Fedora Cloud - Which virtualisation software?

Hello, i' m planning to use Fedora 24 Cloud in a Qcow2-formatted image for use with OpenStack. I would like to hear some suggestions on the questions below:

1)Which software do you suggest for virtualisation: The default Gnome Boxes, Virt-machine from Red Hat, VirtualBox from Oracle, or something different like Xen etc? In terms of efficiency.

2)Can i install mobile OS images? Android i.e. to make it less resources hungry, or any Linux distribution in basic command line installation would do the job?

3)Finally i would like to know, when i use the virtual OS to connect to the internet for the example, the server to which i' m connecting, does read an IP, and if yes, which? My host computer's one?

I have used Fedora 24 Cloud with kvm as hypervisor read some people used fine with Xen for performance, if you want to build your own images Virt-manager and kvm was my choice and works fine. Have used Android for x86 with no issues with virt-manager and using qemu-system-arm to use some arm images including Fedora. If you want a lest hungry resource Linux Distro will recommend Alpine Linux, but read it first have there are differences. Also check using Docker on OpenStack.

KVM virtualization is used on Xen is used by Amazon and Rackspace.

I'm not quite sure I understand some of the basics of your question here. If you are using OpenStack, the KVM hypervisor is a good choice — but then _OpenStack_ is your management software. You don't need Boxes, or virt-manager, or anything like that. And, where exactly do you want to install mobile OS images, and what particularly do you mean by "resource hungry"?

@aeperezt Thank you for the contribution.

@mattdm Hi, i know that the structure of my question could confuse some. Now when i talk about "resource hungry" i mean for example to create for example 20+ virtualized apps mainly rather full OS, and run them all together. With classic methods, current RAM/CPU cores won't be enough. So probably i will go with KVM or LXC or Xen paravirtualize. Thanks for clarifying about OpenStack. I'm new to this and i thought i need a cloud to use it,but it seems it work;s the opposite way.

OpenStack is software for creating an infrastructure-as-a-service cloud for yourself. This is probably overkill for the use-case you describe in your comment

i mean for example to create for example 20+ virtualized apps mainly rather full OS, and run them all together.

Fedora includes a _hypervisor_, KVM, which is able to run fullly-virtualized operating systems. Both virt-manager and GNOME Boxes are GUI managers for this, but you don't strictly need them. If you do want virtualization, I _do_ suggest running KVM rather than VirtualBox or VMWare -- it's fully open-source and in the upstream Linux kernel.

But, for your case, I don't think you really want virtualization at all. You should instead look at OCI-style containers, like Docker, possibly orchestrated with Kubernetes.

For this, you would install Fedora Atomic Host -- either on a VM or as your server's base operating system, and then package your applications into containers with Docker. Take a look at this guide for more information.

Virtual Box from oracle is your answer trust me i tried most of the Virtualization programmes out there non came close to oracle Virtual Box Virtual Box is a powerful x86 and AMD64/Intel64 virtualization product for enterprise as well as home use. Not only is VirtualBox an extremely feature rich, high performance product for enterprise customers, it is also the only professional solution that is freely available as Open Source Software most programmes will run slow once you set them but not Oracle VirtualBox you get a fast efficient running machine beside you can modify you setting for your machine in terms of space, ram,etc network problems rarely occurs in Virtual Box but even if it does its an easy fix
I hop this helps you wish you the best of luck

Virtual Box is a free ware not Open Source

That is the introduction on oracle's web site i didnt invent it but feel free to say otherwise :)

I have red thoroughly about Oracle's software, but i have decided that it doesn't suit for my needs, even if it looks like an around the clock program.
