Re: Create VM - find out the NIC on KVM host connected to a Network switch
Why do you need this information on the MS? Can you detail the steps of the algorithm you are trying to design? E.g., AddVMtoNetwork: Step 1: Step 2: Step 3: Aha.

Re: Create VM - find out the NIC on KVM host connected to a Network switch
I have the NetworkGuru plugin(for orchestarting Juniper Switches) in the Management Server. (1)Create and Add first VM to Network. The Network is assigned a VLAN ID. (2)The implement() method of NetworkGuru plugin is invoked Here, I need to figure out the the vNIC to physical NIC mapping for this VM on the KVM host. By getting the physical NIC information, I can figure out the switch-port it is connected to using LLDP information on the switch -Pradeep On Tuesday, December 24, 2013 4:26 AM, Chiradeep Vittal chiradeep.vit...@citrix.com wrote: Why do you need this information on the MS?

Re: Create VM - find out the NIC on KVM host connected to a Network switch
On the KVM host you could parse the output of 'brctl show', but that is awkward to parse. Or you might be able to iterate through /sys/devices/virtual/net/* and work backwards from that.
