Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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-2015:1911 0 normal SHIPPED_LIVE Satellite 6.1.3 bug fix update 2015-10-15 22:19:19 UTC

Description Jan Hutař 2015-08-03 20:21:48 UTC 
Description of problem:
Provisioning host in OpenStack produces SELinux AVC.


Version-Release number of selected component (if applicable):
Satellite-6.1.0-RHEL-6-20150731.1-Satellite-x86_64


How reproducible:
always (about 2 of 2 attempts)


Steps to Reproduce:
1. Setup Sat6 with OpenStack compute resource
2. Provision host
   # hammer --username 'admin' --password 'changeme' host create --name 'OpenStack2' --hostgroup-id '1' --compute-resource-id '2' --puppet-ca-proxy '<fqdn>' --puppet-proxy '<fqdn>' --puppet-classes qaredhattest --location-id '2' --organization-id '1' --provision-method 'image' --owner 'admin' --compute-attributes 'nics=[],flavor_ref=1,security_group=<group>,network=public,image_ref=<ref>'

Expected results:
There should not be any AVC


Additional info:
To me it looks like it is not breaking anything, but having AVCs logged is not nice.
Comment 4 Jan Hutař 2015-08-05 07:03:30 UTC 
Looks like there is same issue when creating OpenStack compute-resource:

# hammer --username admin --password changeme compute-resource create --name 'openstack' --provider Openstack --url 'http://<openstack>:5000/v2.0/tokens' --user '<user>' --password '<pass>' --tenant '<tenant>' --organization-ids 1 --location-ids 2

Comment 5 Jan Hutař 2015-08-05 20:22:52 UTC 
This is fatal on RHEL7 - creating OpenStack compute resource fails with SELinux in Enforcing.
Comment 10 Lukas Zapletal 2015-08-06 14:35:02 UTC 
This should have been solved with https://bugzilla.redhat.com/show_bug.cgi?id=1249788
Comment 11 Lukas Zapletal 2015-08-07 07:30:20 UTC 
Sorry I meant https://bugzilla.redhat.com/show_bug.cgi?id=1136991
Comment 17 Kedar Bidarkar 2015-10-07 17:01:14 UTC 
Verified we are now able to add openstack compute resource without disabling selinux.
