com.cloud.network.guru.NetworkGuru
- Designs a virtual network depending on the network offering. - Implements the virtual network when a virtual machine requires the network to be started. There can be multiple NetworkGurus in a CloudStack system. Each NetworkGuru resources when VMs are gone. A Network goes through the following life cycles through the NetworkGuru. - When a guest network is created, NetworkGuru is asked to "design" the network. This means the NetworkGuru checks the parameters such as cidr, gateway, vlan, etc and returns a network that can work with those paremeters. Note that at this point the network is only a virtual network. It has not been substantiated with resources, such as vlan, to make the network functional in the physical environment. At this stage, the network is in Allocated state. - When the first virtual machine is about to be started and requires network services, the guest network needs to have resources to make it usable within the physical environment. At this time, the NetworkGuru is called with the implement() method to acquire those resources. - For every virtual machine starting in the network, the NetworkGuru is asked via the reserve() method to make sure everything the virtual machine needs to be functional in the network is reserved. - For every virtual machine being stopped in the network, the NetworkGuru is informed via the release() method to make sure resources occupied by the virtual machine is released. - If all virtual machines within the network have been stopped, the guest network is garbage collected. When a guest network is garbage collected the NetworkGuru is informed via the shutdown() method to release any resources it allocated to that network. - When a guest network is being deleted, the NetworkGuru is informed via the trash() method.
