Comment 3 for bug 1813198

Oh it's called from here:

http://git.openstack.org/cgit/openstack/tempest/tree/tempest/common/utils/linux/remote_client.py#n140

Looks like right before the failure we run that command:

2019-01-24 18:26:06,439 5033 DEBUG [tempest.lib.common.utils.linux.remote_client] Remote command: set -eu -o pipefail; PATH=$PATH:/sbin; ip -o addr | awk '/10.1.0.3/ {print $2}'

But it doesn't log the result.

I'm also seeing this in the console output:

"Failed to update DNS nameservers"

Looks like this started around Jan 20:
