This happened on FreeBSD with VirtualBox 3.1.4 and i could also reproduce that on Linux with VirtualBox 3.1.4. Try these commands to reproduce the bug: {{{ $ VBoxHeadless -s Test & $ VBoxManage controlvm Test savestate Sun VirtualBox Command Line Management Interface Version 3.1.4_OSE (C) 2005-2010 Sun Microsystems, Inc. All rights reserved. 0%...10%...20%... Error: failed to save machine state. No error message available! }}} The reason is an arithmetic exception (division by zero) in the displayMakeThumbnail (src/VBox/Main/DisplayImpl.cpp, line 161) due to cx and cy are set to 0. cxThumbnail = (kMaxSizeThumbnail * cx) / cy; One possible solution would be to not generate the thumbnail. Patches for this are attached.",defect,closed,VM control,VirtualBox 3.1.4,fixed,vboxheadless savestate,,other,Linux
