Bharat - Can you supply the following grep -i processor /proc/cpuinfo free -m gluster volume info
From each node. Maybe post to pastebin or something so its easier to read

Hi,
I've reinstalled Centos minimal on 3 hosts. Configured replica 3 gluster storage for engine & data. Configured dns entry in /etc/hosts for all three host and ovirt engine also. *yum install ovirt-engine-appliance* *hosted-engine --deploy*
Choose glusterfs storage for engine. Installation failed at last step "This system is not reliable".
My host have low memory & processor so don't know it might be the issue.
Please help.

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.
