Hi, a small question..

I'm trying to convert a .img from a xen system to a xva for my XCP system.

I did the following -> 

Somebody send me a local copy of the .img including all the needed files (kernel/config).

I eddited the xen.conf to point to the correct locations of my files it now looks like this:

# Kernel image file.

kernel = "/home/peter/xcp-convert/centos-5.0-x86_64-build-A/kernel/boot/vmlinuz-2.6.18-xen"

ramdisk = "/home/peter/xcp-convert/centos-5.0-x86_64-build-A/kernel/boot/initrd-2.6-xen.img"

# Initial memory allocation (in megabytes) for the new domain.

memory = 512

#----------------------------------------------------------------------------

# Define the disk devices you want the domain to have access to, and

# what you want them accessible as.

# Each disk entry is of the form phy:UNAME,DEV,MODE

# where UNAME is the device, DEV is the device name the domain will see,

# and MODE is r for read-only, w for read-write.

#

disk = [ 'file:/home/peter/xcp-convert/2.1-centos-5.0-x86_64-build-A/disks/disk.img,sda1,w','file:/home/peter/xcp-convert/centos-5.0-x86_64-build-A/disks/swap.img,sda2,w' ]

# Sets runlevel.

extra = "3"

# A name for your domain. All domains must have different names.

name = "centos-5.0-x86_64-build-A"

# Number of network interfaces. Default is 1.

nics=1

Then i runned the script, at it seemed to work:

~/Scripts/xcp-xva-convert/xva.py --config=xen.cfg --filename=converted.xva

After  a installation, and a succesfull import (+ copy like the echo told me to) i'm not able to start it: 

[root@box 80edf9c0-f0c3-11df-afb8-002185fade1c]# xe vm-start vm=centos-5.0-x86_64-build-A 

Error code: WARNING: /dev/xvda is not a disk image

Error parameters: Traceback (most recent call last):,   File "/usr/bin/pygrub", line 746, in ?,     raise RuntimeError, "Unable to find partition containing kernel", RuntimeError: Unable to find partition containing kernel, 

[root@box 80edf9c0-f0c3-11df-afb8-002185fade1c]# 

I asked this on the normal mailing list but they pointed me to this direction.

Hope you can help me, thanks,

Peter
