Description Andre Naehring 2012-02-20 12:25:11 UTC

Description of problem:
Using virt-clone or the virt-manager changes the image format of the copied image file to raw if the source (and destination) is a qcow2 file.


Version-ReleName        : 

python-virtinst
Version     : 0.600.1
Release     : 1.fc16
Architecture: noarch
ase number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Create a VM with a qcow2-based image file
2. use virt-clone --auto-clone
3. try to start the clone, the harddisk is not bootable 
  
Actual results:
VM cannot boot.

Expected results:
The VM should boot.

Additional info:
changing the image-file-format back to qcow2 the VM will boot.

Comment 1 Cole Robinson 2012-02-20 18:03:08 UTC

Hmm well that's no good. Can you provide the output of virt-clone with the --debug flag when reproducing?

Comment 2 Andre Naehring 2012-02-21 06:46:36 UTC

Here is the complete output with some additional information:

I was to fast here. When setting the "type=" to "qcow2" the vm is able to boot. So while cloning, the original image type is used to create the destination but the XML definition is writing "raw" instead of the correct image type.

Great, thanks for the info. Fixed upstream now:
