Package uploaded to -proposed, awaiting SRU team approval. ** Description changed:
- I tried the cloning feature of virt-manager. First I created a VM with - qcow2 disk and installed Ubuntu on it. Then I shutdown the VM and - created a clone of it. The clone was successfully created, but the - configuration of the disk is invalid. The disk type in the cloned VM is - raw, not qcow2. The actual format of the cloned disk image is qcow2, - only the config is wrong. After changing the type of the disk back to - qcow2, the cloned VM can see the disk just fine. + SRU: + + [Impact] + Precise users aren't able to use the virt-clone command, or the clone functionnality in virt-manager to create successful clones of VMs using qcow2 images, as the disk image format is not being transferred properly to the clone. + + [Test Case] + 1- Create VM with qcow2 disks + 2- Clone VM with virt-manager + 3- Inspect clone xml file to make sure qcow2 image format is set correctly + + [Regression Potential] + This change is limited to the clone code path. If something breaks, it will be VM cloning. + + + I tried the cloning feature of virt-manager. First I created a VM with qcow2 disk and installed Ubuntu on it.
