how nova-compute manage images in <instances_path>

Asked by li,chen on 2013-05-24

When nova boot an instance, the image will copy from glance to nova-compute's <instances_path>.
If we have many images, then after the cloud run a really long time, isn't all images in glance will have a copy at compute nodes' <instances_path> ? Isn't the space in <instances_path> will not enough ?

Thanks.

There is a periodic_task named "_run_image_cache_manager_pass" in Nova-compute.
Its utility is to manage the driver's local image cache.

Please check it~~
