Allow to use a TAP interface multiple time

[grossmj]

You get the following message if you attach to a TAP more than once:

unable to create NIO TAP for bridge 'cfc22796-ad24-4101-ab1e-eedffdf623c5-0': create_nio_tap: unable to open TAP device tap0 (Device or resource busy)

[grossmj]

I don't think this is possible

@grossmj do you have any further information regarding this? I've run into the issue on a GNS3VM with multiple users who would like access to external resource from their projects, but once a user has connected to a tap interface no-one else can use it

You need to create a bridge and user will create different tap to connect to it.

Ah, so I've gone one step too far in creating a static tap interface. Thanks for the quick response!

GNS3 on Linux should create the tap interface for you if you use a bridge in a cloud node and we correctly detect it.

That's good to know. Just tested it, looks very good. I've updated http://www.bernhard-ehlers.de/blog/2017/07/11/gns3-cloud-linux.html

How we detect bridge: https://github.com/GNS3/gns3-server/blob/40cc5d76b33e457022f2fb2703ca9ba4e52bfa85/gns3server/utils/interfaces.py#L172
