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.

Description Simone Tiraboschi 2016-11-10 16:25:27 UTC 
Description of problem:
Something prevents the ebtable_nat module from being autoloaded.

A rules on the ebtables nat chain fails to apply:

Oct 18 14:50:39 mac5254002a783e journal: internal error: Failed to apply firewall rules /usr/sbin/ebtables --concurrent -t nat -N libvirt-J-vnet0: The kernel doesn't support the ebtables 'nat' table.

Iptables got stopped:
Oct 18 14:50:39 mac5254002a783e kernel: ip_tables: (C) 2000-2006 Netfilter Core Team
Oct 18 14:50:39 mac5254002a783e iptables.init: iptables: Unloading modules: [  OK  ]
Oct 18 14:50:39 mac5254002a783e systemd: Stopped IPv4 firewall with iptables.

And so the management bridge and so the RHHEV engine VM:
Oct 18 14:50:39 mac5254002a783e kernel: ovirtmgmt: port 2(vnet0) entered disabled state
Oct 18 14:50:39 mac5254002a783e kernel: device vnet0 left promiscuous mode

Oct 18 14:50:39 mac5254002a783e kvm: 0 guests now active
Oct 18 14:50:39 mac5254002a783e kernel: nf_conntrack version 0.5.0 (65536 buckets, 262144 max)
Oct 18 14:50:39 mac5254002a783e systemd-machined: Machine qemu-1-HostedEngine terminated.

Version-Release number of selected component (if applicable):


How reproducible:
It seams specific just to hosts deployed from satellite and it seams pretty reproducible.

Steps to Reproduce:
1.
2.
3.

Actual results:
The RHEV engine VM got terminated and so the hosted-engine setup got stuck.

Expected results:
It will be possible to deploy hosted-engine.

Additional info:
It affects QCI.
Comment 5 Simone Tiraboschi 2016-11-17 09:47:23 UTC 
We saw it also on an host which hasn't been deployed from the satellite template.
Closing this one and opening a new one on libvirt for the interaction with ebtables.
