I wanted to use the build-factory provided vmware image to do some development, however this proved difficult since the image is using a fixed size of 250 MB disk. Would it be possible to make the build-factory use a disk type that allows to increase in size?
If the Superpack doesn't work for you, you can do what I do. I have two vmware drives; one for BeOS and another to build Haiku onto. I set up bootman so I can boot to whichever one I want.
