Hi. I installed Windows 8 Consumer Preview in VirtualBox. It is my first time using virtual technology so I have a couple of questions.

1. Do I install my GPU/Audio Drivers inside VirtualBox (eg Catalyst Drivers)?
2. What should I do to improve the sluggish performance? I already set 2 GB Ram.
 
I use 2 virtual cpu cores then 2GB memory and it works well for me. Install the guest additions as stated by the other poster. Turn on 2D or 3D if you want to get Aero and then switch to the MS graphics driver in device manager to get rid of the adapter error.

PS: The 3D graphics driver in the guest editions has to be installed in safe mode.
 
My windows 8 just broke. It's stuck at "Attempting Repair" loading screen
 
With Virtual box, I had to give it two cpus to get it to install properly. Guest additions is working for Win8. and it Win7 drivers worked for the most part on the laptop I was trying it on (bare metal for the lappy).
 
I think part of the reason for the apparent sluggishness is the video driver used in virtualbox locks you into a 64 hz refresh inside the VM. I suspect that's causing some of the lag and flicker issues I'm seeing. I gave mine 6 cores at 90% and 2 gigs of ram, and it's still feels laggy at times like I'm using remote desktop.
 
Has anyone been able to solve the windows 8 flicker in virtual box. When I install additions, everything flickers and just makes it unusable.

It has been working for me flawlessly with guest additions in stalled. I am using ver. 10.1.8r75467 of VirtualBox. I did have to give it two cores to get it to install correctly though.
 
Anyone actually look at the virtualbox forum.... this stuff has been covered multiple times.

You don't need to install any video/audio drivers in Win8, VBox installs its own. Make sure you install Guest Additions and Extension Pack. If you're not getting full screen resolution, check this.

Win8 runs fine even with 1GB ram, any sluggishness is due to it being a Preview version. Otherwise, Win7 & Win8 run just fine as VMs under 64-bit Ubuntu.
 
I installed the extensions, but that still doesn't fix the flicker. Has anyone got direct3D acceleration to work in windows 8 under virtualbox without what I showed in the video?
 
I've not seen this flickering before. What OS is your host? Have you tried running other guest OSes?
 
Installed the new virtual box released on april 2nd. Still has the same problem. 64bit guest and host.
3D/2D aceleration enabled. Installed new extensions along with the new version. The guest additions don't allow you to disable 3D acceleration. I was hoping this would be fixed. Get crazy screen flicker when I try this. Works fine without additions, but its slow.

Anyone know of any fixes?

I have seen the flickering issue when the host machine has nVidia graphics. On machines with ATi/AMD, it does not seem to do it.

I'm using nvidia. I was researching and found another site that talked about this issue and said there is no fix at this time.
 
I seem to have solved the screen flicker issue. I'm not certain what the secret sauce was but here are the steps I took:

1. Create new VM for Window 8. Don't power it on yet.
2. Increase virtual CPU's to match your physical CPU count.
3. Enable 3D acceleration.
4. Select Bridged Networking (probably unrelated).
5. Install Windows 8
6. Run Windows Update and install everything (it's in Control Panel).
7. Shutdown and disable 3D acceleration.
8. Boot up and install VirtualBox guest additions. When asked if you want to trust Oracle drivers in the future, check YES.
9. Reboot, make sure everything still works.
10. Shutdown and enable 3D acceleration.

That seemed to do it for me. Metro seems really smooth now, Youtube videos play smoothly.

Best of luck!
 
You might try disabling the 2D check box leaving the 3D check box checked.

I am running Win 8 in vbox with no issues at all. The specs are Windows 7 64bit host, Nvidia 460GTX graphics card and AMD cpu, 2 cores enabled using VirtualBox 4.1.18 with the same guest additions, 256MB of video memory and 2048 of ram. To be honest windows 8 guest runs better than my windows 7 guest. The only thing that doesn't run, that I know of, is the pinball Fx game in the launcher. Solitaire works but I haven't tested any 3d apps yet outside of those two.

On another note if you make a mistake installing the guest additions make sure you remove them by going to the guest machine control panel-programs and features and remove them from there before reinstalling them. Some say that the reinstall without removal causes issues.

My 2 cents that is worth a penny.

this probably isn't that helpful but VMware workstation works great with guest OS's, especially with 'VM tools' installed. haven't has any issue with any guest OS (winXP, win7 32/64, win8 64, Ubuntu 64, Mint 64).
i'm usually conservative when assigning resources (2 cores, 2-4GB RAM, 40GB disk).
the host system is in sig (PII 1100, CHV & 16GB RAM).
