Avp suggest Hardware Virtualization is not available after first reboot of my OS
-
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.

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.

Hello
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.
OS: Windows10 14393.2670 LTSB x64

@xzz123, can you send traces and screenshot?
Traces: It will be enough to start recording, restart product, open main menu, go to notifications.

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.

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.

Hello
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?
