Exist in upstream. You can install a development version if you like to play with this on testing environment. > If yes, how can I upgrade >> them to a superior format? 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. > >> >> Do I need to convert my non compatible 1.1 qcow2 appliance to an other >> format? 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 >> >> This is what I found : >> https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Virtualization_Deployment_and_Administration_Guide/sect-Using_qemu_img-Supported_qemu_img_formats.html >> >> >> Thank you >> >> >> -- >> Nathanaël Blanchet >> >> Supervision réseau >> Pôle Infrastrutures Informatiques >> 227 avenue Professeur-Jean-Louis-Viala >> 34193 MONTPELLIER CEDEX 5 >> Tél. 33 (0)4 67 54 84 55 >> Fax 33 (0)4 67 54 84 14 >> [email protected] >> >> _______________________________________________ >> Users mailing list >> [email protected] >> http://lists.ovirt.org/mailman/listinfo/users > > > > _______________________________________________ > Users mailing list > [email protected] > http://lists.ovirt.org/mailman/listinfo/users > _______________________________________________ Users mailing list [email protected] http://lists.ovirt.org/mailman/listinfo/users
