Hi, I've reinstall Centos7 Minimal on all three hosts. Installed Ovirt self hosted ova 4.1 on test1.localdomain. After installation completed, I got an error like engine vm is unreachable. I am able to ping engine from both IP and FQDN but unable to access it in browser. When I check engine VM status I got an error "Failed to connect to broker". I've enclosed engine-vm config snap and Error snap for more details. Kind help to resolve it.

I can't. I've destroyed that VM and clean all files. Now I am trying to reinstall new engine VM.

Can you ping the VM when it comes up?

I am not using any DNS server. I have made entries in /etc/hosts for all Nodes and for engine VM also.

Bharat,
Are you using DNS for host names or /etc/hosts
I personally place the engines hostname with ip address in /etc/hosts on all the hypervisors in case my DNS services go down. I also put the hypervisors in /etc/hosts too
Hope this helps.

Hi Charles & Donny,
Thank you so much.
@Donny my 3rd node's IP is 192.168.100.17(Mentioned wrong in above mail). I was trying to install ovirt ova on test2.localdomain. I've cleared all the steps and at last I got a message like "Engine is still unreachable". Kindly help me to troubleshoot it.
@Ykaul How can I register myself in mailing list?
