If we had an option to set the initiator when adding a host, like the way you set the host password, it would be hard to have such bugs. Can you file a bug about this?

Re: [ovirt-users] HELP Upgrade hypervisors from CentOS 6.8 to CentOS 7
To resume the situation and be the most clear I can. I have : - 2 hypervisors (physical) with CentOS 6.8 : HYP1 and HYP2 - 1 oVirt manager 3.5 (physical and not hosted-engine) with CentOS 7.2 And to be able to upgrade to oVirt 3.6 or more I need to upgrade the 2 hypervisors to CentOS 7.2. So I began with HYP2, I’ve removed it from the Cluster, and installed it with CentOS 7.2, but when I wanted to join it to a new cluster as shown in the doc, HYP2 stayed always unresponsive. So I’ve restored the HYP2 to Centos 6.8, reinstalled it on the previous cluster and everything works well, but I really want to upgrade to CentOS 7.2 to be up-to-date, because I will have soonly more than two versions late.

[ovirt-users] HELP Upgrade hypervisors from CentOS 6.8 to CentOS 7
Hi, I'd like to upgrade my oVirt environment from 3.5 to 3.6 and maybe 4, actually the manager oVirt is un 3.5 version, installed on a CentOS 7.2 and the two hypervisors are installed on CentOS 6.8. I need anyway to upgrade the hosts to be able to move to 3.6. I've tried to upgrade the first host, but I had of course issues telling that it can't be possible to mix different OS in the same cluster, I've also tried to create another cluster to put this host without success. What is the best way to upgrade cleanly and safely ?
