[ovirt-users] Error 500 when adding a new host

Good afternoon everybody. I'm using oVirt 4.4.10 at the moment. After activating Cinder, I believe that some packages were updated, which is causing some problems, one of them is occurring when I try to add a Host, then it shows a 500 error, the same is happening when editing a Host. The following error is happening in the server.log: 2023-03-16 10:54:39,651-04 ERROR [io.undertow.servlet] (default task-133) Exception while dispatching incoming RPC call:
