Multi node setup doesn't show list of hypervisors

This needs confirmation and I lack a multinode cluster at present to verify. Can someone with a 3 node setup please confirm?

TIA.

root@ubuntu1:~/kolla# nova hypervisor-list
+----+---------------------+-------+---------+
| ID | Hypervisor hostname | State | Status |
+----+---------------------+-------+---------+
| 4 | ubuntu2 | up | enabled |
| 7 | ubuntu1 | up | enabled |
| 10 | ubuntu3 | up | enabled |
+----+---------------------+-------+---------+

Works fine over here. This a deploy from ~8 hours ago. I suspect there is something up with libvirt on your host.

Below is my multi node inventory file

# These initial groups are the only groups required to be modified. The
# additional groups are for more control of the environment.
[control]
# These hostname must be resolvable from your deployment host
control ansible_ssh_user=root
# The above can also be specified as follows:
#control[01:03] ansible_ssh_user=kolla

# The network nodes are where your l3-agent and loadbalancers will run
# This can be the same as a host in the control group
[network]
network ansible_ssh_user=root

[compute]
compute ansible_ssh_user=root
# When compute nodes and control nodes use different interfaces,
# you can specify "api_interface" and another interfaces like below:
#compute01 neutron_external_interface=eth0 api_interface=em1 storage_interface=em1 tunnel_interface=em1

[storage]
silpixa00394079 ansible_ssh_user=root

# You can explicitly specify which hosts run each project by updating the
# groups in the sections below. Common services are grouped together.

# Word of caution: Some services are required to run on the same host to

Sam, What branch you're trying. Also can you post config details about libvirt or your inventory

Your nodes are physical or virtual machines ?

Could you post the nova-* logs ?

Did you add the host names of each of your nodes in the /etc/hosts file?

no problems in Mitaka either, multi node setup here.

[root@controller01 ~]$ nova hypervisor-list
+----+------------------------------------------+-------+---------+
| ID | Hypervisor hostname | State | Status |
+----+------------------------------------------+-------+---------+
| 4 | kvsrv02.<removed> | up | enabled |
| 7 | kvsrv01.<removed> | up | enabled |
| 10 | kvsrv03.<removed> | up | enabled |
+----+------------------------------------------+-------+---------+

Prithiv, can you please verify kvm is OK on all nodes?

docker exec nova_libvirt virt-host-validate

I had another issue with VMs getting multiple IPs, but noticed that list of hypervisor was not working either. Found one node did not have virtualization (vt-x) enabled in BIOS. Once enabled, both issues resolved.
