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 kernel: ovirtmgmt: port 2(vnet0) entered disabled state
Oct 18 14:50:39 mac5254002a783e systemd: Starting IPv4 firewall with iptables...
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.
