Subject Re: Create VM - find out the NIC on KVM host connected to a Network switch
Date Fri, 20 Dec 2013 06:16:23 GMT
Hi Chiradeep,
the LLDP output on the switch looks something like

Local Interface    Parent Interface    Chassis Id          Port info         
System Name
ge-0/0/21.0        -                   00:30:48:c9:54:26   eth1     
ge-0/0/20.0        -                   00:30:48:fd:e4:fc   eth1     
me0.0              -                   78:fe:3d:d7:f4:80  
ge-0/0/2.0         x2-sw39

Here  and 
are the KVM hosts connected to the switch
