# sk105862 - In a Hyper-V environment, the Virtual Machine's clock moves faster than the hardware time

| Property | Value |

| Solution ID | sk105862 |
| Date Created | 2015-05-04 |
| Last Modified | 2020-10-15 |
| Technical Level | General |
| Products | Security Gateway, Security Management Server, Multi-Domain Security Management Server |
| Versions | R82.10, R82, R81.20, R82.20 |
| OS | Gaia |

## Symptoms

- In a Hyper-V environment, the Virtual Machine's clock (OS time) moves faster than the hardware (Host) time (2-3 seconds every minute).  
As a result, the Virtual Machine's clock drift can accumulate rapidly and prevent NTP from working correctly.

## Cause

Hyper-V clocksource does not work on 64-bit kernel.

## Solution

This problem was fixed. The fix is included in:

* For Security Management Server:

  * [Check Point R80.40](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk160736)
  * [Check Point R80.30](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk144293)
  * [R80.20 Management Feature Release](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk123473)
* For Security Gateway:

  * [Check Point R80.40](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk160736)
  * [Check Point R80.30 with Gaia 3.10](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk152652)

Check Point recommends to always upgrade to the most recent version   
([upgrade Security Gateway](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=overview&product=435) / [upgrade Security Management Server](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=overview&product=184) / [upgrade Multi-Domain Security Management](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doShowproductpage&productTab=overview&product=166)).

For **other [supported](http://www.checkpoint.com/support-services/support-life-cycle-policy/index.html) versions** , Check Point can supply a **Hotfix** . [Contact Check Point Support](https://www.checkpoint.com/support-services/contact-support/) to get a Hotfix for this issue.  
A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.  
For faster resolution and verification, please collect [CPinfo files](http://supportcontent.checkpoint.com/solutions?id=sk92739) from the Security Management Server and Security Gateways involved in the case.

Follow these steps:

1. Hyper-V integration services should not offer time sync.  
   Uncheck this setting in the "Advanced" section of hardware properties of the Hyper-V VM.  
   If this is not acceptable, then proceed to the next step.

2. [Contact Check Point Support](http://www.checkpoint.com/support-services/contact-support/index.html) to get a Hotfix for this issue (Issue ID 02550557).  
   A Support Engineer will make sure the Hotfix is compatible with your environment before providing the Hotfix.  
   For faster resolution and verification, please collect [CPInfo file](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92739) from Gaia OS running within Hyper-V that is involved in the case.

   **Hotfix installation instructions:**
   1. Hotfix has to be installed on ***Gaia OS running within Hyper-V***.

      **Notes:**
      * In cluster environment, this procedure must be performed on *all* members of the cluster.
      * In Management HA environment, this procedure must be performed on *both* Management Servers.
   2. Procedure:

      * Using CPUSE - On Security Gateway / Management Server running Gaia OS R75.40 and above:

        Make sure to install the [latest build of the CPUSE Agent](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#Latest build of CPUSE and What's New).

        Refer to [sk92449: CPUSE - Gaia Software Updates (including Gaia Software Updates Agent)](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#How to work with CPUSE):
        * Section "[(4-A-c)](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#How to work with CPUSE - How to download and import a CPUSE package - Import instructions for Offline procedure - Gaia Portal)" / "[(4-A-d)](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#How to work with CPUSE - How to download and import a CPUSE package - Import instructions for Offline procedure - Gaia Clish)" - refer to import instructions for *Offline procedure*
        * Section "[(4-B-a)](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#How to work with CPUSE - How to install a CPUSE package - Installing a Hotfix package / Minor Version package)" - refer to installation instructions for *Hotfixes*

        You can also use the [sk111158 - Central Deployment Tool (CDT)](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk111158) to install this hotfix on Security Gateways.

        **Note:** Reboot is required.
      * Using Legacy CLI - On VSX Gateway running Gaia OS R75.40VS - R77.30:

        Note: You must be connected either over Console, or LOM card (SSH session could be disconnected). On VSX versions R75.40VS - R77.30, the Gaia CPUSE does not support installation of hotfixes (refer to [sk92449](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk92449#System requirements and limitations) - section "(2)" - "VSX Gateways").
        1. Transfer the hotfix package to the machine (into some directory, e.g., */some_path_to_fix/*).

        2. Unpack and install the hotfix package:

           ***\[Expert@HostName:0\]# cd /some_path_to_fix/***   
           ***\[Expert@HostName:0\]# tar -zxvf SecurePlatform_\<HOTFIX_NAME\>.tgz***   
           ***\[Expert@HostName:0\]# ./SecurePlatform_\<HOTFIX_NAME\>***
           **Note:** The script will stop all of Check Point services (*cpstop*) - read the output on the screen.
        3. Reboot the machine.
