Description Mike Burns 2011-12-02 21:23:20 UTC
+++ This bug was initially created as a clone of Bug #759631 +++

Description of problem:
A machine that is not registered but has virt-who installed and running will spawn a stack trace every minute to stderr.

Unable to read certificate, system is not registered or you are not root
1
Traceback (most recent call last):
  File "/usr/share/virt-who/virt-who.py", line 126, in _send
  File "/usr/share/virt-who/virt-who.py", line 104, in checkConnections
  File "/usr/share/virt-who/virt-who.py", line 81, in initSM
SystemExit: 1

SystemExit: 1
Unable to recover, retry in 60 seconds.

Version-Release number of selected component (if applicable):
virt-who-0.4-1.el5

How reproducible:
Always

Actual results:
Stack trace

Expected results:
virt-who either dumps only to a log or silently ignores the error if not registered.  

Additional info:

Found using RHEV-H 5.8.  Simply boot the machine and wait, you'll get the above stack trace every minute.

Traced this to virt-who.py

    # Print debugging output to stderr too
    logger.addHandler(logging.StreamHandler())

this should probably either be removed or indented to only be active if running in debug mode:


diff --git a/virt-who.py b/virt-who.py
