Use the vmss2core tool to create a memory dump from the virtual machine snapshot

Prerequisites:

- Obtain vmss2core

- Please refer https://kb.vmware.com/s/article/2003941

- Retrieve files vmss2core.exe and zlib1.dll from VMware workstation installation folder

C:\Program Files (x86)\VMware\VMware Workstation or C:\Program Files\VMware\VMware Workstation\

Note: If vmss2core is not available in these install directories, it can be downloaded. Download location is available in https://kb.vmware.com/s/article/2003941

Steps:

- Place the vmss2core tool and the VMware snapshot file into the same folder

- Run the vmss2core (vmss2core-sb-8456865.exe in this example) in the command line with the following parameters:

Specify the guest operating system from which the snapshot was created:

* W8 - Windows 8 and later or Windows Server 2012 and later.

* W - Windows 7 and older or Windows Server 2008 and older.

- Virtual machine snapshot filename (for example, virtual_machine_name.vmsn)

Note: Use quotes if the filename contains blank spaces. "virtual machine name.vmss"

Sample Command: vmss2core-sb-8456865.exe -W8 "virtual_machine_name.vmss virtual_machine_name.vmem"

Note: When the vmss2core tool completes the operation, it creates a memory dump file named memory.dmp that can be used for additional troubleshooting ( Please share this to MS Support )
