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)

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.
From the log:
2016-07-05 14:49:08 DEBUG otopi.plugins.gr_he_common.network.bridge
bridge._get_hostname_from_bridge_if:274 Network info: {'netmask':
u'255.255.255.0', 'ipaddr': u'192.168.10.194', 'gateway':
u'192.168.10.2'}
Meaning the interface ens802f1 has address 192.168.10.194

This is the result of:

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