Looking at your service list output, you only have a single compute
service, correct? So you have to resize to the same host, and the
placement service is saying that host has no space left for the resize
to the new flavor that you're attempting.

       Status: New => Invalid

  when deploy a instance work don't problem... but didn't resize flavor.
  the quota is fine, the service also for example nova-placement-api,
  nova-conductor, nova-compute, nova-scheduler all state up.
