Fuel UI allows to configure only 10 NICs

[Alexander Rubtsov]

Steps to reproduce:
1. Launch node that has more than 10 NICs to bootstrap mode
2. Mark this node on the "Nodes" tab and click "Configure interfaces"

Expected result:
I can map network roles to any interface

Actual result:
I can map network roles only to interfaces eth0-eth9

Issue is not reproducible on Fake UI

[Vitaly Kramskikh (vkramskikh)]

Most likely an agent issue. UI doesn't have such kind of limitations

    Fix interface type check in nailgun agent

    The regular expression used in ohai to determine interface type
    doesn't work with interfaces containing more than one digit (e.g.
    eth10). Consequently the "type" is returned as eth1 instead of eth
    for all interfaces above eth9 and the agent skips them.

    Ohai bug here: https://tickets.opscode.com/browse/OHAI-571

Do we have a fix for ohai? Otherwise how proposed fix https://review.openstack.org/88687 is going to deal with this issue?

[Ryan Moe (rmoe)]

This problem was caused because ohai has a broken regex (see ohai bug in the commit message). What happens is that when you have an interface like eth10 ohai sets the type to "eth1" instead of "eth". The agent was skipping all interfaces != "eth". This change works around the issue by only skipping interfaces that don't start with "eth". This way interfaces with type |eth1", or "eth2" or whatever won't be skipped.
