First, this is a python-novaclient bug, not a nova bug.

Second, the call to get the server isn't for checking if the server
exists, it's because the CLI allows passing in a server name or ID, and
if it's a name, we have to look it up to get the ID to pass to the GET
/servers/{server_id/migrations API:

https://github.com/openstack/python-
novaclient/blob/10.1.0/novaclient/v2/shell.py#L3330

So I don't think this is a valid bug.

Title:
  while executing ServerMigrationList use-case an extra call is made to
  nova-api for fetching server details.

Status in python-novaclient:
  Invalid

Bug description:
  An extra call is made to nova-api for fetching server details to check it's existence. 
  Once existence of server is confirmed, after that  "server migration list" call is made to nova-api.
  In existing nova cli code flow, if server does not exist and "nova server-migration-list {server-id}" is invoked, it will display error to user and will not execute server migration list API call. 
  In contrary, if user directly execute curl command to fetch migration list for server which does not exists, then also same error message is displayed to user.
  So, it seems extra call to check existence of server.

  Solution:
  Code should be improved to eliminate extra nova-api call to check server existence before executing concerned command.
  Server migration list can directly be executed through curl to avoid extra call to check server existence before invoking server migration list.
  curl -g -i -X GET http://{hostip}:8774/v2.1/{tenant_id}/servers/{server_id}/migrations  -H "Accept: application/json" -H "X-OpenStack-Nova-API-Version: 2.23" -H "X-Auth-Token:{token_id}".
