[Kimchi-devel] [PATCH 1/5] Granular Task Queries: Backend

Christy Perez christy at linux.vnet.ibm.com
Fri Feb 27 15:41:07 UTC 2015


Currently, you can only filter tasks by their state (running) or
their URL. If you want to see cloning tasks, you query all running
vm-related tasks.

It also adds descriptions for non-vm-related tasks.
