Re: [Xen-users] Convert physical server to VM

["Dan VerWeire" <dverweire@xxxxxxxxx>]

Jordi,

Right now I am attempting the following procedure to move a Windows 2000 Server to a virtual machine:

Create logical volume on Xen server
Run 'nc -l -p 999 > /dev/xendisks/myserverdisk' on Xen server
Boot windows machine using Linux bootable CD.
Run 'dd if=/dev/hda bs=1M | nc 192.168.100.13 999' on Linux bootable CD
Then wait

So far this method is not working for me as I believe there is something wrong with the hard drive I am reading from. I receive hda IO errors when I reach around 5gigs transferred. 

I am also looking into using partimage to create an image of the drive, transfer that to my Xen server and put the image into my logical volume.

Hope this helps in some way.

Regards,

Dan

¿Anyone has some experience with this method into a production
environment? I'm looking for a tool/method to do it.
