Hi,
At the moment there is no 'pre fetching'. It is a nice idea.
Thanks
Gary

Subject: [Openstack] image caching

Hi all,

Currently, when we deploy a new image, the first VM deployment with that new image to any particular compute node takes longer than normal because the image is not yet "cached" on the node.

Is there a mechanism for pre-caching/pushing new images to compute nodes? I'm thinking we could just force a VM deployment to each node, but wanted to check if there was a better way.
