What I'm trying to do is to launch three different GCE instances with Centos 7.4 and install on each of them the hyperconverged nodes. GCE doesn't allow to enable mac-spoofing on instance's nics so I'm unable to communicate with the engine from outside the host where it's installed. To make a nested VMs to be accessible from outside the host, GCE suggest to use a bridge network with iptables forwarding rules ( https://cloud.google.com/compute/docs/instances/enable-nested-virtualizat... ) but this is not going to work with high-availability. So I'm trying to do something impossible. @Sandro : this is a test environment. I'm learning to use oVirt in my off-work time so I'm trying to see if I can move my learning platform from a dedicated server to a cloud service. Thank you both Matteo
