Those machines are all CentOS 7.2 minimal installs. The only adaptation I do is installing vim, removing postfix and installing exim, removing firewalld and installing iptables-service. Then I add the oVirt repos (3.6 and 3.6-snapshot) and deploy the host. But checking lsof shows that 'ovirt-ha-agent --no-daemon' has access to the config file (and the one ending with ~): # lsof | grep 'hosted-engine.conf~' ovirt-ha- 193446 vdsm 351u REG 253,0 1021 135070683 /etc/ovirt-hosted-engine/hosted-engine.conf~
