Hi Bathri,
The nova api has moved into nova code base. So, removing the api-site and adding nova.

A bug report with an assignee should be 'In Progress' status.
So set 'In Progress' to nova.

[Takashi Natsume (natsume-takashi)]

This bug report has been 'In Progress' status for a year, but there is no activity.
So set it back to 'New' status and 'Undecided' importance.
