P2V active directory (2003) to xenserver6
One of my 2003 AD has HW issues and looks like the servers is in it's final way... any day now...
I would like to convert it to xenserver Virtual machine.
would like to hear if anybody did this kind procedure successfully and how?
would like to hear reasons why I shouldn't do this on an Active Directory Domain Controller... if any...
Thanks!

Have a read here on how to P2V to Xenserver.
There are no reasons NOT to convert your AD server to a VM, makes perfect sense, ALL my DC's are running as VM's.
Just ensure that you have more than ONE DC in your domain, as always.

It is not recommended to P2V a Domain Controller. Although it has worked for some, I highly doubt you get it virtualized completely successfull this way.
What I used to do is simply shut down the machine and boot with a Clonezilla live CD and Image the servers System drive. Then I create a new VM in Xenserver using the windows 2003 server template in your case. Create the disk drive with the same or bigger size as the pyhsical system drive. Then boot the VM using the Clonezilla live CD ISO file.
Restore the image to the virtual drive and restart the system, this time booting from the disk.
This usually lets me start the VM. I then first install Xentools and reboot, then go back and remove any drivers and utilities that stem from the physical system. For example HP Network Card Management Utilites, or any System management software that do no longer apply to the virtual server.

Do not p2v an existing DC. Bring up a new server VM, run dcpromo on it, transfer any fsmo roles from the bad server to your new DC and then dcpromo down the bad DC.

Please exlain WHY?
Doing a P2V of a windows server to xen does NOT mean doing a LIVE Migration. What you describe, using clonezilla, is called "DOING A P2V"!!
I have done many a P2V of DC's using this technique, clonezilla, acronis, various other... and very rare it fails.

why not just create a new Server, and DCPROMO to promote to a DC, and Transfer the Roles?
This is much quicker and less effort than a P2V, and less risky if no risk, and Supported!
DO NOT wait for the existing server to die, get building a new Virtual Server, create a DC, transfer roles, you should be done in 60 mins!

microsoft recommends doing an offline p2v of a dc. too many moving parts when a dc is powered on. plus you don't have to worry about usn rollbacks.

I have to disagree. P2V is usually done while the system is live (in case of xenserver, by running the xenconverter utility while the system is live)
It then uses a combination of file locking and VSS (volume shadow copy) to create a consistent image of the live system, and in case of xenconverter automatically converts the system to a VHD and copies it over to Xenserver. While doing all this, it will also make the new VHD ready for operation in a VM environment. It will reset some of the system drivers to make them run on a virtualized platform, deactivate some system features not needed in a Virtual environment etc.
In case of a DC, there are so many AD operations that could happen on the DC while the Image is created, that xenconverter (or any P2V Tool for that matter) will have a hard time creating a truly consistent image. That's why I say, P2V of a DC is not recommended (not my opinion alone by the way, but official Citrix recommendation)
Doing a system virtualization by using an offline tool like Clonezilla is not real P2V.
And if you read my comment correctly, I actually state that my preferred way is to use an offline tool for DC Virtualization rather than a P2V method.
So I don't get your last sentence:
I have done many a P2V of DC's using this technique, clonezilla, acronis, various other... and very rare it fails.
It is some much easier to just build a New VM and Promote it to a DC, transfer the roles and decom the old DC. As stated there are to many moving parts in regards to replication and other recording events. By building a new machine you eliminate all possibilities of a P2V failure. Then you also need to deal with Post P2V conversions cleanup which adds to down time.
Application Servers like Files, IIS and third party apps are perfect candidates for P2V when there are no databases that are continuously being written.
When we did out SQL servers we downed the SQL service prior to P2V and announced and outage.
Would you do P2V of your Exchange or just build a new one and move the Mailboxes?

If you don't mind downtime, a P2V would be preferable. Simply stop all Exchange services before starting the P2V Process and you should be fine. You could also make sure you have an alternative MX configured (most ISP's offer a so called MX 20 record ) This will make sure emails sent to your domain are stored at your ISP in case your mail server fails and are delivered as soon as it is back online. This way no sender will receive a non delivery report when your mail server is down.
If you can't have downtime, then rebuilding a secondary mail server would be preferable as you can first reroute all incoming mail to the new one and then migrate one mailbox at the time to the new server before dismantling the old one.
