I got the below error when working with a VM (Palo Alto OVA) in VMWare Workstation.

"The virtual machine's operating system has attempted to enable promiscuous mode on adapter 'adapter_name'. This is not allowed for security reasons."

Some googling brought me to the below article:

In short, on your host system and you are the only user on it, if you are using Linux as I have not tested this on Windows, open a terminal and run:

chmod a+rw /dev/vmnet0

If you need to lock this down more then follow the steps in the article to create a group with the correct access and add the users to the group.
