Instance Method Details

#clone(name) ⇒ Object

Fussion doesn’t have the concept of templates so one just clones regular VMs.

# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 27

def clone(name)
  requires :raw

  ::Fission::VM.clone(@raw[:fission].name,name)
  return connection.servers.get(name)
end

#destroy(options = { :force => false }) ⇒ Object

Destroy, deletes the VM from the local disk but only hard stops the VM before doing so if you set :force to true.

  if ready?
    if options[:force]
      stop
    end
  end

  @raw[:fission].delete
end

#haltObject

Halt and poweroff are just synonyms for stop.

# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 77

def halt
  stop
end

#ipaddressObject

We obtain the first ipaddress. This should generally be a safe assumption for Fusion. Even if an address is provided via NAT, bridge, or host only it will by accessible from the host machine the VM resides on.

152
153
# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 150

def ipaddress
  requires :raw
  ip(@raw[:fission])
end

#mac_addressesObject

Collecting all mac_addresses the VM has…mostly just because we are doing the same thing for the vSphere provider.

175

177
# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 174

#pathObject

Path to the VM’s vmx file on the local disk.

# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 141

def path
  requires :raw
  @raw[:fission].path
end

#power_stateObject

The power state of the VM is commonly going to be three values; running, not running, or suspended.

# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 130

165
166
# File 'lib/rackspace-fog/vmfusion/models/compute/server.rb', line 164

def private_ip_address
  ipaddress
end

#public_ip_addressObject

Keeping these three methods around for API compatibility reasons. Makes the vmfusion provider function similar to cloud providers and the vsphere provider. Future goal is to add an actual private and public concept. Needs changes to fission and a determination what is a public or private address here; bridge, nat, host-only.

    wait_for { ! ready? }
    start
    return true

    return false
  end

#resumeObject

Resuming from suspend is the same thing as start to Fusion.

#saveObject

Raises:

def save
  raise Fog::Errors::Error.new('Creating a new vm is not yet supported')
end

#scp(local_path, remote_path, upload_options = {}) ⇒ Object

  Fog::SCP.new(ipaddress, username, scp_options).upload(local_path, remote_path, upload_options)
end

#setup(credentials = {}) ⇒ Object

Sets up a new SSH key on the VM so one doesn’t need to use a password ever again.

    rescue Net::SSH::AuthenticationFailed, Timeout::Error
      retry
    end
  end
  Fog::SSH.new(ipaddress, username, credentials).run(commands)
end

#shutdownObject

This is a graceful shutdown but Fusion is only capable of a graceful shutdown if tools are installed. Fusion does the right thing though and if graceful can’t be initiated it just does a hard stop.

end

#start(options = { :headless => false }) ⇒ Object

Start is pretty self explanatory…if you pass :headless as true you won’t get a console on launch.
