Virtualbox/VMWare XP Guest Memory Requirements
 
I am trying to get a feeling of how much memory I need to run VirtualBox or VMWare smoothly (on Ubuntu 8.04 host with Windows XP as a guest).

I don't need too many Windows programs, but my laptop only allows a max of 2Gb (which is already installed).

I don't have XP now (or I could just try it), and don't want to purchase it and then be sorry. So, I was hoping that maybe I could get feedback from those with experience ...

Is 2Gb enough to share between host and guest OS? Is VirtualBox or VMWare better with memory? Any other relevant feedback?

Any help is much appreciated.

Hi, My vbox setup is set to use upto 512Mb and 128Mb graphics.

But the default is 192Mb and 8Mb. AFAIR.

Vbox has all the info on their site (wiki)

Cheers, Glenn

I have 2gb ram and have given XP 256MB. I only use XP for Napster but at least I have migrated fully to Linux now I can use VM's :-)

Thank you for your replies.

So, is the performance of Host and Guess OS OK with 256Mb or 512Mb? Are there times when things slow down significantly? Do you notice any slow downs with particular programs?

You need to assign as much RAM to the guest operating system as you would want to have in a physical machine running that operating system. This works on the assumption that the host machine you're using has more than enough RAM for itself.

In general, I wouldn't want to run Windows XP (for anything but the most basic things) with less than 512MB of RAM. Thus, that's the minimum I give it when running it in a Virtual Machine.

If your host machine has only got, say, 512MB of RAM, then you're effectively limited to 256MB RAM for the guest, since most GUI Linuxes require ~256MB to run comfortably (please don't flame me! ;)).

Since your host machine has 2GB RAM, I would say you can comfortably assign 768MB to Windows XP for it to run smoothly without impacting on your host OS too much.

As for whether VirtualBox is better than VMWare at memory management, the virtualisation software itself takes up an insignificant amount of memory; it's the virtual machines which suck up all the RAM, and there's no way around that, that I'm aware of.

Thanks pwc101. This is very helpful. Good general info, as well as specific suggestions. I will take the plunge, and start with 768Mb for XP. Thank you again for this reply.
