I worked with an Ubuntu 7.10 VM for several weeks and during that time the VM's .hdd swelled to ~14 GB. Since the project completed, I've deleted several gigabytes of unnecessary stuff, but the .hdd file doesn't shrink -- is it supposed to? Or is this what Parallels Compressor is for? "Run Parallels Compressor" under the actions menu is always greyed out. I've done some searching and seen that I need to be an admin user to run it... I have admin rights but of course Ubuntu doesn't use the root account so I need to be prompted for it or I need to issue a sudo command. Anyone able to get me on the right track here?
