Good Ridance, Vmware

Just as MIT announces a huge site license with Vmware, I've decided that for my personal needs, I can do better. I've been using Vmware Server to run a Windows instance along side Linux. I use it for web browsing and for running Office. These sorts of applications are far easier to use with a screen reader on Windows than they are on Linux.

I've always felt dirty using Vmware. First, it's not open source. Second, it just really feels like a bad fit. The architecture is very complicated. Server wants me to trust its security model. Also it depends heavily on my local libraries and precludes me from upgrading my Gnome or GTK installation. There are command line tools for manipulating the configurations, but they are hard to use and don't really seem like a very supported interface. Then, there is the plans for new Vmware Server which relies exclusively on a Java component to interact with the virtual machine. It seems far more complicated, brittle and harder to understand. So, I started looking for an alternative.

I've settled on Virtual Box. The major downside is that it does not support 64-bit guests. It's much simpler than Vmware; it doesn't depend on a network IPC mechanism and it uses the OS's security model. It's mostly open source: there is an open source version and there is a version with a few more features that is not open source. On one machine I can use the open source version; on another I need the USB support from the closed source version. It has kind of a rugged user interface, but one that meets all my needs. I seem to be very happy. Thanks to Marc Horowitz for pointing it out.



Why Virtual Box over Xen? (I had a angsty "which virtualization platform should I use" post a few weeks ago.)
Xen is my server virtualization solution. However I don't want to run Xen on a laptop (ACPI support sucks is the biggest problem) and generally Xen works much better for servers than workstations.
I do run xen in egg-crate and would not consider virtualbox there.
And Sun recently bought VirtualBox; I will speculate that the trends with Sun's other software products suggest that they may open source the closed source parts at some point in the future.
