Yeah! Sure!

 Today I'm doing this work manually... I mean, to copy a VM from open source
Xen to the XenServer I do:

1- stop the VM on my debian dom0;
2- mount its root file system under /mnt/source;
3- export it via NFS;
4- At the XenServer, I boot the sysrescuecd (a live system);
5- fdisk the /dev/sda;
6- create the LVM volumes;
7- mount /dev/vg01/root under /mnt/target;
8- mount /dev/sda1 under /mnt/target/boot;
9- mount the debian dom0 nfs server under /mnt/source;
10- cp /mnt/source/* /mnt/target/
11- edit the /etc/fstab and the grub's menu;
12- shutdown the VM;
13- Convert it from HVM to PVM;
14- start the VM;

Thanks,
Thiago
