Attaching Physical Ports to the Nexus 1000v
- Connect to vCenter using the vSphere Client
- Go to Networking Inventory and select the Nexus distributed virtual switch (dVS).
- Right click on the Nexus and choose add host.
- Select the host and vmnic(s) to use and change their DVUplink port group to system-uplink (or what you named the system uplinks in your port group on the Nexus) for the system uplink ports and vm-uplink for the VM networking ports.
- Click next and choose not to migrate the vmk0 or VMs. (I prefer to verify the Nexus 1000v's operation before migrating anything.)
- Click Finish.
- Repeat for all hosts in the cluster.
Migrating vmk0 Interfaces to Nexus
Once you have added a few test VMs to the Nexus and are certain that the Nexus 1000v is working properly, it's time to migrate the last physical NIC from the vSwitch to the Nexus 1000v and with it the vmk0 interface used for vMotion and VMWare host management. Keep in mind that if you don't need this NIC for bandwidth reasons, it is not mandatory to move these services to the Nexus 1000v.
- Connect to vCenter using the vSphere Client.
- Go to Networking Inventory and select the Nexus dVS.
- Right click on the Nexus and choose manage host.
- Select the hosts and click next twice.
- Click on the destination port group for the vmnic used by vmk0 and choose the Nexus port group.
- Click next and then finish without migrating VMs.
You will need to repeat this for each host in the cluster. Leave the host with the active VSM for last and make sure to migrate it's NICs to the Nexus before disconnecting the vSwitch from the vmnic.
