Hi everyone, We have a openstack with one region and more than 100 compute nodes. We are using ceph for block storage. I don't know why my instance was provisioned too slow: more than 1 minutes. Nova compute log: Took 56.47 seconds to build instance. So I would like to optimize and speed up instance build time.
