I created a flavor called s1.16core with ID=10, then I created a flavor called s1.8core with ID=11. I changed my mind and deleted both flavors. Then I created a flavor s1.8core with ID=10. When I launch an instance using flavor ID=10, it shows the flavor labeled s1.16core instead of s1.8core.
In both the dashboard and in nova flavor-list output, there is no s1.16core flavor - only the flavor with ID=10 called s1.8core.
Perhaps this is a cleanup issue in OpenStack? Any ideas on how to resolve this?
