the log says the mount command timed-out:
/usr/bin/sudo -n /usr/bin/mount -t nfs -o
soft,nosharecache,timeo=600,retrans=6,nfsvers=3
patascoy.udistritaloas.edu.co:/oVirt/vms

18:04:29,443::storageServer::211::Storage.StorageServer.MountConnection::(connect)
Mount failed: (32, ';mount.nfs: Connection timed out\n')
In the host with the NFS Data Storage add the following rules in Iptables:

-A INPUT -p tcp --dport 2049 -j ACCEPT
-A INPUT -p udp --dport 2049 -j ACCEPT
-A INPUT -p tcp --dport 111 -j ACCEPT
-A INPUT -p udp --dport 111 -j ACCEPT
