an earlier version than Virtual Box when installed from Oracle. This will likely work but it is not recommended.
After having installed the kernel modules guest additions .iso can be removed from the guest OS. To uninstall guest additions from the guest we may remove the kernel modules manually, or run the uninstall.sh
script located in /opt/<VirtualBoxAddtions-x.x.xx>/

You can have the ubuntu server console in VirtualBox start at a resolution that your graphic card supports via the virtualbox environment.
Quick Steps
Check the resolutions your graphic card supports via the VirtualBox Environment (VBE).You should be able to find that out by issuing the command '
vbeinfo
' in the GRUB console (hit the C key when the GRUB boot menu shows up).Pick one resolution, then open '/etc/default/grub' (e.g.
sudo vim /etc/default/grub
) and change the line#GRUB_GFXMODE=640x480
to something like thisGRUB_GFXMODE=1152x864
(where 1152x864 should be your custom resolution which is also supported by your graphic card).Now run these two commands one-by-one:
You should now see your VM's console in the custom resolution that you just set.
(PS: As Javier Rivera said, full screen resolution may not be possible.)
