I booted the system using DBVM from a USB drive but did not utilize any of its features. After launching the target game, I played normally for a period of time until its protection system triggered a CLOCK_WATCHDOG_TIMEOUT blue screen. In the call stack, I found that the thread causing the exception was querying information about a certain process and then timed out while waiting. When I switched to the CPU core that timed out in the full core dump, I discovered that the call stack of that thread was completely missing, and the CET bit in the CR4 register was lost. The known information is as follows:

1.DBVM was booted from a USB drive, but none of its functions were used.
2.The target program has VT-d protection enabled.
3.The operating system is Windows 10 with the latest updates.
4.The CPU is an Intel Core i7 14th Gen (CET is enabled by default in the OS).
5.When using Windows' native VT, the program runs without any issues.

What additional information should I investigate to analyze this issue? The full dump is 31 GB, and I can provide necessary details as required.

clock_watchdog_timeout just means DBVM didn't know how to handle something which results in a frozen CPU that doesn't respond to anything anymore. (Which includes full system crash causing an instant reboot)

If you have a POST display on the mainboard or pci-e add-on card the value on the display could give a clue on why dbvm failed

The memory dump isn't that useful as I don't have the debug symbols of that version (and would only work if dbvm physical memory cloak was off)

Try dbvm 19: https://cheatengine.org/download/dbvm19.zip
