When using the salt provisioner with verbose=true, most lines read with an extra newline:
```
[INFO ] Syncing modules for environment 'base'
[INFO ] Loading cache from salt://_modules, for base)
```
because the line read has a newline, and emitting the log entry again includes an additional newline.
fixes#3083
Detect the presence of the default DHCP server that comes in a fresh
VirtualBox install and clean it up to prevent it from colliding with
Vagrant-managed network config.
In order to accomplish this, we:
- add a `remove_dhcp_server` call to the virtualbox driver
- fix dhcp options parsing to allow `:dhcp_{ip,lower,upper}`
configuration options to make it through (so a user can override the
removal behavior with some explicit configuration)
- add the full `:network_name` to the details returned from
`:read_dhcp_servers`, so we can have a durable value to pass to
`:remove_dhcp_server`
Note that we do have to eat one more `VBoxManage list dhcpservers` for
each network interface to support this, but this seemed like a nominal
cost
This is just a refactor, no behavior change.
Instead of stitching together dhcpserver info in the structure returned
from `read_host_only_interfaces`, sprout a new driver method called
`read_dhcp_servers` to return that information separately.
This means that driver clients (well there's really only _one_ client in
`ProviderVirtualBox::Action::Network`) have to do a bit more work to get
interface and DHCP server information.
But this gives us (a) a cleaner and more consistent driver interface and
(b) groundwork for a fix for #3083, which will require interacting with
DHCP servers outside of the context of host-only interfaces.
Like Vagrant's default SSH behaviors (e.g ssh or ssh-config commands),
the Ansible provisioner should by default not modify or read the user
known host file (e.g. ~/.ssh/known_hosts).
Given that `UserKnownHostsFile=/dev/null` SSH option is usually combined
with `StrictHostKeyChecking=no`, it seems quite reasonable to bind the
activation/disactivation of both options to `host_key_checking`
provisioner attribute.
For the records, a discussion held in Ansible-Development mailing list
clearly confirmed that there is no short-term plan to adapt Ansible to
offer an extra option or change the behavior of
ANSIBLE_HOST_KEY_CHECKING. For this reason, the current implementation
seems reasonable and should be stable on the long run.

- force `--connection=ssh` (any other modes like paramiko or smart are not
supported)
- give the highest priority to `raw_arguments` for sake of simplicity (in
usage, in code and in documentation)
- fix position of the `--limit` argument (the generated inventory could be
shadowed by `raw_arguments`, while ansible.limit was able to override
`raw_arguments`
ref #3396
When `--connection` argument is not specified, Ansible will use the
'smart' mode, which can either use `ssh` or `paramiko` transports,
depending of the version of OpenSSH available. If OpenSSH version is new
enough to support ControlPersist technology, `ssh` will be used.
See also http://docs.ansible.com/intro_configuration.html#transport.
In order to support some advanced features of Vagrant (e.g. multiple ssh
private key identities or ssh forwarding), the Ansible provisioner
already must force `ssh` connection mode.
Having to deal with the possible fallback to `paramiko` increase the
burden of special cases that Ansible provisioner must handle, without
any added value, as Vagrant is based on OpenSSH and its users are
usually using modern operating systems.
With this change, the Ansible provisioner will officially only support
`ssh`. It will still be possible to switch to another connection mode
via `raw_arguments`, but it will breach the "contract", and no
(community) support can be expected in such use case.

This separates the truly basic pieces of Chef (like install url and
log_level) from the runner pieces of Chef (like provisioning_path). This
is necessary because the Chef Apply provisioner does not actually need
most of the Chef configuration options.
Eliminate warnings like this:
vagrant/plugins/hosts/linux/cap/nfs.rb:74: warning: character class has '-' without escape: /^# VAGRANT-BEGIN:( 1000)? ([\.\/A-Za-z0-9-_]+?)$/
As a result of #4670 and the safe decision to not memoize
machine.ssh_info (see 89a4a29d65 and
5036d16461), it is preferable to store the
ssh_info hashes and avoid multiple function calls when generating the
ansible inventory.
In the situation where the SSH key has invalid permissions/owner, the reconnect-loop keeps failing repeatedly yet stays silent about the reasons. A message must be reported from the default exception handler (added). In addition, the situations where the SSH key owner or permissions are wrong must lead to a proper failure (added). Ideally, though, the owner/permissions check must happen before launching the VM, hence this is not a perfect fix.
For FreeBSD guests, Virtualbox can sometimes report the private network
interface IP address as "0.0.0.0". This will cause an invalid NFS
exports file to be generated for FreeBSD and OS X hosts.
Fixed by not allowing Virtualbox to report a guest IP address of
"0.0.0.0".
