Unable to list nova instances using "IP" regex filter

[Mh Raies]

CLI guide of nova list tells that instances can be listed out with IP regex filter -

[raies@localhost devstack]$ nova help list
usage: nova list [--reservation-id <reservation-id>] [--ip <ip-regexp>]
                 [--ip6 <ip6-regexp>] [--name <name-regexp>]
                 [--instance-name <name-regexp>] [--status <status>]
                 [--flavor <flavor>] [--image <image>] [--host <hostname>]
                 [--all-tenants [<0|1>]] [--tenant [<tenant>]] [--deleted]
                 [--fields <fields>] [--minimal]

List active servers.

Optional arguments:
  --reservation-id <reservation-id>
                                Only return servers that match reservation-id.
  --ip <ip-regexp> Search with regular expression match by IP
                                address.
  --ip6 <ip6-regexp> Search with regular expression match by IPv6
                                address.
  --name <name-regexp> Search with regular expression match by name
  --instance-name <name-regexp>
                                Search with regular expression match by server
                                name.
  --status <status> Search by server status
  --flavor <flavor> Search by flavor name or ID
  --image <image> Search by image name or ID
  --host <hostname> Search servers by hostname to which they are
                                assigned (Admin only).
  --all-tenants [<0|1>] Display information from all tenants (Admin
                                only).
  --tenant [<tenant>] Display information from single tenant (Admin
                                only).
  --deleted Only display deleted servers (Admin only).
  --fields <fields> Comma-separated list of fields to display. Use
                                the show command to see which fields are
                                available.
  --minimal Get only uuid and name.

I am able to filter instances using their name regex but I am unable to filter with IP regex.
When I use complete IP only then IP instance of that IP can be listed but regex of IP does not work.

Steps performed by me are as -

1.

This we can see, Instances list with server regex could not found.

Actually neutron does not have regex-based queries feature for ip as Nova-network does. Its related to neutron. They have in their plan for the same.
