vNIC ordering inside VM

Using Folsom with Quantum Linux Bridge. When I launch VMs using nova boot command, I expect VMs to be created with eth0-eth3 in order of --nic argument provided in the command line. For example:

nova boot --image cdf63c19-4c75-481c-a86e-018384c313be --flavor 12345 --nic net-id=c4c5183a-d6a8-4555-a328-b2bb74fd2f82 --nic net-id=19ff69df-f62b-4375-92d3-eddf5f6ce983 --nic net-id=e7182f99-e4b8-4e06-9e04-bec5dad8347c --meta "host"="sd-1-a" --meta "myfixedip"="" my_multi_nic_vm

However, when VM gets launched, it appears that vNICs are ordered based on port id as visible with quantum port-list command.

Is there a way to control vNIC order inside VM?

Thanks for the reply. But your link appears to be related to logging only. I can't find anything related to vNIC ordering in there.
