Locating a Dump File in a Virtual Machine

Locate a dump file in a virtual machine (VM) if the VM has crashed and you need to collect the dump file for troubleshooting purposes.

To collect a dump file for your service representative

• For Windows-based VMs—Retrieve the file from C:\WINDOWS\MEMORY.DMP (by default) in the file system of the VM.
• For Linux-based VMs—Retrieve the dump file from the /var/crash directory (by default) in the file system of the VM.

If you cannot locate a dump file, ensure that you configured the guest operating system to generate a crash dump file when the operating system hangs:

• Windows-based VMs: Follow the instructions in the Microsoft article, How to generate a complete crash dump file or a kernel crash dump file by using an NMI on a Windows-based system (Article ID: 927069). Follow the instructions in the More Information section.
• Linux-based VMs: Install the kexec-tools package and enable crash dumps. For more information, see your Linux documentation.
