2017-03-07 03:50:37 -0600 asked a question couldn't obtain the vcpu count from domain id

I followed the instruction of the newton installation procedure on Centos 7.Everything is ok before I lauched an instance. After the instance is created and used the "openstack server list" to show the status is active.But in the compute node's nova-compute.log file ,there always has the warning message :"couldn't obtain the vcpu count from domain id: 0fbed715-1c5b-4807-83ff-589246fd25d0, exception: Requested operation is not valid: cpu affinity is not supported". Then when I connect the instance using the URL,it show the error message:Failed to connect to server (code: 1006).

How can I do from that?
