Ciao Simone,

thank you for your answer.

My lab is a nested environmet. I installed ovirt on bare metal with the
engine on another machine. On this setup i have 6 VMs:

- 172.16.1.1  pfSense as firewall/gateway
- 172.16.1.10  a windows 2016 used as network guest
- 172.16.1.12  a nethserver installation as DNS server ( also on
172.16.2.12 )
- the three ovirt-nodes as i described on my e-mail

All the machines are pingable, only the engine inside host 1 is unreachable
and can ping only host1.


Cheers

Matteo
