I am using ovirt and have two VMs. The VMs are fedora 20. I want to use one VM as a DNS server and One as a Web server. I can ping and ssh between the VMs. But i Cannot communicaton on ports 53 or port 80. When i use netcat I get no route to host. IPtables is turned off and selinux is disabled so nothing is blocked. The VMs are also on the the same VLAN, have the same gateway and netmask. I am new to Ovirt networking so any help would be appreicaited.

thanks in advanced

I'm guessing that your two VMs aren't on the same subnet. Since DNS relies on the Universal Datagram Protocol, and UDP cannot traverse gateways without intentionally configuring the gateways (or some other forwarding system) to allow it, any client contacting the DNS system will need to be on the same subnet. If there's no route discovered between the systems, that's probably your problem.

If that's not the issue, can you post the ifconfig information from each guest domain and the virtual bridge information from the host?
