Entity - tier/private gateway/public vlan range

Feature Specifications

Currently VPC support is already available for Xen, VMware, KVM. In 4.3 Hyper-V Hypervisor support is added to cloudstack. This feature is to support VPC on Hyper-V hypervisor.
In the current implementation of VPC the following features are supported.

Test Guidelines

Functional

• • All existing functionality test cases for VPC should pass 
  • only max of 8 vpc services (tiers, private gateway, different public vlan) are suportedOnly max of 7 vpc Entities are supported because Hyper-V supports only 8 virtual network adapters to VM (http://technet.microsoft.com/en-us/library/jj680093.aspx)
  • VPC VR will be created with 8 nics up front.
  • When new service entity is created and fails to configure the virtual nic, then "Fail to hot plug Nic" error will be shown
  • When a tier/private gateway has to be created, if there is an error while modifying the VPC VR Nic, then the command will be failed and database changes will be roll-backed.
  • When a tier/private gateway got created successfully, then the vlan specified by the CS will be assigned on the NIC and internally associated eth device will be configured and will be in "UP" state.
  • When a tier/private gateway got removed successfully, then vlan will be removed on the VR NIC and associated eth device will be configured to  "down" state.

w.r.t Hyper-V, it cannot support Hot-Nic plug to the VPC VR.Hyper-V can support Max of (8) Virtual Network Adapters.

So to overcome this limitation imposed by Hyper-V, VPC VR will be deployed with extra nics.

Hyper-V can support Max of (8) Virtual Network Adapters.

How the deployment for VPC will work when running in Hyper-V:
