Hello,

I am trying to migrate paravirtualized VM from xen legacy (running debian with xen 3.2) to XCP VM.

VMs are debian lenny x64. Their disks are LVM volumes, with each volume used as a partition, like this:

disk        = [
                  'phy:/dev/vm_volumes/nyctalus10-swap,sda1,w',
                  'phy:/dev/vm_volumes/nyctalus10-disk,sda2,w',
              ]


The process I'm trying is (from http://forums.citrix.com/thread.jspa?threadID=242336&tstart=0):

* Generate a raw image of the volume with qemu-img
* Create the new VM in XCP: I create the new VM from "CentOs 5.4 x64" template (I don't use the debian template because is for 32 bits)
* Import the raw image to the VDI with xe vdi-import

        The problem I have is that when I try to run the VM I get:

[root@felis315 ~]# xe vm-start uuid=3dc0b4df-b0e8-c665-1a28-d2654281faf3
The bootloader returned an error
vm: 3dc0b4df-b0e8-c665-1a28-d2654281faf3 (nyctalus10)
msg: Error from bootloader: Failed to parse the output of bootloader: ()

        Any idea? Is there any other way to migrate VMs?
