From Fedora Project Wiki
Below you can see a list of issues that are known to us when building appliances using BoxGrinder Build for selected operating system.
Fedora 15[edit]
Appliances built with Fedora 15 selected as the guest OS may not work correctly:
- Network device rename issue: BGBUILD-204
- Root partition mounts. The appliance will boot correctly, but if you run df -h you'll see only a tmpfs mounted of size 500 MB, although you'll see all filesystems on root partition... BGBUILD-209
- Cannot login to TTY1. If you boot your appliance you must select another terminal (ALT+F2 for example) to be able to log in.
