Hello, 
I'm trying to add a 2nd vdsm host in an existing working cluster and host (host 1). It seems all the service are running (vdsmd, nfs, and network) on host 2. 
When I create the new host, it begins installing packages, but then get the following error: 
"Host Host-2 installation failed. Command returned failure code 1 during SSH session [user@host]".
I can't seem to find the solution on google. I can ssh into host 2 from the ovirt engine. I've tried it with iptables on and iptables off. 
Any help would be greatly appreciated. 
Many thanks,
Drew
