问题
I want to configure oVirt in Vultr bare metal server. But I don't know how to configure Engine VM FQDN. It always tell me The address proposed for this host does not resolves locally. There is error message:
And I've already configure my /etc/hosts file.
Here is my /etc/hosts code:
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
127.0.0.1 guest
::1 guest
127.0.0.1 VTest
::1 VTest
149.28.103.174 ovirt
127.0.0.2 test
I've tried FQDN guest,localhost,ovirt,localhost.localdomain. These all are not work. 149.28.103.174 is my public IP.

@smith cruise If you dont have you own DNS Servers you must enter in DNS entries in the /etc/host file on the oVirt node for the oVirt engine and oVirt node. Example
192.168.1.10 ovirt-engine-02.labl.local ovirt-engine-02
192.168.1.11 ovirt-node-02.labl.local ovirt-node-02

Red Hat RHEV documentation is saying:
Red Hat strongly recommends using DNS instead of the /etc/hosts file for name resolution. Using a hosts file typically requires more work and has a greater chance for errors.
ovirt is not a FQDN. engine.ovirt.yourdomain.com is an example for a fully qualified domain name.
So the answer is: use DNS to define your hostnames of the oVirt components and provide the engine setup with a FQDN not just a hostname.
In case you can't use DNS, you can add the information to the /etc/hosts file on every oVirt node. It should contain the ip and name of the engine, all nodes and possible addional services. See the example.
# centos 7 localhost config
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
# engine and nodes
192.168.30.3 engine.infra.yourdomain.com
192.168.30.10 node01.infra.yourdomain.com
192.168.30.11 node02.infra.yourdomain.com
192.168.30.12 node03.infra.yourdomain.com
192.168.30.13 node04.infra.yourdomain.com
192.168.30.14 node05.infra.yourdomain.com
192.168.30.15 node06.infra.yourdomain.com
# additional services
192.168.30.9 cinder.infra.yourdomain.com
There are two sources of documentation. The oVirt manuals are sometimes a bit sparse. The Red Hat RHEV manuals are much richer, although Red Hat biased.

I was running into the same issue myself. Eventually, I used a (sub) domain that was not pointing to my IP or entered in my Hosts and it that worked.
