I run virtualbox on machines with 8gb and more ram. with only 1gb, if you run a single 512MB VM, you'll only have 512MB left for your regular system too. what are you going to install in a 512MB VM other than very stripped systems? -- john r pierce 37N 122W somewhere on the middle of the left coast
