In order to access some of the features needed for this and a subsequent post, the 1000v needs to be running the advanced edition. The advanced edition can be used on a trial basis and is enabled using this command:
N1000v-L3(config)# svs switch edition ?
advanced Advanced switch edition
essential Essential switch edition
QoS
The 1000v uses the same IOS MQC so this makes classification, marking and policing easier. Here is an example configuration:
ip access-list QOS-ACL
10 permit ip 1.0.0.0/8 2.0.0.0/8
class-map type qos match-any TEST-CLASS
match access-group name QOS-ACL
policy-map type qos QOS-POLICY
class TEST-CLASS
set dscp 26
police cir percent 50 bc 200 ms conform transmit violate drop
port-profile type vethernet TEST
service-policy output QOS-POLICY

Traffic Flows
This title is straight from the blueprint. I'm assuming this is focused pinning, vPC host mode, etc.
vPC Host Mode (vPC-HM)
This mode can be used for a port channel that connect to multiple upstream switches that aren't clustered. The 1000v divides the port channel into subgroups in which each represents one or more uplinks.
Links that connect to the same physical switch are bundled in the in the same subgroup automatically (using CDP).
When vPC-HM is used, each vEthernet interface is mapped to one of two subgroups using round robin. If the upstream switches do not support port channels, MAC pinning can be used.
Here is a diagram from the 1000v Interface Configuration guide
Virtual Ports from a VEM can be pinned to a particluar subgroup within the port channel.
MAC Pinning
When connecting to multiple upstream switches that don't support port channels, MAC pinning is preferred.
This feature modifies the existing algorithm for MAC pinning where the port-channel uses the port number (vmnic number) as the subgroup ID for an Ethernet member port.
The new algorithm assigns zero-based logical subgroup IDs to Ethernet member ports. The member port that has the lowest port number (vmnic number) is assigned subgroup ID 0.
Network State Tracking
Network state tracking identifies link failures and allows traffic to be re-routed to active interfaces.
IGMP Snooping
IGMP snooping allows L2 switches to examine IGMP membership requests. This information lets the 1000v determine on which ports multicast traffic needs to flow. IGMP snooping is enabled by default and can be disabled either globally or on specific VLANs.
Here is an example of the default IGMP state of a VLAN
