If i look at the number of vcpu available i.e Admin-->Hypervisors, I see 16 vcpu available. cpu_allocation_ratio is 16.0 which means i should have 256 vcpu (16pcpu * 16 ). Someone on irc suggested that dashboard is only reporting the stats as they are returned by "nova hypervisor-stats". I am wondering if there is a way to see actual number of vcpu available ?
