Ubuntu in Virtual Box - too slow


Recommended Posts

Out of curiosity tonight I installed Ubuntu as a virtual machine using Virtual Box. It runs fine, it's just not very responsive and very slow. I can't browse the web using Opera at an acceptable speed, for instance. Is this to be expected from running it from Virtual Box or is there anything I can do about it?

I allowed 512MB of memory to Virtual Box and 32 MB of video memory, a lot more than the recommended basic settings.

Such is the limitations of running a virtual machine, for the most part.

It runs pretty speedy as a LiveCD, right?

Well I've seen Fedora 8 run a lot better on a VM, on a slower computer too, so I was wondering. Didn't try it on LiveCD yet.

I too use VirtualBox on my Ubuntu, running Vista, XP and Xubutu. Most of the time they all run as speedy as to be expected from a virtual machine. But every now and then I too experience slowdowns. I then just shut down the virtual system and start it up again. This always fixes it. Annoying yes, and do not know where or why this happens.

Hope this solves your problem.

I haven't really used Virtual Box, but I recently had Ubuntu on VMware, and it was speedy. I recommend trying out VMware. To be honest though, I think it unlikely that Virtual Box would make it slow - but I don't know what else could be wrong.

It does run ok on a LiveCD. Messed around trying to setup internet connection for 15 minutes and gave up. :p Maybe Virtual Box runs bad under Vista?

I've only found Windows to virtualize well (XP runs fast with VB, under Kubutu 8.04 and AMD-V enabled)

I have Ubuntu 7.10 running under VMWare on Vista, and it takes ages to load, but not too bad when it eventually does. Not nearly as fast as the real OS, but probably on par for a VM.

At one time, I had XP 64-bit running as a VM in VMWare, and that was super fast.
