I'm trying my python cli, I send the following command using python sdk 3.6.3.0 to reinstall an host: > POST /api/hosts/db240f83-9266-4892-a6d2-8ac406cadfb1/install HTTP/1.1 ... > <action> > <host> > <override_iptables>false</override_iptables> > </host> > <ssh> > <port>22</port> > <fingerprint>SHA256:3wKEADIgpAnX1cF/EnvdVODBKvU/FaaFKqHndlYxl8k</fingerprint> > <authentication_method>publickey</authentication_method> > </ssh> > </action> But I got a : < <fault> < <reason>Operation Failed</reason> < <detail>[Cannot edit Host. Power Management is enabled for Host but no Agent type selected.]</detail> < </fault> In engine.log: 2016-04-25 17:51:50,837 INFO [org.ovirt.engine.core.bll.aaa.LoginUserCommand] (default task-27) [] Running command: LoginUserCommand internal: false. 2016-04-25 17:51:50,841 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-27) [] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: User XXXX logged in. 2016-04-25 17:51:52,127 WARN [org.ovirt.engine.core.bll.hostdeploy.UpdateVdsCommand] (default task-23) [173941f5] CanDoAction of action 'UpdateVds' failed for user XXXXX.

When I'm using the web UI, the reinstallation works fine. I'm using ovirt-engine 3.6.5.3 But the agent was set when I created the host, the GUI don't ask for power management informations when reinstalling the hosts and when I look the the rsdl ( at https://ovirt/api?rsdl), the agent type was not required. <link href="/api/hosts/{host:id}/install" rel="install"> <description> install vdsm and other packages required to get the host ready to be used in the engine </description> <request> <http_method>POST</http_method> <headers> <header required="false"> <name>Correlation-Id</name> <value>any string</value> </header> <header required="true"> <name>Content-Type</name> <value>application/xml|json</value> </header> </headers> <url> <parameters_set> <parameter required="false" type="xs:boolean" context="matrix"> <name>async</name> <value>true|false</value> </parameter> </parameters_set> </url> <body> <type>Action</type> ... <parameters_set> <description> install vdsm and other packages required to get the host ready to be used in the engine providing the ssh password </description> <parameter required="false" type="xs:int"> <name>action.ssh.port</name> </parameter> <parameter required="false" type="xs:string"> <name>action.ssh.fingerprint</name> </parameter> <parameter required="false" type="xs:string"> <name>action.ssh.authentication_method</name> </parameter> <parameter required="false" type="xs:string"> <name>action.ssh.user.user_name</name> </parameter> <parameter required="false" type="xs:string"> <name>action.ssh.user.password</name> </parameter> <parameter required="false" type="xs:string"> <name>action.image</name> </parameter> <parameter required="false" type="xs:boolean"> <name>action.host.override_iptables</name> </parameter> <parameter required="false" type="xs:boolean"> <name>action.async</name> </parameter> <parameter required="false" type="xs:long"> <name>action.grace_period.expiry</name> </parameter> </parameters_set> </body> </request> <response> <type>Action</type> </response> </link>
I believe that the problem is in the checks that the backend performs when the host is updated. It checks if power management is enabled, and then it checks if the agents are provided as part of the request, but in this case power management is enabled but no agents are provided, as they aren't being modified.
Looks more like an infra issue, as it is related to fencing.
Moving to first RC, since things should not be targeted to second one at this point.
Ondra - the patch is merged already. Should it move to MODIFIED?
Yes, this should be moved even to ON_QA as it was merged on May 10th. I somehow missed this bug :-(
