Virtual Machine reboots at the same time each day

Products

• VMware vCenter Server 8.0

Issue/Introduction

• A virtual machine reboots at a specific time every day.
  
  
• The following snippets are found in the vCenter logs in /var/log/vmware/vpxd/vpxd.log:

YYYY-MM-DDTHH:MM:YY.471Z info vpxd[1807294] [Originator@6876 sub=vpxLro opID=ProcessScheduledTaskFiring-4ac82af1] [VpxLRO] -- BEGIN task-2027 -- vm-####-- vim.VirtualMachine.rebootGuest -- 

Environment

VMware vCenter 8.x

VMware vCenter 7.x

Cause

A "Restart Guest OS" scheduled task is configured on the vCenter that triggers the reboot of the virtual machine.

Resolution

Investigate whether a scheduled task exists at the following location and make the necessary changes if required. 

• Select the Virtual Machine from the vCenter inventory.
• Navigate to the Configure tab.
• Select Scheduled Tasks.
• There should be a scheduled task present. Select edit option in the task to view its target and configuration details.
• If a scheduled task exists, determine whether it was created for a specific purpose. If not, the task can be removed.

This should prevent the Virtual Machine from rebooting as a result of the scheduled task.
