I just installed Ubuntu 13.04 (daily, full updated) and installed Windows 8 in virtualbox.

When Windows 8 is running a have huge performance issues on Ubuntu. Last week I had the same setup with Ubuntu 12.04 (full updated) and I had no problem with the overall performance.

Where is the problem and how can I fix it?

PC:

ubuntu 13.04 x64
4 GiB RAM
4x3,1 Ghz Intel Sandybridge
On-board Graphics

VBOX:

Windows 8 x86
1 GiB RAM
1 CPU
Graphics memory 128MB
Guest-extension is installed
3D-Acceleration active

I believe there is a package called virtualbox-guest-utils. Install it with sudo apt-get install virtualbox-guest-utils. This should get the virtualbox drivers. NOTE: You need the latest virtualbox to support guests with recent linux kernels.

I had to do a few things:

install guest additions

install dkms (dynamic kernel module support):

sudo apt-get install dkms

add the line:

vboxvideo

to /etc/modules.

I had already installed gcc prior, you may need that to install the guest additions. I installed the guest additions by the virtualbox menu, under devices; I didn't use apt-get.
