Synchronize VM time with Hyper-V or Linux KVM host time

For a gateway deployed on VMware ESXi, setting the hypervisor host time and synchronizing the virtual machine time to the host is sufficient to avoid time drift. For more information, see Synchronize VM time with VMware host time. For a gateway deployed on Microsoft Hyper-V or Linux KVM, we recommend that you periodically check the virtual machine time using the procedure described following.

To view and synchronize the time of a hypervisor gateway virtual machine to a Network Time Protocol (NTP) server

1. Log in to your gateway's local console:

   • For more information on logging in to the Microsoft Hyper-V local console, see Access the Gateway Local Console with Microsoft Hyper-V.

   • For more information on logging in to the local console for Linux Kernel-based Virtual Machine (KVM), see Accessing the Gateway Local Console with Linux KVM.

2. On the Storage Gateway Configuration main menu screen, enter the corresponding numeral to select System Time Management.

3. On the System Time Management menu screen, enter the corresponding numeral to select View and Synchronize System Time.

   The gateway local console displays the current system time and compares it with the time reported by the NTP server, then reports the exact discrepancy between the two times in seconds.

4. If the time discrepancy is greater than 60 seconds, enter y to synchronize the system time with NTP time. Otherwise, enter n.

   Time synchronization might take a few moments.
