migration-framework

Allows for initiating start, stop, and migration of virtual machines by means of MQTT messages.

Requirements

• For migration-framework:
  • libvirt
• For fast-lib:
  • mosquitto
  • mosquittopp
  • yaml-cpp

Build instructions

mkdir build && cd build
cmake -DLibVirt_INCLUDE_DIR=<path/to/libvirt/include> -DLibVirt_LIBRARY=<path/to/libvirt.so> ..
make

Examples

• See directory "examples" for messages which can be parsed.

• To test messages:

  1. Start mosquitto daemon (and optional redirect output).

     • "-d" puts mosquitto in background after starting

     mosquitto -d 2> /dev/null

  2. Start migfra daemon:

     build/migfra

  3. Use mosquitto_pub to publish messages.

     • "-f <file>" the file that contains the message content.
     • "-q <2,1,0>" sets quality of service. For more information see mosquitto documentation.
     • "-t <topic>" the topic to publish on.

     mosquitto_pub -f examples/start_task.yaml -q 2 -t topic1  

  4. Use mosquitto_sub to see messages.

     • "-q <2,1,0>" sets quality of service. For more information see mosquitto documentation.
     • "-t <topic>" the topic to publish on.

     mosquitto_sub -q 2 -t topic1
