Attack of the virtual machines previous: A web server in 30 lines of code next: The quote generation DSL I just found out that I have too many virtual machines around. Right now I am working on three plus the host machine. I have the Mac's Windows 2008's Fusion VM as well, come to think of it. Comments 03/31/2008 03:48 PM by Tolga I love the concept of working in VMs, whereby not having to "muck" with your core "host" OS. However, I always end up finding the performance too slow (I have used VMWare Workstation so far). I usually have 4GB of RAM in a high end laptop and dedicate about 2GB to the guest OS. Forget about having more than one VM running at a time - impossible performance... I am genuinely interested in finding out whether you can actually effectively work in VMs to do serious development. If so, I wonder what I could be doing differently or better to get acceptable performance... Are there any "gotcha" pointers? Thanks 03/31/2008 04:02 PM by Ayende Rahien Tolga, I did development on a 512MB VM in a 1GB second hand laptop. It works, not fun, but it works. I tend to do most of my dev on the host machine, with the VM serving as servers, integration and CI Comments have been closed on this topic.
