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. Here's where I need this info

But how do we convey this information to the Mgmt Server ? Without making any enhancements to MgmtSvr/Agent , is it possible to achieve this? -Pradeep On Saturday, December 21, 2013 4:19 AM, Chiradeep Vittal <chiradeep.vit...@citrix.com<mailto:chiradeep.vit...@citrix.com>> wrote: 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.
