Hi,
I had the same problem once. I have a solution for you.
you have to open .vmx file. For that, you normally need a text editor. I hope you are familiar with the editor. From your VM you can get the .vmx file. Open it and edit it with this: #log.fileName = “/vmfs/volumes/4b8bd18f-c1f89b5a-1914-002219c8e7a3/vmware.log”
You have to use this line in the comment. Now reboot the virtual machine and let it take effect. Then you can power it off normally.
