I install the openstack-ocata in one physical server(CentOS7.2). the controller and compute node all in it.

I created several instances, but now I have delete them, but in the Hypervisors there still have the Memory Usage and Local Disk Usage.

Why there is this issue? is the ocata bug or our configuration error?


If the Memory Usage is high, like upper, whether when create a new instance, it may can not find the usable host? (NoValidHost: No valid host was found.)

I create the instance get this issue, so I am suspect this is caused by the upper issue(Memory Usage high, but I have delete all the instances):

NoValidHost: No valid host was found.

# nova list
