Hi Sateesh,

As we increase the cluster size, I wonder not having the management network=
 on DVS might be an issue. I would strongly suggest we consider this. I als=
o spoke to some folks who are more knowledgeable with customer implementati=
ons and they also say this would be an issue.

As you know, we have a separate feature being discussed - support for PVLAN=
 - so, PVLAN support via DVS is a must-have requirement..

Hari

During discuss thread over the FS (in 72 hours time frame), there were no c=
omments over this point. Hence the implementation has assumed a 'No' and ex=
cluded management network traffic over dvSwitch. I think enterprises prefer=
 to leave management traffic over standard vSwitch which is added by defaul=
t during vSphere installation.
Would like to hear if otherwise? We can extend the support.

Current implantation just configures VLAN over a dv port group (virtual net=
work).
Virtual network orchestration over VMware resource is looking only for unta=
gged or tagged isolated VLAN networks.=20
Kindly let me know If there is any requirement for PVLAN enabled networks.=
=20
The current implementation can be definitely extended to support it.
