VBox status code: -2 (VERR_INVALID_PARAMETER). Result Code: NS_ERROR_FAILURE (0x80004005)[[BR]] Component: Console[[BR]] Interface: IConsole {d5a1cbda-f5d7-4824-9afe-d640c94c7dcf}[[BR]] ===================================================================[[BR]] Looking in the log, it appears the problem is when the geometry of the disk is read: 00:00:32.354 AHCI: LUN#0: disk, PCHS=1/16/63, total number of sectors 0 The number of cylinders in the above line is supposed to be 16383 in my case. The guest type does not matter. When I switch to the IDE controller, it works fine. If I'm using a vdi and SATA controller, it works fine, too. I'm using Logical Volumes as the ""raw"" disks so that might be a factor, but this setup was working fine in Virtualbox 1.6.6. I'm attaching the log, and vmdk file for one of the failing guests.
