We have some 10 physical servers running Windows Server 2003. Now we have bought a new xen server.
I have added Windows Server 2008 R2 as host as a guest VM in xen host. Now we are planning to move the physical boxes to xen as VM. I Googled it and could see most people suggested using a P2V tool, but I am not aware of one.
Any clear ideas or steps to do the above mentioned will be really helpful.
Firstly your second sentence makes no sense at all, secondly a 5 second google search for 'xen p2v' links to lots of ways to do this, including THIS one. Try to put/some effort into things next time before coming on here, it is a site for professional sysadmins after all.
