Stuck at "Waiting for the machine to report its IP address..."

[tbarbette]

Hi! Thanks for your tutorial !

No matter the switch I use I get the following :

==> default: Starting the machine...
==> default: Waiting for the machine to report its IP address...
    default: Timeout: 120 seconds
Hyper-V failed to determine your machine's IP address within the
configured timeout. Please verify the machine properly booted and
the network works. To do this, open the Hyper-V manager, find your
virtual machine, and connect to it.

The most common cause for this error is that the running virtual
machine doesn't have the latest Hyper-V integration drivers. Please
research for your operating system how to install these in order
for the VM to properly communicate its IP address to Hyper-V.

Which image (if possible ubuntu) did you use? I tried to force a private network with an IP set in the vagrant file, but the machine does not get automatically that IP so it does not work either...
