Hello Friends of oVirt, I'd setup a oVirt enviroment (hosted-engine) behind a proxy. But I can't add any additional Host to my Cluster. I'm phase of testing (SELinux Permissive, No firewall) All the machines are CentOS 7.1 When I try to add a Host, the operation it's OK, but don't see the Data Master Storage and the operation at the ends fails, and the additional host it's Non Operational. FQDN Engine: ovirt.udistritaloas.edu.co FQDN Host with the Host-Engine and with the Data Master Storage: patascoy.udistritaloas.edu.co FQDN Additional host: sotara.udistritaloas.edu.co This is the resume: 2015-Apr-13, 17:08 Failed to connect Host Sotara to Storage Pool OAS 2015-Apr-13, 17:08 Host Sotara cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center OAS.
