This commit adds a unique error message for an empty box value. It
requires modifications to vagrantfile.rb because some Vagrantfile config
is used before validation occurs.
Allow Vagrantfile#machine_config to load properly when the requested
provider may not be currently available. Update the Environment to
utilize this when searching for plugin information to properly allow
box provided Vagrantfiles to define required plugins.
The project local metadata file may contain invalid information to properly
lookup the configured box. This may occur if the file has been moved,
modified, or the backing box has been removed. In those cases, fall back
to the configuration defined in the Vagrantfile to load the box.
When a guest is created, the box metadata information is stored in the
machine data directory. This allows modifications to happen to the
Vagrantfile definition of the box in use (box name change, box version
change, etc) while still allowing the Machine instance of an active
guest successfully load the box currently backing it.
This commit adds a bit more helpful messaging for the user when asking
for a provider that might not exist or does not follow the correct
casing. If it can find a match on a provider it knows about, it will
suggest it.
Prior to this commit if an override was given for a box version, it
would be ignored. This commit ensures that the box_version override is
used when specified in a Vagrantfile.
Added specs for the environment and vagrantfile. Added a methd to retrieve
autostart_machine_names. Changed the plugin up/command to use autostart_machine_names
when no argument was given to the command.
