[Bug 2111895] [NEW] nova-api does not return | vCPUs Used | vCPUs | Memory MB Used | Memory MB | in output of "openstack hypervisor list --long"

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

In Train release output of "openstack hypervisor list --long" included
all the columns:

Now, starting from Wallaby, Nova API does not return below columens: 
- vCPUs Used
- vCPUs
- Memory MB Used
- Memory MB

And the output looks like this:

Using OpenStack SDK I checked what we get back from Nova API and these extra information are missing in the output from Nova API:


>>> for server in conn.list_hypervisors():
...     print(server)
...
