How much memory (RAM) should I allocate to the Virtual Machine?

I want to set up Ubuntu in a VirtualBox virtual machine. Because this is a virtual machine, I specify exactly how much RAM and video RAM the virtual machine gets.

I am looking for recommended specs for Ubuntu 12.04. I've found specs for minimum requirements, but I want to have a nice experience, so I don't want to give it just the bare minimum. However, since this is a virtual machine, I don't want to give it more than it will use, since it will be running alongside other programs on my computer.

Where can I find recommended specs for Ubuntu 12.04?

I know that this is probably not the answer that you're looking for.

I don't know if there is such a document, or specs. Just to give you an idea, I'm running Ubuntu 12.04, and I have 3 different VM inside: Windows 7, Ubuntu 12.04( for testing purposes), and Lubuntu 12.04. I gave each of them the same resources, and I normally have them running at the same time. And the system is running smoothly.

enter image description here

My system specs are:

  • Core 2 Duo 2.4GHz
  • MSI G41 MB
  • 8GB DDR3 RAM

Again I know that this is probably not the answer that you're looking for, But I hope that it helps.

Note: I'm running VMWare Workstation 8.02, and I'm using the default without any issues. The video driver memory is set to 16MB by default. You need to edit the vmx file to increase the amount of RAM. Add this: svga.vramSize =

If you use an older version, you will have more control over the video RAM. For what I need 16MB is enough.

How much video RAM do you give your VMs? I guess that was the main thing -- I've given it 1 GB of system ram, but my actual hardware doesn't have a terrible amount of RAM, so I want to be judicious with how much video RAM I give the VM on top of the gigabyte I've already given it. – user1359 Sep 11 '12 at 13:58
Well 128MB appears to be the maximum video memory setting in VBox, so it's a moot point I guess. – user1359 Sep 11 '12 at 14:18
If you need that much video RAM, you'd better use VirtualBox then. And the best part about it, its FREE :) – Mitch Sep 11 '12 at 14:21
How much might I actually need? That is the question :) – user1359 Sep 11 '12 at 17:23
@user1359 The amount of video ram that can be given to a VM is often limited. 128MB is enough for it. The real problem is not the Ram but enabling other features such as 3D-accelerations and etc. For those features, you need to used virtualbox-guest-additions. FYI, my laptop's video RAM is 256MB only. – Anwar Shah Sep 12 '12 at 2:01
