I'm not entirely sure what the issue is here, but this doesn't sound
like a bug per sé. At least, it's not something an end user will
encounter.

Title:
Libvirt: Correct usage _guest_add_memory_balloon
Status in OpenStack Compute (nova):
Invalid
Bug description:
From the code, function _guest_add_memory_balloon in [1], if
mem_stats_period_seconds set to 0 or negative value, the memory usage
statistics will disabled.
Is mem_stats_period_seconds can control the virtual memory balloon device
added? Isn't it only control memory usage statistics?
The virtual memory balloon device will be added by Libvirt as a
default behavior.[2]
So the name "_guest_add_memory_balloon" maybe misleading.
