I booted DBVM from a USB drive, and everything worked normally until I opened a program that uses VT-d, after which the system froze. After enabling TSC protection, I encountered a CLOCK_WATCHDOUT_TIMEOUT blue screen error. I really can’t figure out why. Now I suspect that the IOMMU memory is not properly exposed to the system.

it's possible. There's only basic nested intel.vt support

what program do you use to i can reproduce ?

I found that after entering the system, loading DBVM using the driver works fine. However, if I boot into DBVM from a USB drive first and then enter the system, I suspect that some ACPI information is not accurately passed to the operating system, which may cause a blue screen.

your vmdisk.img is the same on the usb as the one the driver uses ? (In case you're on an older vmdisk.img)
