are make in the compute node. So all this takes long an dis proportional to the image size. Is there any way to speed up this process? Is a SAN based backend the only way to go?
No, but if you have multiple compute nodes you will want to have them all share /var/lib/nova/instances on a fast NFS server. Make sure that your glance machine is as fast as possible too. I also mount /tmp from /dev/shm which makes the snapshot process more tolerable, but obviously this will require machines with lots of RAM to spare. The change I made that helped the most was to disable NBD. You have to do this in /etc/init/nova-compute.conf and just comment out the modprobe nbd line.
