The process of snapshotting is in fact a qemu-img creation, you can easily see the process details on the compute node when you trigger a snapshot. However for the second point I don't remember right now where it's placed before being transfered, you'll find out easily with the qemu-img parameters. Hope it helps, Le 23/04/2015 22:00, Ross Lillie a �crit : Hi! I'm just trying to clarify my understanding of the image snapshot creation process. When snapshotting a running instance, the compute node must have sufficient disk space for the image to be created prior to uploading to Glance. Is this correct? Also, by default, during the snapshot creation on the compute node, where is the snapshot image being written? /tmp? /var/nova/instances? Thanks for your help!
