#820 Avp suggest Hardware Virtualization is not available after first reboot of my OS

  • Fixed

    , last edited by Jarvis

    Reproduction steps:

    install product, update it

    reboot OS

    Actual result:

    Before the first reboot, everything work fine.

    after reboot, avp told me there is no hardware support of virtualization technology, and I should change a device which support hardware virtualization.

    Expected Result:

    hardware virtualization based protection should work fine, there should not be any alert about it.

  • @xzz123 , Thank you!

  • Just installed latest beta build and also the databases is the latest( although it was released two days ago)

    The problem is no longer reproduced.

  • @dmitriy-pisarets

    Glad to hear that.

    Will proceed test ASAP.

  • @xzz123, we hope tomorrow will be new build

  • @dmitriy-pisarets


    Sadly, I can not test current beta build due to continuous crash

    I even do not have a chance to start the product successfully.

    Do you need me check the problem using previous build? Is it ok to wait for another build?

  • @xzz123, hello sir!

    Does it reproduce now? Developers say, new updates should fix problem,  

  • @xzz123 thank you. 

  • @dmitriy-pisarets


    Here are traces and GSI6 report.

    I turn on traces and try restart product and restart OS, than turn off traces.

    Product language is simplified chinese, the notification told me that my OS is found to be unstable when virtualization is enabled, so it is not available.

  • @xzz123, can you send traces and screenshot? 

    Traces: It will be enough to  start recording, restart product, open main menu, go to notifications.  

  • @xzz123 Hello! Sorry, it took some time to get here =). I'll grab it.

  • Hello

    can anyone take a look?

    What should I do so that dev will reconsider about this case?

  • @dmitriy-pisarets


    The problem came back.

    I have been using latest beta build for days, it is OK for these days.

    I can install the product with secure boot enabled, and hardware-virtualization is enabled without problem

    BUT, after a recent databases update, I found again the product alert me that vt is not available, because my OS is found not stable if vt is turn on.

    I never changed my device these, so that is wired........

    My Device now: Thinkpad X240s with secure boot enabled and boot mode is UEFI only & CSM off.

  • Cannot Reproduce
  • @xzz123

    i see, Thank you for information. So we will close this issue till new reproduction will appear. 

  • @dmitriy-pisarets

    Not reproduced.

    But the situation has changed.

    Quite a long time ago, I report this problem: https://bug.kaspersky.com/issues/5846

    at that time, there was no problem with hardware Virtualiation.

    On about 2~3 previous beta build, I somehow able to install product with secure boot enabled, And here came the hardware-virtualization problem.

    This cuurent build .5.852, I again not able to install the problem with secure boot ebabled. And the hardware-virtualization problem disappear.

    I do not know the relationship between two problem. But since the environment has changed, I do not have a clear answer for your question.

  • @xzz123, hello sir!

    can you reproduce it on new version?

    I found that may be the bug in some AV modules that caused the problem

    I reinstalled the product, than reboot without any update. there is no alert about virtualization

    Than I ran a databases update and reboot OS, after the reboot, alert about vt is not available appear.

    I collected the entire traces begin from the product install till problem appear.

    1 install product

    2 reboot

    3 update product

    4 reboot

    5 problem reproduced.
