Uploading an image with qcow2 compat 1.1 is unsupported for storage format type V3
Hi all, how can I get informations about supported formats with the image upload feature ? All my domain storages are v3, does it exist v4? If yes, how can I upgrade them to a superior format? Do I need to convert my non compatible 1.1 qcow2 appliance to an other format? This is what I found : https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/htm...

Actually, supported QCOW formats are derived from the ovirt storage versions (V3, etc..) of a DC, and the upload flow just restricts the user so the supplied image that is being uploaded will be supported in the DC that owns the target storage domain. So basically, the DC specifies the supported formats, not the upload feature.

V4 is about to be introduced (targeted to 4.1), and it will support QCOW2 version 1.1. You will be able to upgrade your DCs to this version easily when it will be available.

Exist in upstream. You can install a development version if you like to play with this on testing environment.

If you don't care about backward compatibility in 4.0, you can configure the system to use format 1.1 by like this: [irs] # Recent qemu-img supports two incompatible qcow2 versions. We use # 0.10 format by default so hosts with older qemu can consume images # created by newer versions. See https://bugzilla.redhat.com/1139707 # (supported versions: 0.10, 1.1) qcow2_compat = 1.1 Note that this will break image upload, because engine allows only 0.10 images. We don't have similar configuration in engine.
V4 is about to be introduced (targeted to 4.1), and it will support QCOW2 version 1.1. You will be able to upgrade your DCs to this version easily when it will be available.

Yes, you can convert 1.1 image to 0.10 using: qemu-img amend -o compat=1.1 /path/to/image In 4.1, when using storage domain version 4: - new disk will use format 1.1 - you will be able to upload both 0.10 and 1.1 images - you will be able to convert old images from 0.10 to 1.1 Nir
