Meaning the interface ens802f1 has address 192.168.10.194

This is the result of:

python -c 'import socket; print(socket.gethostbyaddr("192.168.10.194"));'

Please run above python command and see for yourself.

Perhaps you have other means it uses for name resolution.

Check /etc/nsswitch.conf, getent, mdns, /etc/hosts, etc.

[ovirt-users] hosted-Engine setup: hostname 'node01.example.com' doesn't uniquely match the interface selected for the management bridge

2016-07-05 Thread mots 
Hello,

I'm trying to install Ovirt 4 on a new set of hosts. During "hosted-engine 
--deploy" I get the following error: (personal information is replaced with 
generic placeholders)

[ INFO  ] Stage: Setup validation
[ ERROR ] Failed to execute stage 'Setup validation': hostname 
'node01.example.com' doesn't uniquely match the interface 'ens802f1' selected 
for the management bridge; it matches also interface with IP 
set(['192.168.99.10']). Please make sure that the hostname got from the 
interface for the management network resolves only there.

That IP "192.168.99.10" doesn't resolve to anything, because I haven't added it 
to the DNS server. It's also not in /etc/hosts.
It's just the IP for the storage network that doesn't use DNS at all.

Why does the setup script think that my hostname resolves to 192.168.99.10?
