----------------------------------------

             Summary: Vmware resource: incorrect parsing of device list to find ethener index
of plugged nic
                 Key: CLOUDSTACK-9491
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9491
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.6.0
            Reporter: Murali Reddy
             Fix For: 4.10.0.0, 4.9.2.0, 4.8.2.0


In VmwareResource.java, there is logic ( in findRouterEthDeviceIndex) to find ethernet interface
a mac address is associated with.

After NIC in plugged in to a Vm through vSphere, it takes some time for the device to show
up in the guest VM.

Logic loops through the device list obtained from /proc/sys/net/ipv4/conf from the VM, and
matched againest mac.

However '/proc/sys/net/ipv4/conf'  is not refreshed, heve logic loops through old device list
always.

In addition there is no exception thrown and error is maked by sending -1. 

Eventually, VR scripts are getting -1 as device number causing failure in processing the scripts.
