[ovirt-users] Python-SDK4: How to list VM user sessions?

[Juan Hernández]

I have been trying to reproduce this and I wasn't able. In theory the
404 error that you get should only happen if the virtual machine doesn't
exist, but that isn't the case.

Can you check the server.log file and share the complete stack traces
that should appear after the "HTTP 404 Not Found" message?
