Public bug reported:

This happens when I run any IPv6 tests from tempest.api.network locally. It doesn't cause test failures, but it does show a problem with the code. It happens sometimes in the OpenStack CI testing.

So it looks like the '--dhcp-range=set:tag0,2003::,static,86400s' part
is the problem because the subnet is 2003::/64.

There is a patch to wrap ipv6 addresses that are written to the hosts file with []. Maybe something similiar is needed for the command line, or ipv6 should be skipped for now.
