OracleVM is an excellent alternative to Virtual PC and other client-side virtualization tools.It's mostly open source, and supplies the ability to run virtualized OS's from a lightweight and incredibly user friendly environment.It provides comparable features to other solutions that target the same market, and goes above and beyond in some aspects.Like I said in one of my other reviews, one of the biggest "sellers" for this software, is that it's free. You really cant beat free from a price perspective.
Room for Improvement:
Even with the "add-ons" tools that come with OracleVM, some features that are available in other solutions, are simply not there.One mentioned in another review, is the dragging and dropping of files between host and VM. Another major issue, is that you technically cannot use this software to host a remotely accessible virtual machine without using alternative access software such as VNC or RDP, depending on your virtualized OS.Back when I started using OracleVM, Sun Microsystems was a separate company and it was called Virtualbox. I stopped using it for one reason and one reason only, because Oracle closed off portions of the code, creating an OSE (open source edition) and a CSE (closed source edition) of the software.
This pushed me away, as it used to be wholly open source.
