7:24 p.m.
make sure nfs-lock,nfs-server and rpcbind is running
run rpcinfo -p and make sure ports on the firewall are allowed. Looks like
you are using firewalld not plain iptables. Host and client firewall
settings.
make sure you have the following in your /etc/exports file;
(rw,sync,no_subtree_check,all_squash,anonuid=36,anongid=36)
restart services and check showmount -e from client end.
Go grab the nfscheck.py file from ovirt's github directory and run it. It
will check your nfs mounts.

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. See also:
