Hi, I find some bug:
on my 32-bit opensuse 11.2 host with PUEL VirtualBox 3.2.4r62467 I run guest 32-bit ubuntu 10.04 in console(command line interface, cli), and it is slow down scrolling console, compering with same 32-bit debian guest console, for example when I run 'man' pages, or read file by 'less' or 'cat'.
Maybe it is ubuntu drivers bug or specification.
Settings for my ubuntu guest: http://pastebin.com/qm4rwju5
Have any ideas?

The slow drawing performance is because Ubuntu switch into VGA16 mode (for virtualization this is the worst graphics mode you can imagine) if no graphics card of Intel, AMD or nVidia is found.
You can ssh or rdp in and it is smokin fast

Ok, it is possible to turn off it switch to VGA16 mode, and work like in debian console?

I have not found a way to change the Ubuntu 10.04 to work differently yet. Used to be able to set the parameter in the boot menu but they have changed a lot of things that we used to be able to do.

Ok, thanks. I find some solution for this.

If you find a way please post it here. I am sure everyone that uses Ubuntu 10.04 Server would appreciate it.
Since I ssh into mine I don't see this problem but other that are using the CLI direct would.

Yes, sure if I find solution, I post it here.

I find some solution: http://ubuntu-virginia.ubuntuforums.org ... ?t=1484385, it works.

I find one one more solution: http://ubuntuforums.org/showpost.php?p= ... stcount=10.
With this solution I have 1024x768 screen without slow-down scrolling like by default.
Try and enjoy this!

Very well done savgur. This will make a lot of people happy I am sure.
I have not tried the second one yet but the first one works well.

I can confirm http://ubuntuforums.org/showpost.php?p= ... stcount=10 works great, except that on step 6, if Ubuntu is the only OS (which usually is the case in VirtualbBox), you'll not find the file /boot/grub/menu.lst . Instead you'll have to modify /boot/grub/grub.cfg and find a line starting with "linux /boot/kernel.... " instead of "kernel /boot/....".

I tried the 2nd link first and it didn't work...
The 1st link worked for my setup (http://ubuntu-virginia.ubuntuforums.org ... ?t=1484385).
