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

Requirements

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

Considerations

 * 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 ...
