Based on this description …

A few VMs on Linux server machine and each using Internal IP which wanna each VM service accessible from outside via one public IP.

The solution is to set up the linux server (running the hypervisor) to use iptables, and then configure iptables to forward connection requests to specific ports on the external IP through to some port on the appropriate internal IP.
