New subject: [PATCH] [Kimchi 1/2] Improve PCI passthrough performance
- This commit improves PCI passthrough performance by re-using the
device(s) model instead of creating new instances, which was
the source cause of a huge overhead.

New subject: [PATCH] [Kimchi 2/2] Replace device companion check before the passthrough
- Instead of checking the companion for each device (with performance
penalties when opening the Edit Guest window) we now check for
companions before plugging a device to a guest. Then, we popup
a confirmation window showing devices affected by such action and
asks for user confirmation.
