According to vmware kb article https://kb.vmware.com/kb/1019064 Determining why a virtual machine was powered off or restarted.
It means :
A Guest OS initiated halt generates this event within the virtual machine logs:
Mar 04 17:28:58.849: vcpu-0| PIIX4: PM Soft Off. Good-bye.
To continue troubleshooting, contact the operating system vendor to determine why the guest operating system initiated the halt. If the operating system vendor suspects that the outage was caused by VMware Tools or the virtual hardware, contact VMware support. If you determine that the operating system within your virtual machine reported a blue screen, kernel panic, or equivalent, see https://kb.vmware.com/kb/1003999
