[Kimchi-devel] [PATCH v2] [Kimchi] Feature request (#860): Support Guest Autostart

[Aline Manera]

Hi Bianca,

The patch looks good IMO but I'd ask you to add tests using the REST 
API. You can add those tests in test_rest.py file.

Something like:

1. Verify the 'autostart' parameter is correctly returned by the API GET 
/vms/*name*
2. Update the autostart parameter by the API PUT /vms/*name* {autostart: 
true/false} and confirm the changes were really made through GET 
/vms/*name* API
3. Do the test 2. for running and powered guests

Regards,
Aline Manera
