Migrate instance from syspanel
In the syspanel, I would expect the ability to migrate a single server.
Steps:
0) login as admin
1) go to syspanel
2) go to instances and find the instance you want to migrate
3) click migrate

The novaclient library exposes the API:
$ nova help migrate
usage: nova migrate <server>
Migrate a server.
Positional arguments:
<server> Name or ID of server.

Migrate an instance from the admin dashboard

- This is a 2-steps process

I think highlighting that this is a 2-step process in the UX is a very important part of the blueprint, additional ideas in that area are also welcome.
Since I had to look it up initially... 'nova migrate' performs a "dead" migration on a server, essentially creating a snapshot of the drive, transferring it to a new server and rebooting. [0] The new host is selected by the scheduler. [1]

Some considerations:
- Migrate and resize share a code path (as in, migrate is a special kind of resize or vice-versa...). When the migration begins, the default status messages are "Resize migrating", "Verify resize" etc which could be confusing. Ideally the UI should show migration-specific messages.
- Migrate/resize is a 2-step process. After the resize a resize-confirm or resize-revert command needs to be manually entered. This 2-steps process will need to be reflected in the UI.
Additionally there's an auto-confirm config option (resize_
- By default migrate is an admin-only option. This could be changed by updating nova's policy.json -- taking this into account may be work for another, bigger blueprint though... The confirm/revert step isn't restricted to admins.
