The fix here should be to output a more reasonable message when virt-who is reloaded and no longer registered. The issue is that for configurations that do not specify what credentials to use, virt-who will try to use the certs on the system if it is registered. In this case we should print something more like the following to stderr: "SubscriptionManagerUnregisteredError: Unable to read certificate, system is not registered or you are not root" When debug is on, a stack trace is generated [as expected]. When debug is not on, then only the error message is shown: "virtwho.manager.subscriptionmanager.subscriptionmanager.SubscriptionManagerUnregisteredError: Unable to read certificate, system is not registered or you are not root" This is the intended behavior. If the registration happens between virt-who runs, the system returns to normal processing. |
Description of problem: When virt-who work at xen mode, it will show "ConnectionError: ('Connection aborted.', error(4, 'Interrupted system call'))" after unregister system. Version-Release number of selected component (if applicable): virt-who-0.17-10.el7.noarch subscription-manager-1.17.10-1.el7.x86_64 python-rhsm-1.17.6-1.el7.x86_64 How reproducible: Always Steps to Reproduce: 1. Register system to satellite6 2. Configure virt-who run at xen mode and restart virt-who service ,virt-who can send mapping info successfully to server.
