virtualbox.org

Hi!

Host:
CentOS 7.0
AMD FX 8350 8-core-processor
32GB Ram
Swap: 128GB

Graphic:
AMD FirePro W2100

Vbox:
Version 5.1.20
extensions installed,
guest additions installed,
all up to date.

Video Memory set to 256MB
3D Acceleration enabled.

Guest Win 7.
Start of Win 7 is OK.
Starting of some low-level apps works also.
After starting ptc creo (CAD-Software)

The machine is working, working, working.

After ca. 1-2min. the window is shown, but with wrong graphics.
(The order of layers is wrong)

Then the complete kde is freezing, only the mouse can be moved, but nothing else.

I must log in via ssh from another machine and kill virtualbox.
After that, kde is running normally again...

With disabled 3d acceleration, all works fine, but to slow..

Does anyone know the solution?

I deleted your duplicate post from viewtopic.php?f=6&t=82579. Please do not post duplicates again.

Programs like these have strict requirements for the graphics card specifications. Virtual machines will never be as powerful as the host, especially on the video side. They use after all a virtual graphics card, not your host's real graphics card. Applications that have high requirements on the GPU (drawing, 3D, games, video) are expected to not work as good as on the real hardware, if they work at all.

You only option is to pretty much wait for improved graphics support. I have no clue when this will happen or if it will happen at all.

Hi socrates,
I thought, it are two subjects, so I appended the one subject (slowly running app) to one thread.
At this thread, which I started newly, I have obviously a real problem with the 3D-Setting.
I think it is a real problem, vbox blocks my complete X /KDE on both monitors, when I start creo inside the guest system ...
So that I must login from inother machine with ssh to shutdown vbox.

I think, this is not a question of velocity.

To your answer:
The machine, which I use, is very strong.
Creo is running fluently on machines, which have half the power.

Maybe, that somebody else here has experience with using 3DCAD at vbox?



Greetings, Holger

In case you missed the gist of the answer:

But the virtual machine you use, is really, really weak.

And, no, it was the same issue.

OK, here a short report:
After changing the graphic card,
(now a gamer card, GeForce GTX750Ti4GB)
and installing the nvidia-drivers, I am using creo on win 7 on centos 7 without any problems ....
Great!
It was fortune, that I tested vmware firstly, but I suspect,
vbox would work as well.
May be, that I will test vbox in future, now I have no time.
