rsync problem without too many info

[gianarb]

Hello

I have this problem, still not sure if it's something related this plugin or not but with digitalocean the same vagrantfile is working fine. I have a problem when chef provision uses rsync to share folders:

==> b1: Rsyncing folder: /home/gianarb/.berkshelf/vagrant-berkshelf/shelves/berkshelf20170308-19701-oud8yl-b1/ => /tmp/vagrant-chef/f278b110c9255cbe6230ed1696cc3e58/cookbooks
==> b1: Rsyncing folder: /home/gianarb/git/influxdata-autoscaler/cookbooks/ => /tmp/vagrant-chef/4f0231c9be8e43bff7a62ee010b9a3e3/cookbooks
==> b1: Rsyncing folder: /home/gianarb/git/influxdata-autoscaler/roles/ => /tmp/vagrant-chef/86d22483ef2ea7c421791b5d73b1f927/roles
==> b1: Rsyncing folder: /home/gianarb/git/influxdata-autoscaler/nodes/ => /tmp/vagrant-chef/14bc133efaf68bdb7398bfcb994e9b20/nodes
An unknown error happened in Vagrant OpenStack provider

To easily debug what happened, we recommend to set the environment
variable VAGRANT_OPENSTACK_LOG to debug

    $ export VAGRANT_OPENSTACK_LOG=debug

If doing this does not help fixing your issue, there may be a bug
in the provider. Please submit an issue on Github at

with the stracktrace and the logs.

We are looking for feedback, so feel free to ask questions or

Catched Error: No host IP was given to the Vagrant core NFS helper. This is
an internal error that should be reported as a bug.

VAGRANT_OPENSTACK_LOG is already set but I can not find nothing useful. Somebody else has the same issue?
It always fails in at the same point
Thanks
