Hello Florian,
there is no problem to reslove the FQDN
[nolden at oVirtNode01 ~]$ nslookup oVirtEngine.com
Server: 192.168.122.1
Address: 192.168.122.1#53
Name: oVirtEngine.com
Address: 192.168.122.201
The '/etc/hosts' file of each host is configured to resolve the name.
I tried it with stopped firewall,
[nolden at oVirtNode01 ~]$ sudo systemctl stop firewalld
[nolden at oVirtNode01 ~]$ sudo systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled;
vendor preset: enabled)
Active: inactive (dead) since Di 2016-11-08 09:10:46 CET; 3s ago
Process: 724 ExecStart=/usr/sbin/firewalld --nofork --nopid
$FIREWALLD_ARGS (code=exited, status=0/SUCCESS)
Main PID: 724 (code=exited, status=0/SUCCESS)
but i got the same error!
