RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 Radek Novacek 2011-09-05 12:45:26 UTC 
Are you sure that your rhsm configuration is correct? Do you have your system registered? Can you show your rhsm configuration? Maybe change prefix=/subscription to prefix=/candlepin in /etc/rhsm/rhsm.conf can help.

It should be correct. For stage env, we use /subscription instead of /candlepin.
I can register/subscribe using subscription-manager.

rhsm.conf is attached https://bugzilla.redhat.com/attachment.cgi?id=521498.



GET /candlepin/status/

{'content': '<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">\n<html><head>\n<title>404 Not Found</title>\n</head><body>\n<h1>Not Found</h1>\n<p>The requested URL /candlepin/status/ was not found on this server.</p>\n<hr>\n<address>Apache Server at subscription.rhn.stage.redhat.com Port 443</address>\n</body></html>\n', 'status': 404}
Comment 6 Keqin Hong 2011-09-05 13:04:17 UTC 
My system is registered. Otherwise, I couldn't use virt-who.
subscription-manger has exception handling which catches the exception when getting /subscription/status/. That's why I could use subscription-manager to register/subscribe.
Comment 7 Radek Novacek 2011-09-05 13:53:48 UTC 
> subscription-manger has exception handling which catches the exception when
getting /subscription/status/

Where do you get this information? I can't find it in subscription-manager code.

You are right, it has no exception handling for GET /subscription/status/
 (the ping cmd).
Sorry, I meant to say it had for GET /subscription/.

#connection.py

        """
        Load the list of supported resources by doing a GET on the root

        replaced later) If something goes wrong making this request, just
        leave the list of supported resources empty.
        """
        self.resources = {}
        try:
            resources_list = self.conn.request_get("/")
            for r in resources_list:
                self.resources[r['rel']] = r['href']
            log.debug("Server supports the following resources:")
            log.debug(self.resources)
        # Handle situations where the UEPConnection isn't actually usable:
        except Exception, e:
            log.warn("Error fetching supported resources, this "
                    "UEPConnection is likely not usable:")
            log.exception(e)
Comment 15 Radek Novacek 2011-09-07 06:44:12 UTC 
Since the /status/ might not be implemented sometimes, I'll put the ping command to exception block to avoid virt-who to fail.
Comment 16 Radek Novacek 2011-09-07 07:22:30 UTC 
Fixed in virt-who-0.3-2.el6.
Comment 18 Keqin Hong 2011-09-07 11:30:28 UTC 
Verified on virt-who-0.3-2.el6. PASS

Steps:
1. enable virt-who debug option in /etc/sysconfig/
VIRTWHO_DEBUG=1
2. # service virt-who restart

virt-who exited normally.
