We are using Open Stack Liberty. We launched at least 8-9 instances with various Linux flavors but we try to launch more instances it gives the error "Exceeded maximum number of retries. Exceeded max scheduling attempts 3 for instance ...". Public IP gets assigned and after IP assignment above error appears. Any clue

check if the DB is accessible using passwords in nova.con, also see the logs in /var/log/nova. Furthermore check whether enough resources are available like CPU, RAM, DISK etc.

Dear Jamie, In our cloud we have 20 compute nodes. Each has 24 VCPUs (= 480 VCPS), Sufficient memory and storage. I have checked db access for nova.I have checked /var/log/nova/nova-conductor.log. It says could not open disk image /var/lib/nova/instance/xxx/disk

Could you check glance log files ? nova-compute ? If nothing, then try switchig on debugging on nova.conf?
