nitpick:  nguests will never be zero in LXC since we hardcode the
set of guests, so you can drop that part of the condition when pushing.

[libvirt] [PATCH v2] lxc: Refresh capabilities if they have never been initalized

2019-12-09 Thread Cole Robinson
Adjust virLXCDriverGetCapabilities to fill in driver->caps if it is
empty, regardless of the passed 'refresh' value. This matches the
pattern used in virQEMUDriverGetCapabilities

This fixes LXC XML startup parsing for me

v2:
Use the virQEMUDriverGetCapabilities like danpb suggested
