That's because you should run this command on your virtualenv previously created, are you doing it like that?

@netpanda Could you let me know what tutorial you are using to deploy Cuckoo with Ubuntu 21.10 and Python 3.9 + Windows 10 as a guest?

Thank you.

I'm using these ones...
Cuckoo tutorial part 1
Cuckoo tutorial part 2
It is on Ubuntu, but I think it's the same idea...

Also just ran into this issue. Were any solutions ever found?
Thanks!

EDIT: I think I screwed up the part about changing chmod u+s /usr/lib/qemu/qemu-bridge-helper. It appears to be working now for me.
