Vmss2core is a tool to convert VMware checkpoint state files into formats that third party debugger tools understand. It can handle both suspend (.vmss) and snapshot (.vmsn) checkpoint state files (hereafter referred to as a ‘vmss file’) as well as both monolithic and non-monolithic (separate .vmem file) encapsulation of checkpoint state data.
The vmss2core tool can produce core dump files for the Windows debugger (WinDbg), Red Hat crash compatible core files, a physical memory view suitable for the Gnu debugger gdb, Solaris MDB (XXX), and Mac OS X formats. Debugging Virtual Machines with the Checkpoint to Core Tool provides the usage information for the vmss2core tool.
Note: This last update has improved support for Win 8.1/Win2012 R2 vmss files.
In addition, Windows hosts also need to have Visual Studio 2008 Service Pack 1 runtime installed. Please see http://www.microsoft.com/en-us/download/details.aspx?id=26368 for instructions on getting the runtime.
