Also to add, you can run the below command from SSH of the host for this VM
# watch -d 'ls -luth | grep -E "delta|flat|sesparse"'
Run this command once the directory is changed to the virtual machine folder. This command is used to monitor the snapshot consolidation process. The timer that updates itself periodically is a result of this command, and it indicates that the changes are written to the base disk.
