Hi all,
I'm considering to extend the Nova-Compute API in order to provide
image-prefetching capabilities to OS.
In order to allow image prefetching, I ended up with the need to add three
different APIs on the nova-compute nodes:
1. Trigger an image prefetching
2. List prefetched images
3. Delete a prefetched image
About the point 1 I saw I can re-use the libvirt driver function
_create_image() to trigger the image prefetching. However, this approach
will not store any information about the stored image locally. This leads
to an issue: how do I retrieve a list of already fetched images? A quick
and simple possibility would be having a local file, storing information
about the fetched images. Would it be acceptable? Is there any best
practice in OS community?
Any ideas?
Ty,
Al.
