I installed 2 Ovirt 4.2.2 servers and installed the hosted-engine-appliance on one of them. I used the web interface to add storage domains and add the second host but suddenly I lost connection to the hosted-engine.
I tried rebooting the host but the reboot just hangs. The server is still pingable but the server console is black. I eventually did a hard reset of the server. Currently the host is back up-and-running but the hosted-engine seems to be unable to start.
I am getting lots of e-mails
