Description of problem:
When running `hosted-engine --deploy` it crashes with `Failed to setup networks {'ovirtmgmt': {'nic': 'enp3s0f0', 'bootproto': 'dhcp', 'blockingdhcp': True, 'defaultRoute': True}}. Error code: "16" message: "Unexpected exception"`.  Looking in supervdsm.log reveals `No such file or directory: '/proc/sys/net/ipv6/conf/ovirtmgmt/disable_ipv6'`.


Version-Release number of selected component (if applicable): oVirt 3.6 RC3, VDSM 4.17.10.


How reproducible: Always


Steps to Reproduce:
1. Boot with `ipv6.disable=1` in the command line.
2. Install oVirt 3.6 RC3 and run `hosted-engine --deploy`

Actual results: Setup completes


Expected results: Setup crashes

I have a patch already that I am just submitting to Gerrit now.
Comment 3 Dan Kenigsberg 2015-11-03 07:09:25 UTC 
Thanks for your report Ollie. Would you specify how did you disable ipv6, and why? I'd like to asses how common is this condition.
Comment 4 Red Hat Bugzilla Rules Engine 2015-11-03 10:02:12 UTC 
This bug is not marked for z-stream, yet the milestone is for a z-stream version, therefore the milestone has been reset.
Please set the correct milestone or add the z-stream flag.
Comment 5 Ollie Armstrong 2015-11-03 10:44:08 UTC 
I booted with "ipv6.disable=1" as a kernel boot parameter to disable ipv6.  It's something that I do fairly frequently as my servers are in a ipv4 only DC, it tends to make things simpler.
Comment 6 Sandro Bonazzola 2015-12-23 13:41:05 UTC 
oVirt 3.6.2 RC1 has been released for testing, moving to ON_QA
