[libvirt] How to add uplink in esx virtual switch using libvirt

Hi, I have an ESXi server, on top of it I have created one VM whose IP address is 192.168.79.1. I want to connect to the VM on ESXi server from my host machine but I am not able to do it. I have created a network "networkforSC" and I have pasted my xml file content below but I am not able to add any uplink (how to add it?) . Below is the xml file of my node as well as the network which I am creating on my ESXi server *<domain type='vmware'>* *<name>testNode</name>* *<uuid>50115e16-9bdc-49d7-f171-53c4d7f91710</uuid>* *<memory>1048576</memory>* *<currentMemory>1048576</currentMemory>* *<vcpu>1</vcpu>* *<console>/dev/console</console>* *<os>* *<type arch='x86_64'>hvm</type>* *</os>* *<devices>* *<disk type='file' device='disk'>* *<source file='[datastore1] testNode/testNode.vmdk'/>* *<target dev='sda' bus='scsi'/>* *<address type='drive' controller='0' bus='0' unit='0'/>* *</disk>* *<controller type='scsi' index='0' model='lsilogic'/>* *<!--controller type='scsi' index='0'/-->* *<interface type='bridge'>* *<mac address='00:50:56:25:48:c7'/>* *<source bridge='VM Network'/>* *</interface>* *<interface type='bridge'>* *<source bridge='test'/>* *</interface>* *</devices>* *</domain>* ########################################## Network File: *<network>* *<name>networkforSC</name>* *<portgroup name='test'>* *</portgroup>* *</network>* I have checked the network which got created on the server. As I have not attached any uplink (vmnic0) I can not see it (I want to attach it). #esxcli network vswitch standard list * * *networkforSC* *Name: networkforSC* *Class: etherswitch* *Num Ports: 128* *Used Ports: 2* *Configured Ports: 128* *MTU: 1500* *CDP Status: listen* *Beacon Enabled: false* *Beacon Threshold: 3* *Beacon Required By:* *Uplinks:* *Portgroups: test* Can anyone please help me out in adding the uplink and also can anyone tell me whether I am going in a right direction so that I could ping my virtual machine created on ESXi server.
