Description Marina Kalinin 2015-12-01 22:35:47 UTC

Description of problem:
Cannot add RHEL 7.2 host to RHEV-M 3.6 beta1.
Host becomes non operational.
The error in the engine.log:
~~~
Message: Host rhevh-19 does not comply with the cluster Default emulated machines. The current cluster compatibility level supports [pc-i440fx-rhel7.2.0, pseries-rhel7.2.0] and the host emulated machines are pc-i440fx-rhel7.1.0,rhel6.3.0,q35,rhel6.1.0,rhel6.6.0,rhel6.2.0,pc,pc-q35-rhel7.1.0,pc-q35-rhel7.0.0,rhel6.4.0,rhel6.0.0,rhel6.5.0,pc-i440fx-rhel7.0.0.
~~~

Version-Release number of selected component (if applicable):
rhevm-3.6.0.3-0.1.el6.noarch

host:
vdsm-4.17.10.1-0.el7ev.noarch
Red Hat Enterprise Linux Server release 7.2 (Maipo)

How reproducible:
100% ?

Steps to Reproduce:
1. Run hosted-engine -- deploy and choose to install rhevm from pxe.
2. Install rhevm os from pxe and then setup the engine. (engine-setup succeeded)
3.

Actual results:
Cannot continue with hosted-engine installation since the host is non-operational.

Expected results:
The setup should detected the correct settings from the host and create the cluster with appropriate settings.

Additional info:
Workaround: modify ClusterEmulatedMachines config value.

Original, default value:
~~~
# engine-config -g ClusterEmulatedMachines
ClusterEmulatedMachines: pc-i440fx-rhel7.2.0,pseries-rhel7.2.0 version: 3.6
ClusterEmulatedMachines: rhel6.5.0,pseries version: 3.5
ClusterEmulatedMachines: rhel6.5.0,pseries version: 3.4
ClusterEmulatedMachines: rhel6.5.0 version: 3.3
ClusterEmulatedMachines: rhel6.4.0 version: 3.2
ClusterEmulatedMachines: rhel6.3.0 version: 3.1
ClusterEmulatedMachines: rhel6.2.0 version: 3.0
~~~
New value:
~~~
# engine-config -s ClusterEmulatedMachines=pc-i440fx-rhel7.2.0,pseries-rhel7.2.0,pc-i440fx-rhel7.1.0
~~~

Also: I do not know where those values are coming from, but this host was installed with RHEL7.1 and then upgraded to 7.2.
