My virtual box xml files became corrupted when my computer ran out of space (both the .vbox and .vbox-prev). However, the .vdi files and snapshots are fine. Whenever I try to use VBoxManage it keeps complaining about the xml files being messed up. Is there another program that can re-assemble the snapshots into the base vdi file?
