The video walks you through Cisco Nexus 1000V installation in Layer 3 mode. We will explore various methods to install both VSM and VEM so you can be aware of steps involved and determine which method will work best in your deployment. This lab takes what we have discussed on the Nexus 1000V introduction video, and applies them into actual implementation. 

In part 2, we will be installing VEM and migrate our VM behind the VEM.
You can also find detailed discussion on deployment options and more extensive comparison between Layer 2 and Layer 3 mode at the link below.

Great video. It helped me to deploy L3 in our enviornemnt.

I just used one vlan for
VSM-Mgmt
VSM-Control
VSM-Packet
VEM-Control
It is working... is it okay?

Using three VLAN is just Cisco recommended practice. Using a single VLAN would sure work.

Do I need to give IP to Vmotion & Fault Tolerance interfaces in ESXi ?

Yes, those are VMkernel interfaces which require IP.

So , to summarize .. I need only VSM Mgmt , VSM Control (HA) & VEM Control interface to implement L3 ... Is this correct ?

How many IP(s) I require ?

Correct, One for VSM Mgmt, None for HA (L2 only), One per ESXi host for VMkernel VEM Control. 

I have production env. planning to move from L2 to L3 ,can you please help one this and also like to know will there be any Impact on VM's or ESXi while migration from L2 to L3

Since you need to reconfigure both VSM and VEM, most likely they will lose communication to each other but VEM should continue to forward traffic. If you have a large number of ESXi that can potentially be impacted, you might want to consider labbing this out so you will know exactly what wil happen.
