Window 7 as guest. I can't access the host optical drive from the guest OS. I was able to install it by dd'ing the install DVD to the harddrive, and VBox used that beautifully. It all works quite well, but whenever I try to use the actual optical drive, I get a 'permissions error': "Unable to mount the CD/DVD Host Drive HL-DT-STDVDRAM GH24LS50 DVDRAM GH24LS50 (cd0) on the machjine Windows_7_64bit. Would you like to force mounting of this medium?" "Could not mount the media/drive '/dev/cd0'" And the Details: "Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Callee: IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}" Incidentally, inspite of the message, there is no "force mount" option given, only 'cancel' and 'force unmount'. I've followed the handbook and Wiki for the DVD/CD access, I'm in the operator group, atapicam is loaded, hald is enabled and running and the permissions for cd0, xpt0 and pass0 are all 0660. I've also tried adding CD0 in the graphical interface before I start the VM. Bizarrely, this caused VBox to try to boot from the DVD (even though that is unchecked in the boot options). The only other thing I've tried is to disable the automounting of media with Gnome, in case that was interfering. No luck. So, anyone have any ideas? They would be most appreciated. Thanks for your time, Scott -- sdb@ssr.com
