Hi Anton,
thanks for your feedback, I'm trying to reproduce this bug.

What ESX version are you running?

When the VM is running, what OpenNebula's action do you use to shutdown the running VM (stop, pause, poweroff, poweroff --hard, undeploy, undeploy --hard)?. Would it be possible to send me the oned.log and the VM log when this problem happens?

Thanks in advance

Though we could not reproduce in testing, the only possible way that a NIC was duplicated would be created by the following condition:

if nic.elements["MAC"].text dv.macAddress and nic.elements["BRIDGE"].text dv.deviceInfo.summary

It seems that dv.deviceInfo.summary would not contain the bridge name in certain cases that cannot be determined so the condition is set to:

if nic.elements["MAC"].text == dv.macAddress

which fixes the problem for an affected user. A PR has been created.
