Summary

You are using NTP server to synchronize the time. However, if you check the time on IMSVA and the NTP server, they are not the same.

IMSVA runs on Microsoft Hyper-V Server.

The issue happens when the Hyper-V application is unable to synchronize time with the VM image.

To resolve the issue:

  1. On the Hyper-V settings, go to the Management section.
  2. Go to Integration Service and untick Time synchronization.
  3. Click OK.
  4. Use SSH tool (such as Putty) to connect to IMSVA.
  5. Open ../boot/grub/grub.conf to edit the kernel boot options.
  6. Add the following after the appropriate kernel line:

    Note: The pider only allows values between 1 to 4.

    notsc pider=4

    Before the update, the kernel line is similar to the following:

    kernel /vmlinuz-2.6.18-128.1.OpenVA.2.0.1067 ro root=/dev/IMSVA/Root2 quiet

    After the update, it should be similar the following:

    kernel /vmlinuz-2.6.18-128.1.OpenVA.2.0.1067 ro root=/dev/IMSVA/Root2 quiet notsc pider=4

  7. Run the following commands to synchronize the time manually:

    $ service ntpd stop
    $ ntpd -q –g

  8. On another Secure Shell (SSH) session, set the hardware clock to the new time:

    $ hwclock –systohc

  9. Restart your machine.
