To speed up any VM, you can:
For a comprehensive list of approaches to increase VM performance, have a look at this article http://www.hanselman.com/blog/VMPerformanceChecklistBeforeYouComplainThatYourVirtualMachineIsSlow.aspx
Having very slow perform when running Ubuntu 12.10 and 13.04 in virtualbox? It’s because Ubuntu can’t use graphics card for acceleration, ubuntu uses CPU for rendering graphics trough LLVMpipe. It makes running ubuntu in virualbox really slow.
To check if your Ubuntu 12.10 or 13.04 guest is using 3D acceleration
You should see something like this
If you see “Not software rendered” and “Unity 3D supported” both say no. This means Unity is using slow LLVMpipe.
To enable 3D supported, fist you will need to update linux-headers
Now insert vitualbox guest iso from devices and to install manually
Insert vboxvideo to /etc/modules
Add “vboxvideo” at the end of the file
Reboot the machine
The other answer is good, but the link with more information seems Microsoft-centric.
This link http://blog.jdpfu.com/2012/09/14/solution-for-slow-ubuntu-in-virtualbox has a Win7 host, Ubuntu Guest solution for VirtualBox with specific VirtualBox settings. It is about running Ubuntu Guests too:
Disk I/O - virtIO, if possible; SATA if no other choice
Anyway, hope this helps.
BTW, How do I improve the performance of my VirtualBox guest? is a similar question with slightly different information.
