Sounds like a general NFS issue, nothing specific to oVirt. You might want to use normal debugging means - tcpdump, strace, google :-), etc. I think your last error is because you need the portmapper port (111) open. You should see this easily with tcpdump or strace. Also please note that it's not considered a good idea to use one of the hosts as an nfs server, although some people happily do that.
