I am using Openstack JUNO, one of the ESX Cluster in my node is giving overcommit data in nova hypervisor-show command.

I can see, vcpu is 32 and vcpu_used is 65, how this overcommit data store in nova?

I gave cpu ration as 10.0, but as per my understanding, this ratio used by nova-scheduler to spanwn vm on particular host.
