ComputeHostNotFound_Remote: Compute host controller1 could not be found.

Hi community,

I have setup openstack pike on ubuntu 16.04 about half a year ago. It consists of controller1 ,controller2,compute1,compute2.

It already has three compute nodes : controller2,compute1,compute2 Now I want to add controller1 to compute nodes.

I set it up according to https://docs.openstack.org/nova/pike/install/compute-install-ubuntu.html.

But it fail to add controller1 to compute nodes. I try to boot a vm after I disabled controller2,compute1,compute2 It shows error: No Vaild host found .

/var/log/nova/nova-compute.log shows :

No compute node record for host controller1: ComputeHostNotFound_Remote: Compute host controller1 could not be found.

root@controller1:~# nova service-list --binary nova-compute |grep controller1

| bfdacdd5-ede8-488c-98c3-fcec2943c39b | nova-compute | controller1 | nova | enabled | up | 2018-08-06T07:21:18.000000 | - | False

but nova hypervisor-list does not shows controller1

root@controller1:~# su -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" nova ## does not find controller1

Found 2 cell mappings. Skipping cell0 since it does not contain hosts. Getting computes from cell 'cell1': 7eba3d3e-3886-48fd-828c-e5ef562b414f Found 0 unmapped computes in cell: 7eba3d3e-3886-48fd-828c-e5ef562b414f

Any hints is appreciated! Thank you !
