minimega.resolve_vm_images

This MC ensures that all VMs have an image available. That is, if any VMs have not had an image assigned explicitly, this MC will assign a default image. Additionally, it will decorate all VMs with minimega.emulated_entities.MinimegaEmulatedVM.

The default image types are:

• If the VM type is host is: Ubuntu1604Server.

• If the VM type is router is: Helium118.

• If the VM type is switch is: Ubuntu1604Server.

Note

Most Switches are not decorated with VMEndpoint and are not launched as a VM.

Attribute Provides:

• vm_image_details

Attribute Depends:

• topology

Model Component Dependencies:

• linux.ubuntu1604

• vyos.helium118

• minimega.emulated_entities

Plugin

class minimega.resolve_vm_images_plugin.ResolveVMImages(graph, log)

Bases: AbstractPlugin

Assign a default image to all VMEndpoints.

__annotate_func__ = None

__annotations_cache__ = {}

__firstlineno__ = 10

__static_attributes__ = ('image_store',)

_assign_default_images()

For every VMEndpoint in the experiment graph, assign an image if one hasn’t been assigned already. If a type is not specified for an endpoint, use "host". Default images are specified based on the type property.

default_images = {'host': <class 'linux.ubuntu1604.Ubuntu1604Server'>, 'router': <class 'vyos.helium118.Helium118'>, 'switch': <class 'linux.ubuntu1604.Ubuntu1604Server'>}

run()

Create the ImageStore and call _assign_default_images() which performs the main plugin logic.
