How to capture a memory dump from a VMware virtual machine without stopping its execution. This is useful in cases where customers do not want to force a crash or change Windows dump parameters and reboot the machine. This procedure can be done without interrupting the execution of the machine.
How to capture a memory dump from a VMware virtual machine
vmss2core.exe -W snapshot.vmsn snapshot.vmem
If the snapshot file is from a Windows 8/Server 2012 or later VM, the command line is
vmss2core.exe -W8 snapshot.vmsn snapshot.vmem
(Note: vmsn may be vmss, and the vmem file may not be present or necessary.)
Successful output should be a "memory.dmp" file suitable for use with WinDbg
