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.

Red Hat Product Errata RHBA-2011:1695 0 normal SHIPPED_LIVE subscription-manager bug fix and enhancement update 2011-12-06 01:23:29 UTC

Description John Sefler 2011-07-28 15:25:50 UTC
Description of problem:
A side affect of commit https://bugzilla.redhat.com/show_bug.cgi?id=722248#c1 is that on a bare metal host machine, the fact for virt.host_type is getting set to "Unknown" when the the value of "" returned from virt-what is actually a good value implying that this is NOT a virtual guest.  (see man virt-what)

On a bare metal machine prior to commit https://bugzilla.redhat.com/show_bug.cgi?id=722248#c1 ...


# subscription-manager facts --list | egrep "virt\."
virt.host_type: 
virt.is_guest: False

^^^ These results were correct


On a bare metal machine after commit https://bugzilla.redhat.com/show_bug.cgi?id=722248#c1 ...

# subscription-manager facts --list | egrep "virt\."
virt.host_type: Unknown
virt.is_guest: False

^^^ These results are wrong


I beleive the best fix for this bug is to make the following code change to hwprobe.py:


277     def getVirtInfo(self):
278         virt_dict = {}
279 
280         try:
281             host_type = self._get_output('virt-what')
282             virt_dict['virt.host_type'] = host_type
283             # If this is blank, then not a guest
284             virt_dict['virt.is_guest'] = bool(host_type)
285 #jsefler suggests these 2 lines as a fix for this bug
286             if host_type == "":
287                 virt_dict['virt.host_type'] = "Not Applicable"
288         # TODO:  Should this only catch OSErrors?
289         except:
290             # Otherwise there was an error running virt-what - who knows
291             virt_dict['virt.is_guest'] = 'Unknown'
292 
293         self.allhw.update(virt_dict)
294         return virt_dict


On a bare metal machine after jsefler's suggested fix ...

# subscription-manager facts --list | egrep "virt\."
virt.host_type: Not Applicable
virt.is_guest: False



NOTE: this fix is also translated to the subscription-manager-gui facts
