VMware Labs released a new Fling called Vmss2core Vmss2core. The download is available for Windows, Mac OS X and Linux and the total size is about 5MB.
Quote taken from the Fling page:
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.
Small note for Windows users
In addition, Windows hosts also need to have Visual C++ 2005 runtime installed.
