<h2><a href="http://qemu.org">QEMU</a></h2>

<p> QEMU is a generic and open source machine emulator and

        virtualizer. When used as a machine emulator, QEMU can run OSes and

        programs made for one machine (e.g. an ARM board) on a different

        machine (e.g. your own PC). By using dynamic translation, it achieves

        very good performance. When used as a virtualizer, QEMU achieves near

        native performances by executing the guest code directly on the host

        CPU. QEMU supports

 virtualization when executing under the Xen hypervisor or using the

        KVM kernel module in Linux. When using KVM, QEMU can virtualize x86,

        server and embedded PowerPC, and S390 guests.</p>

<h2><a href="https://www.samba.org/samba/">Samba</a></h2>

<p>Samba is a FOSS suite that provides seamless file and print

services to SMB/CIFS clients, namely, to Microsoft Windows. Samba is

freely available, unlike other SMB/CIFS implementations, and allows

for interoperability between Linux/Unix servers and Windows-based

clients.  Samba is software that can be run on a platform other than

Microsoft Windows. For example, Samba runs on Unix, GNU/Linux, IBM

System z, Solaris, Mac OS X, and OpenVMS, among others. It is

standard on virtually all distributions of GNU/Linux and is commonly

included as a basic system service on other UNIX-based systems as

well. Samba uses the TCP/IP protocol that is installed on the host

server.</p>

<p>One of the key goals of the project is to remove barriers to

interoperability. Samba is a software package that gives network

administrators flexibility and freedom in setup, configuration, choice

of systems, and equipment. Samba is released under the GPL.</p>
