How to find VIF corresponding to VM in xenserver

The below logs are taken from the cloudstack configured xenserver.
In cloudstack Advanced zone with isolated network is created and deployed VM in isolated network.

List of VMs running in xenserver:


[root@Rack1Pod1Host22 ~]# xe vm-list  power-state=running params=dom-id,name-label,uuid
uuid ( RO)          : 20238d97-f5cb-9de7-5605-771f2052b051
    name-label ( RW): s-1-VM

        dom-id ( RO): 0

VIF (virtual interface) of a VM in xenserver

-- vif# corresponds to VM i-2-3-VM is vif7.0 where 7 is the domainID
The VIFs belongs VM will have VIFx.y where x is domain ID and y starts from 0

#ifconfig

          RX bytes:1098 (1.0 KiB)  TX bytes:12734 (12.4 KiB)

The v-2-VM VM is having dom-id 2 and its interfaces are shown below ifconfig output with vif2.0, vif2.1, vif2.2


    name-label ( RW): v-2-VM
        dom-id ( RO): 2
