How to generate a full memory DUMP of a VM

Windows DUMP file provides information about the cause of the system crash. But generating a DUMP file on the ESXi system is a bit different. So, will look at the steps. We have divided the process into 2 main steps.

Step 01 – Create and download a VM snapshot

  • In the VMware environment, select the virtual machine that has issues.
  • Replicate the issue on the virtual machine.
  • Right-click the virtual machine and click Snapshots → Take snapshot.

  • Type the name, select the check box next to Snapshot the Virtual Machine’s memory and click OK.

  • Select the virtual machine and click Datastores and click the datastore name.
  • Select the virtual machine, select the .vmsn file (VMware Snapshot file), click Download and save the file locally.

Step 02 – Use the vmss2core tool to create a memory dump from the virtual machine snapshot

  • Download Vmss2core.
  • Select the check box next to I have read and agree to the Technical Preview License I also understand that Flings are experimental and should not be run on production systems. Select the file for your operating system from the drop-down menu (for example, if you want to run the tool on Windows, select vmss2core-sb-8456865.exe) and click Download.
  • Place the vmss2core tool and the VMware snapshot file into the same folder.
  • Run the vmss2core (vmss2core-sb-8456865.exe) in the command line with the following parameters.
  • Specify the guest operating system from which the snapshot was created.

Use quotes if the filename contains blank spaces.

vmss2core-sb-8456865.exe -W8 “virtual_machine_name.vmsn”

  • -W8 —Windows 8 and later or Windows Server 2012 and later.
  • -W —Windows 7 and older or Windows Server 2008 and older.

Finally, you may use the WinDbg tool to analyze the generated Windows DUMP file.
