<div dir="ltr"><div>Hi,</div><div><br></div><div>I have a two node + engine ovirt setup, and I was having problems</div><div>doing a live migration between nodes. I looked in the vdsm logs and</div><div>noticed selinux errors, so I checked the selinux config, and both the</div><div>ovirt-engine host and one of the nodes had selinux disabled. So I</div><div>thought I would enable it on these two hosts, as it is officially</div><div>supported anyway. I started with the node, and put it into maintenance</div><div>mode, which interestingly, migrated the VMs off to the other node</div><div>without issue. After modifying the selinux config, I then rebooted</div><div>that node, which came back up. I then tried to activate the node but</div><div>it fails and marks it as unresponsive.</div><div><br></div><div><div>----------8&lt;----------</div><div><br></div><div>2016-04-28 16:34:31,326 INFO</div><div>[org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient] (SSL Stomp</div><div>Reactor) [29acb18b] Connecting to</div><div>kvm-ldn-02/<a href="http://172.16.23.12">172.16.23.12</a></div><div>2016-04-28 16:34:31,327 ERROR</div><div>[org.ovirt.engine.core.vdsbroker.vdsbroker.GetCapabilitiesVDSCommand]</div><div>(DefaultQuartzScheduler_Worker-32) [ac322cb] Command</div><div>&#39;GetCapabilitiesVDSCommand(HostName = kvm-ldn-02,</div><div>VdsIdAndVdsVDSCommandParametersBase:{runAsync=&#39;true&#39;,</div><div>hostId=&#39;b12c0b80-d64d-42fd-8a55-94f92b9ca3aa&#39;,</div><div>vds=&#39;Host[kvm-ldn-02,b12c0b80-d64d-42fd-8a55-94f92b9ca3aa]&#39;})&#39;</div><div>execution failed:</div><div>org.ovirt.vdsm.jsonrpc.client.ClientConnectionException: Connection</div><div>failed</div><div>2016-04-28 16:34:31,327 ERROR</div><div>[org.ovirt.engine.core.vdsbroker.HostMonitoring]</div><div>(DefaultQuartzScheduler_Worker-32) [ac322cb] Failure to refresh Vds</div><div>runtime info: org.ovirt.vdsm.jsonrpc.client.ClientConnectionException:</div><div>Connection failed</div><div>2016-04-28 16:34:31,327 ERROR</div><div>[org.ovirt.engine.core.vdsbroker.HostMonitoring]</div><div>(DefaultQuartzScheduler_Worker-32) [ac322cb] Exception:</div><div>org.ovirt.engine.core.vdsbroker.vdsbroker.VDSNetworkException:</div><div>org.ovirt.vdsm.jsonrpc.client.ClientConnectionException: Connection</div><div>failed</div><div>        at org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerCommand.createNetworkException(VdsBrokerCommand.java:157)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerCommand.executeVDSCommand(VdsBrokerCommand.java:120)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.VDSCommandBase.executeCommand(VDSCommandBase.java:65)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.dal.VdcCommandBase.execute(VdcCommandBase.java:33)</div><div>[dal.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.ResourceManager.runVdsCommand(ResourceManager.java:467)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.VdsManager.refreshCapabilities(VdsManager.java:652)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.HostMonitoring.refreshVdsRunTimeInfo(HostMonitoring.java:119)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.HostMonitoring.refresh(HostMonitoring.java:84)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.VdsManager.onTimer(VdsManager.java:227)</div><div>[vdsbroker.jar:]</div><div>        at sun.reflect.GeneratedMethodAccessor120.invoke(Unknown</div><div>Source) [:1.8.0_71]</div><div>        at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)</div><div>[rt.jar:1.8.0_71]</div><div>        at java.lang.reflect.Method.invoke(Method.java:497) [rt.jar:1.8.0_71]</div><div>        at org.ovirt.engine.core.utils.timer.JobWrapper.invokeMethod(JobWrapper.java:81)</div><div>[scheduler.jar:]</div><div>        at org.ovirt.engine.core.utils.timer.JobWrapper.execute(JobWrapper.java:52)</div><div>[scheduler.jar:]</div><div>        at org.quartz.core.JobRunShell.run(JobRunShell.java:213) [quartz.jar:]</div><div>        at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:557)</div><div>[quartz.jar:]</div><div>Caused by: org.ovirt.vdsm.jsonrpc.client.ClientConnectionException:</div><div>Connection failed</div><div>        at org.ovirt.vdsm.jsonrpc.client.reactors.ReactorClient.connect(ReactorClient.java:157)</div><div>[vdsm-jsonrpc-java-client.jar:]</div><div>        at org.ovirt.vdsm.jsonrpc.client.JsonRpcClient.getClient(JsonRpcClient.java:114)</div><div>[vdsm-jsonrpc-java-client.jar:]</div><div>        at org.ovirt.vdsm.jsonrpc.client.JsonRpcClient.call(JsonRpcClient.java:73)</div><div>[vdsm-jsonrpc-java-client.jar:]</div><div>        at org.ovirt.engine.core.vdsbroker.jsonrpc.FutureMap.&lt;init&gt;(FutureMap.java:68)</div><div>[vdsbroker.jar:]</div><div>        at org.ovirt.engine.core
