Description of problem:
I have a setup of rhevm 3.5.
added a rhel7 host. host deploy succeeded and vdsm is up
selinux is set on permissive state. yet the engine can not seem to establish connection with the host despite the fact that the host is fully reachable.
I will attach all the relevant logs

Saggi is right that it is not related to jsonrpc. Together with Ohad we investigated the issue and after capturing the traffic we can see that the host response to any network frame sent to vdsm port is ICMP type 3 code 10 which is
according to the iptables rule:
REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited
My assumption is that we do not configure iptables properly during host deploy.
