The nova.api.openstack.compute.legacy_v2.contrib.agents Module

class AgentController

Bases: object

The agent is talking about guest agent.The host can use this for things like accessing files on the disk, configuring networking, or running other applications/scripts in the guest while it is running. Typically this uses some hypervisor-specific transport to avoid being dependent on a working network configuration. Xen, VMware, and VirtualBox have guest agents,although the Xen driver is the only one with an implementation for managing them in openstack. KVM doesn’t really have a concept of a guest agent (although one could be written).

You can find the design of agent update in this link: http://wiki.openstack.org/AgentUpdate and find the code in nova.virt.xenapi.vmops.VMOps._boot_new_instance. In this design We need update agent in guest from host, so we need some interfaces to update the agent info in host.
