Overview

The base class for a guest. A guest represents an installed system within a machine that Vagrant manages. There are some portions of Vagrant which are OS-specific such as mountaing shared folders and halting the machine, and this abstraction allows the implementation for these to be seperate from the core of Vagrant.

Constructor Details

#initialize(vm) ⇒ Guest

Initializes the system. Any subclasses MUST make sure this method is called on the parent. Therefore, if a subclass overrides ‘initialize`, then you must call `super`.

end

#vm ⇒ Object (readonly)

Instance Method Details

#change_host_name(name) ⇒ Object

Called to change the hostname of the virtual machine.

Raises:

def change_host_name(name)
  raise BaseError, :_key => :unsupported_host_name
end

#configure_networks(networks) ⇒ Object

Configures the given list of networks on the virtual machine.

The networks parameter will be an array of hashes where the hashes represent the configuration of a network interface. The structure of the hash will be roughly the following:

:type      => :static,
:ip        => "192.168.33.10",
:netmask   => "255.255.255.0",
:interface => 1

Raises:

def configure_networks(networks)
  raise BaseError, :_key => :unsupported_configure_networks
end

#distro_dispatch ⇒ Object

This method is automatically called when the system is available (when Vagrant can successfully SSH into the machine) to give the system a chance to determine the distro and return a distro-specific system.

If this method returns nil, then this instance is assumed to be the most specific guest implementation.

def distro_dispatch
end

#halt ⇒ Object

Halt the machine. This method should gracefully shut down the operating system. This method will cause ‘vagrant halt` and associated commands to block, meaning that if the machine doesn’t halt in a reasonable amount of time, this method should just return.

If when this method returns, the machine’s state isn’t “powered_off,” Vagrant will proceed to forcefully shut the machine down.

Raises:

def halt
  raise BaseError, :_key => :unsupported_halt
end

#mount_nfs(ip, folders) ⇒ Object

Mounts a shared folder via NFS. This assumes that the exports via the host are already done.

Raises:

# File 'lib/vagrant/plugin/v2/guest.rb', line 64

def mount_nfs(ip, folders)
  raise BaseError, :_key => :unsupported_nfs
end

#mount_shared_folder(name, guestpath, options) ⇒ Object

Mounts a shared folder.

This method should create, mount, and properly set permissions on the shared folder. This method should also properly adhere to any configuration values such as ‘shared_folder_uid` on `config.vm`.

Parameters:

  • name (String) —

    The name of the shared folder.

  • guestpath (String) —

    The path on the machine which the user wants the folder mounted.

  • options (Hash) —

    Additional options for the shared folder which can be honored.

Raises:
