With a lot of Virtualization technologies I m bit confused which one to opt for .

Following are the few choices in front of me.
1) Virtual Box
2) Oracle VM
3) VMWARE

Can any one please tell me the best technology in terms of value for money .

(I m currently working on Oracle VM have few questions about it.

What is Xen technology (I think OVM using that correct me if i m wrong)?
Is it stable?)
Being free is it as powerful as Virtual Box and VMWARE?
Why should i go for it?
Is this forum answers any query related to OVM.

You seem to be asking about virtualization not visualization. You may get more feedback if you change the title as such.

The free ones are likely to be better value for money than the ones you need to pay for.

Evo2.

You are right but how would i change the topic name.
I wouldn't mind to pay if they are trustworthy .

Yea, oracle-vm is a repackaged Xen.

There are free, as in beer, versions of VMware, as well as free, as in speech, versions of Xen, KVM, etc.
Likewise there are pay versions of VMware (obviously), and pay versions of Xen, KVM, etc. In the case of Xen and KVM, I believe there are multiple companies who sell pay versions of them.

The difference between the free and pay versions is really support. Many of the pay versions have extra features, but the main difference is you have someone to call at 2AM.

Which is more powerful has nothing to do with free or not. Xen, KVM and VMWare fans can all come up with perfectly legitimate and reproducible cases where their favored system is significantly faster. Real world use tends to show that while one may be faster than the other, you probably won't notice a performance difference.

If you're only hosting linux boxes, the container based systems OpenVZ and Linux-VServer should be faster than KVM, Xen, VMWare, etc. Wikipedia is your friend here, it will do a better job of describing how they work.

As far as best value for the money "value/money".... well that's the wrong question to ask. Look at the value for the money and time. "value/(money+time)"

A free system that is a pain to setup and work with isn't good. A pay system that is a pain to setup and work with is even worse!

Good luck

Forgot to mention, yes Xen and KVM are stable. VMWare is also stable, but the management interface is not always (in my experience).

I don't know how the Xen and KVM GUIs are, since I gave up on them pretty quickly. I use the CLI tools, they're fine.

If you want a web-frontend to KVM and OpenVZ, proxmox is supposed to be good, but I've not tried it. There should be others for the other systems, just search around. Good luck.

it depends on what you're after - a local vmware-workstation/virtualbox style virtualization, or a full fledged cluster of hosts holding a bunch of critical VMs, using a centralised storage backend and migrating VMs between hosts according to policy.

Once you explain what you're trying to achieve, it will be easier to give you the correct solution

First you need to decide if your system is fully or partially supported. For example VMware's esxi may need more ram or a nic to be installed. Bios and CPU fully supported may also be a big decider. Tell us about the hardware maybe.

I agree that your use would need to be known.

The Sun X4170 should work fine with ESXi.
