Re: [ovirt-users] oVirt 4.2 ansible 'Add hosts' task doesn't work

Hi all, - Here is a simple architecture for my demo deployment using KVM VMs: 1) rhevm1.ab.lab -> oVirt Engine (CentOS 7.4 x86_64) 2) rhevh1.ab.lab -> oVirt Enterprise Linux Host (CentOS 7.4 x86_64) 3) rhevh2.ab.lab -> oVirt Enterprise Linux Host (CentOS 7.4 x86_64) - How to reproduce issue: 1) I installed 'ovirt-engine' successfully. 2) I tried to add 'rhevh1.ab.lab' from 'rhevm1.ab.lab' using SSH public key.

Everything was OK until I had the following error message: "Host rhevh1 installation failed. Failed to execute Ansible host-deploy role. Please check logs for more details: /var/log/ovirt-engine/host-deploy/ovirt-host-deploy- ansible-20171229144439-rhevh1.ab.lab-13b2b5c4.log." Checking log file showed the following: [root@rhevm1 tmp]# cat /var/log/ovirt-engine/host- deploy/ovirt-host-deploy-ansible-20171229144439-rhevh1.ab.lab-13b2b5c4.log 2017-12-29 14:44:40,320 p=9666 u=ovirt | [DEPRECATION WARNING]: The use of 'include' for tasks has been deprecated.

Are you sure you want to continue connecting (yes/no)? yes 192.168.150.21 | SUCCESS => { "changed": false, "ping": "pong" } 4) It seems that above ansible role is not able to deal with SSH fingerprint for the first time even if I was able to collect 'rhevh1.ab.lab' fingerprint during adding host procedures. 5) I have tried to disable this feature in ansible.cfg file: [root@rhevm1 tmp]# grep host_key_checking /etc/ansible/ansible.cfg host_key_checking = False 6) Again the same results: [root@rhevm1 tmp]# cat /var/log/ovirt-engine/host- deploy/ovirt-host-deploy-ansible-20171229145907-rhevh1.ab.lab-3e8bace0.log 2017-12-29 14:59:08,005 p=10135 u=ovirt | [DEPRECATION WARNING]: The use of 'include' for tasks has been deprecated.
