I once saw an application that seperates your application in a seperate environment; has a virtual memory and registry and filesystem. It is like application isolation, but would allow any operation that I can do such as Installing applications and having administrator rights. I am not talkin about VirtualBox or other software. But I cannot find what I want. Any software offer would be appreciated.
What you describe reminds me of VMware ThinApp. It seems to be quite expensive though.
SpoonStudio (Link) seems like what you're after, it was formerly called Xenocode.

In the recent times, I tend to set-up and configure more and more VMs daily with very similar or the very same configuration, and due to the time consumption caused by that, I'm looking for a way to automate the whole process.
I have started looking around and I have found Vagrant which could be a very good starting point.
I would like to create a custom build of a VMWare VM ( vagrant box if not mistaken ), and I would like to use that box as my base and deploy it on my servers.
The trouble starts here:
On my servers I use VMWare vSphere and I see that Vagrant can support it via an external plugin, but, as I read along, I see that vSphere only supports VMs created from template or cloned from an existing one.
Is there any change to run my VMWare Workstation boxes with it ?
Also, I would be very grateful if you could provide me with some more info on the same matter using other ( maybe better suited ) solutions.
I know there are also Chef and Puppet, but are they maybe an overkill for my needs ?Thank you for your time and help,Best regards.
Have you looked into Ansible? http://www.ansible.com/home
There is an opensource one available it is extremly easy to use. Might be what you're looking for.
I would love to have an idea on how to automatically install a Windows XP virtual machine on Virtualbox/VmWare. Is this feasable via a programming language, for example ? Or maybe an automated script ? I need this to avoid manual installation each time one of my VMs crashes.
I am not asking for a full program that does this, but I just needs technical hints on how to do this, then I will perform your suggestions myself.
Yes it's possible.
Can't you just make a snapshot to when the VM is working, or at least a "Clean Install" snapshot that saves having to reinstall your OS and common applications every time?
Yes, it is possible to do this via script. Actually, all IaaS cloud companies now try to do the deployment of VMs (and also physical servers) via automation. First of all, it's cheap a quick. And there is little human factor in it.
Not sure about VirtualBox, but if it works with VMware, KVM etc., there is no reason it shouldn't with VB.
As for the script itself, there are big money in this, so finding something may prove difficult. Try to check openStack, AFAIK it should be open source.
I am talking out of the box without configuring anything. I would like to be able to get basic stuff like application response time.
There are some basic metrics in the JBoss AS 7.1.0.CR1b and greater web console.
There is not a tool out of the box without any configuration that you can use that I know of. You can use JON with some basic configuration set up. Other profiles also require some setting up front. But if your organization uses JBoss heavily then JON may be the route you want to take.
You can utilize JON for monitoring, provisioning, managing upgrades, deploying applications, etc for all JBoss instances in your domain. You can also monitor the server it's running on (CPU spikes, memory usage, disk space, etc). JON 3.0 is out now so I would recommend starting with that. The community forum is located here.
Other options include using VisualVM or JProfiler or DynaTrace like tools.
I had this thought experiment of installing an OS on a php server over http.
So, what I am asking: Would it be possible to build a VM player (using the server's resources) from a server language like perl, php, or python? Or is my understanding of servers and security lacking in a way that would show this to be impossible?
It's not as outlandish as you might think.
UeberHacker Fabrice Bellard (the guy who created QEMU, among many other notable achievements) recently did precisely that. He created a VM in Javascript. That runs a virtual Linux system in your Web browser:

When deploying a ready to use erlang application I don't want the user to
Find the right erl release on the
internet.
Install the erl vm
unzip and decide a location for the beam files (with the application)
read a readme
modify anything that even looks like a config file
I have a couple of ideas of what could be a way but I would like to get some input.
SAE (stand-alone Erlang) used to be a pretty good solution for situations like you describe, but that no longer seems to be maintained.
Although I've never used it myself, CEAN seems like it might come close to what you want: it offers a self-extracting installer (though not for Windows at present) and the option to deliver a customized minimal Erlang framework.
There is also Erlware.
At our core we host public
repositories containing reliable
Erlang OTP-compliant applications. Our
repositories enable developers to use
software written by the Erlang
community and to publish and
distribute their own software.
It's more backend orient though, so not a complete solution.
The reltool application first released with Erlang R13B02 is aimed at solving this issue. Note that it is currently a beta release (version 0.5).
