Though, from what I have read, I would not consider it a "virtual machine host solution" either. While I understand it runs image files, I don't think it's geared for several OS images, running concurrently. Again, note, I only installed - and when the image I had (passed by a friend) failed to run, I just removed it. In the end, my virtualization solution has been VMWare ESXi, and VirtualBox only on a Linux host. So, I reserve the right to be wrong. :P -- Tom Rhodes
