When adding host to engine failed, wait for 2 mins, the rhvh were recover automatically and status up on rhvm side. Expected results: 1. After step#3, the host can be added to engine successfully without any error Additional info: Modify "VDSM/disableNetworkManager=bool:False" in /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf, also caught this erro

No such issue in previous build, so it'a regression.
Is this reproducible on RHEL?
(In reply to Ryan Barry from comment #5) > Is this reproducible on RHEL? Yes, also can be caught on RHEL7.3 [root@rhel7 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 7.3 (Maipo) [root@rhel7 ~]# rpm -qa|grep vdsm vdsm-hook-vmfex-dev-4.19.2-2.el7ev.noarch vdsm-python-4.19.2-2.el7ev.noarch vdsm-jsonrpc-4.19.2-2.el7ev.noarch vdsm-cli-4.19.2-2.el7ev.noarch vdsm-yajsonrpc-4.19.2-2.el7ev.noarch vdsm-4.19.2-2.el7ev.x86_64 vdsm-xmlrpc-4.19.2-2.el7ev.noarch vdsm-api-4.19.2-2.el7ev.noarch
Does it happen only with disableNetworkManager=False?
It seems that vdsm was in recovery mode: 2017-01-22 04:10:19,584-05 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.PollVDSCommand] (org.ovirt.thread.pool-7-thread-22) [67c967f0] Error: Recovering from crash or Initializing
Proposing as blocker for 4.1
(In reply to Dan Kenigsberg from comment #7) > Does it happen only with disableNetworkManager=False? Yes, in bug description "VDSM/disableNetworkManager=bool:False" in /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf.
Maybe not clear for additional info in the description, I should clarify that: I have tested below two scenarios, both encounter this bug. 1. "VDSM/disableNetworkManager=bool:False" in /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf After registering engine, the NM daemon is kept running. 2. "VDSM/disableNetworkManager=bool:True" in /etc/ovirt-host-deploy.conf.d/90-ngn-do-not-keep-networkmanager.conf After registering engine, the NM daemon is not running.
Hi I managed to reproduce this issue one time few days ago(with rhel server). Note that although the host was auto recovred the 'ovirtmgmt' network wasn't persisted and such host won't come up after reboot.
I am not seeing any issue on the networking side. Setup started @04:10:20 and ended @04:10:49 It took 20sec for DHCP to return the same IP on the management bridge and then connectivity check succeeded and returned back an OK. I am not clear what happened on the engine side, it makes sense for it to loose connectivity for 20sec but it should have recovered. the pings seem to have arrived to VDSM (see vdsm.log) so I am not clear what are the errors in the Engine logs.
I suggest to attempt to reproduce it with the latest jsonrpc in version 1.3.8.
We seem to have several points that need treatment (but not related): - On host deploy, when starting vdsmd, it may take a while until VDSM can actually service incoming requests (it is in recovery mode). It makes sense to block on service start until VDSM is indeed ready to accept requests. - Based on Engine logs, the first flow of setupNetworks attempt (after the deploy scripts) failed because of VDSM being in recovery state and it has not handled such a case (Engine does not expect VDSM to be in recovery state). - It is not exactly clear why, but after the first flow failure mentioned above another flow is created and issues an additional setupNetworks that is handled by VDSM but fails on Engine side due to RPC connectivity problem. For the 2nd point, yzaspits is posting a proposed patch.
