Testing the hyperv box hangs with username/password prompt for shared folder

[StefanScherer]

In my Jenkins build agent I also try to test the newly built vagrant box. In Azure I can create the boxes with the hyperv-iso builder. A vagrant up hangs with the following problem using the shared folder

The following WinRM command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

cmdkey /add:10.0.0.7 /user: /pass:

Stdout from the command:



CMDKEY: This command requires either the /U switch and 

        a username or else the /smartcard switch with a smartcard.

Ah, the Vagrant docs show some nice details https://www.vagrantup.com/docs/synced-folders/smb.html#options

smb_password and smb_username can be specified. This is ok for my Jenkins agents as Vagrant hosts.
