Hi, I have a multi-nodes openstack environment, including a control node running Glance, nova-api, nova-scheduler, nova-network, rabbitmq, mysql, keystone and dashboard services, and two compute nodes running nova-compute and nova-network services.
When someone is taking a snapshot for his/her VMs, the Openstack system looks like very busy and it will take a long time (at least 3 to 4 minutes in this situation and regular time is in 30 seconds) to create a VM. I wonder is there any solution to optimize this system so that it can response quickly. it will be much appreciated if someone could give me some hints about this. Thanks, Sam
