WINE "only" provides the application programming interface to allow a windows program to run under Linux. Virtualisation usually means running a "full" computer inside a computer. There's a considerable overhead with the latter, but the advantages are quite considerable. With a VM you can run pretty much anything inside the application (some restrictions apply) but you need enough memory, cpu and disk to run and hold your host machine and the guest *simultaneously*. With WINE there is just the WINE program and the specific windows programs and libraries you want to run that you need on disk and in memory. Much more lightweight. There is also the philosophical side which includes the implication that running applications under WINE and/or VM puts less pressure on application developers to create Linux-native versions of their applications. There are also security issues with both. With WINE, the windows application has access to your host machine and thus any files that you as a user have access to. If the windows program allowed you to run a trojan/virus then it could wipe out your valuable data. With a VM the machine is encapsulated inside a "box" that keeps it safe.. ..safe-ish.. with the CPUs that have the VT stuff it's potentially possible for an application running inside the VM to "break out" and execute code on the host. http://theinvisiblethings.blogspot.com/2006/07/blue-pill-hype.html Cheers, Al. -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
