Cloned from launchpad blueprint https://blueprints.launchpad.net/horizon/+spec/horizon-massive-nova-instance-search.
The current admin page for nova instances does client side search and forces users to do a lot of paging in order to find an instance. A deployment of any scale (think 1000s of instances) struggles with this type of user interaction.
I propose adding a page that looks similar to the current instances page in the admin dashboard, but provides instance searching for a variety of parameters..... project id, host, ip address.... etc. The common ways an admin would locate an instance via CLI should be available in the UI.
