Here's the easy way, such as it is: Start the VM and log in as root. Run the software updater till it's up to date. In the VM, go to System->Administration->Security Level and Firewall. In the SELinux tab, set SELinux to Permissive. In the PD menu, select Virtual Machine->Install Parallels Tools... to mount the disk image. Open a terminal, and execute mount -o remount,exec /media/Parallels\ Tools to allow it to be executed. In the browser that's open on the Parallels Tools disk, select File->Open in Terminal. Execute ./install --force-install to perform the upgrade. Reboot when it tells you to, and log back in as root. Eject the Parallel Tools disk image and set SELinux back to Enabled. Enjoy. David
