Overview

Instance Attribute Summary (collapse)

• - (Object) pnode

  The physical node to work on.

• - (Object) vplatform readonly

  The virtual platform that describes all virtual resources set on this physical node.

Instance Method Summary (collapse)

• - (Object) destroy(resource)

  Remove a virtual resource (use it's _remove associated method) ==== Attributes * resouce The Resource object (have to be of class VNode, VNetwork or VRoute).

• - (Object) get_container(name)

  Gets the Container object associated to a virtual node ==== Attributes * name The name of the virtual node (String) ==== Returns Container object or nil if not found.

• - (Object) get_vnode(name)

  Gets a virtual node object specifying it's name ==== Attributes * name The name (String) ==== Returns VNode object or nil if not found.

• - (ConfigManager) initialize constructor

  Create a new ConfigManager object.

• - (Object) set_global_arptable(vnode, data, file)
• - (Object) set_global_etchosts(vnode, data)
• - (Object) vnetwork_add(vnetwork)

  Add a virtual network ==== Attributes * vnetwork The VNetwork object.

• - (Object) vnetwork_remove(vnetwork)

  Remove a virtual network ==== Attributes * vnetwork The VNetwork object.

• - (Object) vnode_add(vnode)

  Add a virtual node and initialize all the resources it will use on the physical node (uncompress it's filesystem, create it's container (cgroups,lxc, …), …) ==== Attributes * vnode The VNode object.

• - (Object) vnode_freeze(vnode)
• - (Object) vnode_reconfigure(vnode)

  Reconfigure a virtual node (apply changes to the abstract virtual resources to the physical node settings) ==== Attributes * vnode The VNode object.

• - (Object) vnode_remove(vnode)

  Remove a virtual node and clean all it's associated resources on the physical node (remove it's filesystem files, remove it's container (cgroups,lxc, …), …) ==== Attributes * vnode The VNode object.

• - (Object) vnode_start(vnode, distempnode)

  Start a virtual node to be able to use it (it have to be installed and in the status READY) ==== Attributes * vnode The VNode object * distempnode DistemPnode object.

• - (Object) vnode_stop(vnode)

  Stop a virtual node (it have to be started and in the status RUNNING) ==== Attributes * vnode The VNode object.

• - (Object) vnode_unfreeze(vnode)
