I've opened CPU virtualization in BIOS, but still show this error: https://github.com/jt0129/Test/blob/master/Screenshot%20from%202023-09-28%2012-15-49.png?raw=true

Please check if opened vt-d correctly in bios.

Hi, I got the same error. So basically I am trying to run HyperEnclave in Virtualbox with nested VT-x enabled. I checked that the vt-d is enabled in my host machine. I wonder if it is possible to run HyperEnclave in virtualbox or it's necessary to run it on a physical machine. Thanks.

Hi @Tim-C1 , thanks for your for your interest for HyperEnclave!

Currently, HyperEnclave does not support running in a virtualized environment, we can only run HyperEnclave on a physical machine.

Thank you so much for your timely reply!
