[vmware driver] VM deployment failed on non-vmware distributed virtual switch

[Feng Xi Yan]

We are using a Cisco Nexus 1000v DVS, which is not a normal VMWare Distributed Virtual Switch

And we got following error when deploying a VM:

'VMwareDriverException:
Required property switchUuid is missing from data object of type DistributedVirtualSwitchPortConnection

Reason:
The reason is that Cisco Nexus 1000v DVS' type is(Managed Object:DistributedVirtualSwitch ) , which is not a normal VMWare Distributed Virtual Switch(Managed Object:VmwareDistributedVirtualSwitch ).
But the vmware driver is try to fetch the uuid based on type (Managed Object:VmwareDistributedVirtualSwitch ).
dvs_props = session._call_method(vim_util,
                                "get_dynamic_property",
                                props.distributedVirtualSwitch,
                                "VmwareDistributedVirtualSwitch", "uuid")

This code only works on normal vmware dvs, but not works on other types.

This was found in icehouse, and surely same situation in juno, kilo.

I will make a change in icehouse, and upstream to juno and kilo.

[Feng Xi Yan (yanfengxi)]

From the vmware sdk, we got following messages:

A DistributedVirtualSwitch is the base distributed switch implementation. It supports a VMWare distributed virtual switch and it supports third party switch implementations.

A VmwareDistributedVirtualSwitch is a sub-type of DistributedVirtualSwitch, and only supports a VMWare distributed virtual switch.
