Virtual Box. Very Slow Video.

I have an AMD Phenom Quad-Core, 3GB RAM and an 8800GT.

I installed VirtualBox and setup XP. I turned on virtualization and installed the guest applications. I gave the VM 1GB RAM and 128MB video RAM.

I know there is no 3D acceleration, but last year I did the same thing and did not notice this problem: Video is very slow. Playing a video on Youtube or Netflix is like watching a slide show.

Any idea how to speed things up a bit?

Thanks.

Re: Virtual Box. Very Slow Video.

Did you enable AMD-V?

Are you running the latest VirtualBox? 2.1.2 had a bug that made many things slow.

Yes to both questions.

Thanks for the help. I guess I'll uninstall and get the official stable release from the website.

Give what you have. To someone, it may be better than you dare to think.

Well, installing 2.1.4 from the Vbox website improved Youtube considerably. Now I have something to work with. I'll try tweaking settings and keep searching the web for similar problems.

Thanks for the help.

Turned off PAE/NX and tried 32MB and 64MB video RAM. Still pretty slow video. Maybe Netflix is too much for a vm.

Re: Virtual Box. Very Slow Video.

I'm wondering: maybe I should be using 64bit Arch if I'm going to virtualize.

That shouldn't make a big difference.
Do you have acceleration turned on in the vbox configuration? Try toggling it.
Is the seamless mouse capture working as well as everything else that indicates that the vbox additions are installed properly and working?

Tried toggling 3D acceleration. Everything works perfectly: I can change resolutions, I can even go full-screen on my 22" monitor. Seemless works fine. It's just very slowly updating the screen and things like streaming video.

I know Nvidia seems to have problems with 2D. I'm beginning to wonder if it's an Nvidia problem.

Re: Virtual Box. Very Slow Video.

May be a driver issue indeed, it doesn't hurt to try the open source driver smile

Re: Virtual Box. Very Slow Video.

Well, I could try the Nouveau driver, I suppose. Don't know what progress they've made on it so far.

Re: Virtual Box. Very Slow Video.

Funny thing: I turned off AMD/v and it's running better. Netflix is almost watchable now.

I wish they would just let people stream from whatever OS they want. All this DRM crud is annoying. Well, I can always boot to Windows to watch movies, I guess.

Also funny: Hulu and Youtube work fine. Netflix is slow and choppy. I really just wanted this VM for Netflix. Guess I'll stick with Hulu.

Re: Virtual Box. Very Slow Video.

Well, funny things just keep happening. I decided -- after reading a post -- to try Netflix on Firefox. It actually runs much better on FF than IE. Go figure.

Go figure? The only thing Internet Exploder is good for is incompatible sites anyways tongue You should have used FF first! big_smile

Anyways, can you use this to watch in Linux?

Yeah, no one has been able to get boxee working for Arch...

Oh, wait!

OMG. You're a genius.
