Hi Grant,

First of all thanks a lot for guiding me.

To conclude if i install CentOS 5.6 directly on my hard drive my question is should i install it in parallel with windows on hard drive or remove windows completely before this installation ???

You can run CentOS in a dual boot configuration with Windows on the same drive. You may want to use a Partition Manager (or gparted) disk to resize the Windows partition before you install CentOS though. I don't remember CentOS having that ability on install.
But the problem is my laptop is i5 and i dont think Centos for i5 isÂreleasedÂyet so i will have to go through other options

I don't think there would be any problem having CentOS on a Core i5. The i5 is not really THAT different to the CPUs that came before it. XCP is based on CentOS as well so you're really getting similar operating system either way you go.
1. I could get the swap hard drive thing you are telling. (Sorry if my questions are too silly)

If this is a laptop you might want to invest in an external USB drive. Change your BIOS so it will boot from it and install onto that. You could leave the Windows alone. When you want to run XCP or CentOS with Xen just plug in the USB drive and reboot.

2. ÂIf i directly install XCP on my hard drive (removing windows as xcp does not supportÂparallelÂOS - correct me if i am wrong) than can i run windows virtually on it through any other way ????

You can but beware that Xen and XCP are really designed for server virtualization and don't provide as much in the way of GUI virtualizing. However, you could install Windows in one of the VMs and use VNC to connect to it from the CentOS Desktop. XCP doesn't really have a Desktop like CentOS.

I've written a bunch of tutorials that illustrate step by step how to use CentOS/xen and create VMs. I'm currently spending a lot of time with XCP and will be writing XCP equivalents but sadly my entire site is down currently. It will be back up later.

ÂÂ Not sure if I'm following but you generally can't install a Hypervisor inside another Hypervisor ie. no Xen inside of VMWare. Also XCP is designed as a product so you install it from the install disk on bare hardware. The standard Xen Hypervisor can be installed in a Linux Distrobution from packages but even then it's good to choose your Linux distribution wisely as there's a bit of strategy to it. We recently had a thread about the best OS for Dom0 (the Control Domain) in this mailinglist.

My recommendation, get a machine (or swap drive) that you don't use for anything else and install XCP on it if that's what you want to run. If you're thinking of straight Xen then install CentOS 5.6 on it which comes with Xen.

So first of all i need toÂinstallÂXEN and understand its basics.

I think i should install XEN directly on my hard drive in my laptop and install my windows 7 in VM and may be linux on other VM.

But i just wanna to know if there is any possibility ofÂinstallingÂXENÂvirtuallyÂin VMware in windows and working on it???

Also i want to know will i need server ofr i can directly install Xen CloudÂPlatformÂin other VM directly on XEN hyperviser ????

Thanks a lot for help in advance......
