This should fix the cleaning up of the default VirtualBox dhcpserver,
which we've been fighting with for ages over in #3083. We were checking
for a structure _including_ a netmask, but the driver was not populating
netmask.
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.
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".
The original fix for the "missing interpolation argument :stderr" bug
was in d4b3f226, but it only addressed the driver for VirtualBox 4.3:
https://github.com/mitchellh/vagrant/issues/3277
This backports the fix to the drivers for VirtualBox 4.0, 4.1, and 4.2.
