Hi All,<div> I am trying out virtual box on a Dell XPS Laptop running Windows 7, Pentium i7 with 8GB of RAM and NVidia Optimus as the host and Ubuntu 12.04 as the client system.</div><div><br></div><div>Installation and setup was really easy, the only thing to watch for was 3D acceleration. </div>
<div>To fix this I had to run Virtual Box with the High-performance NVIDIA processor as default. If you don't do this, mouse response is good but there is a significant keyboard lag!</div><div><br></div><div>Multiple cores work nicely and the build happily runs with 8 processors and 2048Kb of memory without affecting the host system too much. It is incredibly fast compared with a Visual Studio 2010 Express build.</div>
<div><br></div><div>I am pretty sure that my OpenMesa OpenGL setup is Ok as running glxgears gives</div><div>289 frames in 5.0 seconds = 57.650 FPS</div><div>294 frames in 5.0 seconds = 58.776 FPS</div><div>296 frames in 5.0 seconds = 59.177 FPS</div>
<div>Which I think is quite good for a VM on a laptop!</div><div><br></div><div>Running VTKBenchMark - NOTE: This is a debug build</div><div>Building Fractal ... (this may take a minute or two)</div><div>Smoothing...</div>

</div><div>But still excellent - I would think a release build may be as fast as this in the Ubuntu client.</div><div><br></div><div>When it comes to running VTK programs (Python and Native C++) I see some issues:</div><div>
1) OpenGL Warning: No pincher, please call crStateSetCurrentPointers() in your SPU - from a search on the web this is almost certainly a Virtual Box issue so nothing can be done about it.</div><div>2) If you move a window with a VTK object in it then the panel containing the window lags and will ultimately catch up with the window and reseat itself. This is an issue because if you open dialogs etc. they stay behind the main window and thus are obscured. Curiously QtCreator and Eclipse work normally so I think this may be VTK issue. <br clear="all">
<div><br></div><div>Has anyone any experience with this kind of setup and can give me some advice?</div><div><br></div><div>I must admit that overall I am impressed with the Virtual Machine. I have usually dual booted my machines.</div>
