Would it be possible to set up Parallels to use an existing bootable partition of Ubuntu as a virtual machine (like setting up a Windows partition with boot camp)?
AlbertM No it is not possible. It is possible to create bootable disk image based on the partition. Parallels transporter supports: Ubuntu® Linux 7.10, 7.04, 6.10, 6.04, 5.04 http://www.parallels.com/download/desktop/ (here you may download Parallels transporter) http://download.parallels.com/desktop/v4/docs/en/Parallels_Transporter_Users_Guide/index.htm (general documentation)
