Nova-Compute not using cachemanagement
I'm wondering how do glance and nova interact when caching is enabled. I tried to install NOVA+GLANCE on a separate node instead of the controller and what I can observe by network monitoring is that, even if I run
glance-cache-manage queue-image glance-cache-prefetcher
(and the image actually gets stored on the local node), when launching a new vm with
nova boot --image xxxx
I see the image is downloaded by the central repository instead of the local glance cache.
Question is: why?
