No, defrag for virtual PC is not the same as compaction. As the virtual PC can grow in size as you need more space, compation moves all the data to the front of the drive and frees up the slack space. So it then can grow as you need more space. But Defragmentation just moves all the data around in your virtual drive to make the files contigious and does not free up unused space.
If you look at the layout of a virtual disk when you first creat it, it only is as big as the space needed. It will automatically add more space as you create new data or install other programs.
