control_network

This MC creates a control network within the FIREWHEEL experiment. Essentially, it connects all VMs in the experiment to a single network with the 172.16.0.0/16 IP space and adds the Control Node to this network with an IP address of 172.16.255.254/16. Using this MC, users can take advantage of the ssh and scp helpers.

Plugin

class control_network_plugin.InsertControlNetwork(graph, log)[source]

Bases: AbstractPlugin

Create a “Control” network which provides access to all VMs within an experiment.

This standard network uses the 172.16.0.0/16 IP space. Therefore, if you use this MC, your experiment should NOT use this IP space for standard communication.

Note

This potentially provides access for VMs to communicate with your physical compute nodes. The Control Node will have the IP address 172.16.255.254.

__annotations__ = {}

_get_next_ip()[source]

Get the next IP address in the control subnet.

Returns:: The next valid IP address.
Return type:: netaddr.IPAddress

run()[source]: Add a control network switch and connect every VMEndpoint to that switch.
