Host Agent

Live Notes may be taken for this topic at: http://etherpad.openstack.org/HostAgent


  • should be a nice unix daemon
  • should support syslog
  • failure should not affect guest instances


  • Heavy I/O operations should be executed with Processing Pools (or some mechanism that limits concurrent operations)
  • Upgrades to HostAgent code (apt-get update) without breaking current long running tasks (spawning of instances)
  • HostAgent should be stateless, with persistent state in the datastore
  • Support GuestAgent ...
