Metadata cpu policy dedicated

I have a compute node with 40 vcpus. I assigned 32 to nova scheduler and isolated those vcpus by using isolcpus. Now i am creating VM's using flavor metadata hw:cpu_policy=dedicated and hw:numa_nodes=1 but i can only SPAWN 6 instances of 4 vcpus. So i am using 24 vcpus. I can see in the horizon under hypervisors that i still have 8 vcpus. But i cannot SPAWN the 7th instance using the same flavor.
