The issue is that

/opt

needs to be owned by

root

because the

vde_vmnet

code will be run as root, so the code must not be modifiable by a non-root user. You could try

sudo chmod root:wheel /opt

to change it, and then verify with:

$ ls -ld /opt
drwxr-xr-x  8 root  wheel  256 10 Dec 23:26 /opt
