Try with 192.168.122.1 instead.

192.168.122.1 also doesn't work.

root@ubuntu:~/test1# ./client 192.168.122.1 8081
agrv[1] = 192.168.122.1

Apparently your firewall would reject connections actually.

Do you mean this one rejects the connection from VM ubuntu?
-A RH-Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited
