-----------------------------------------
Resolution: Fixed
> NSX/Nicira Plugin does not support NSX v4.2.1

> Key: CLOUDSTACK-8956
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8956
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: VMware
> Affects Versions: 4.4.0, 4.5.0, 4.4.1, 4.4.2, 4.4.3, 4.5.1, 4.4.4
> Environment: OS: RHEL 6.6

> h3. Description of the problem:
> Prior to version 4.2. Nicira/VmWare NSX used a variation of Open vSwitch as
> means of integrating SDN into hypervisor layer. Cloudstack NiciraNVP plugin
> was written to support OVS as a bridge to NSX.
> In version 4.2 VMware introduced NSX vSwitch as a replacement for OVS in ESX
> hypervisors. It is a fork of distributed vSwitch leveraging one of the recent
> features of ESX called opaque networks. Because of that change the current
> version of NiciraNVP plugin doesn’t support versions of NSX-MH above 4.2
> specifically in Vsphere environment. Proposed fix will analyze a version of
> NVP/NSX API and use proper support for ESX hypervisors.
> vSphere hypervisor mode operations when NV is deployed onto NSX managed
> network changes:
> * Current mode. A portgroup = UUID of CS VM NIC is created on a local
> standard switch of the Hypervisor where VM is starting. VM nic is attached to
> that port group.
> * New mode. No additional port group is created on a HW. No port group
> cleanup is needed after VM/NIC is destroyed. VM is attached to 1st port group
> having the following attributes:
> ** opaqueNetworkId string "br-int”
> ** opaqueNetworkType string "nsx.network"
> If portgroup with such attributes is not found a deployment should fail with
> exception.
> h3. VMware vSphere API version from 5.1 to 5.5:
> Since vSphere API version 5.5,
> [OpaqueNetworks|https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.OpaqueNetwork.html]
> are introduced.
> Its description says:
> bq. This interface defines an opaque network, in the sense that the detail
> and configuration of the network is unknown to vShpere and is managed by a
> management plane outside of vSphere. However, the identifier and name of
> these networks is made available to vSphere so that host and virtual machine
> virtual ethernet device can connect to them.
> In order to connect a vm's virtual ethernet device to the proper opaque
> network when deploying a vm into a NSX managed network, we first need to look
> for a particular opaque network on hosts. This opaque network's id has to be
> *"br-int"* and its type *"nsx.network"*.
> Since vSphere API version 5.5
> [HostNetworkInfo|https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.host.NetworkInfo.html#opaqueNetwork]
> introduces a list of available opaque networks for each host.
> If NSX API version >= 4.2 we look for a
> [OpaqueNetworkInfo|https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.host.OpaqueNetworkInfo.html]
> which satisfies:
> * opaqueNetworkId = "br-int"
> * opaqueNetworkType = "nsx.netork"
> If that opaque network is found, then we need to attach vm's NIC to a virtual
> ethernet device which support this, so we use
> [VirtualEthernetCardOpaqueNetworkBackingInfo|https://www.vmware.com/support/developer/converter-sdk/conv55_apireference/vim.vm.device.VirtualEthernetCard.OpaqueNetworkBackingInfo.html]
> setting:
> * opaqueNetworkId = "br-int"
> * opaqueNetworkType = "nsx.netork"
