Subject: Re: provisioing issue

The vcenter-compute node not showing up in the hypervisors on openstack node. This is happening due to python-oslo.vmware package not getting installed in the vcenter-compute node.

Sarath,
Please proceed with Kolla_globals option of “enable_nova_compute” set to no, and fix the vcenter-compute node by installing python-oslo.vmware package (apt-get inatll python-oslo.vmware) and restart nova-compute service.

Amudha,
This problem is only seen with ocata.
We do not explicitly install python-oslo.vmware during provisioning. The packages we install with nova-compute are [contrail-setup, nova-compute, python-bitstring]. Is it possible that newton nova-compute brings python-oslo.vmware as dependency and ocata nova-compute doesn’t? Can you please check?

Below is the trace from failure:
