[ovirt-users] Best way to add qcow2 file to block storage domain

Hello, I have a qcow2 image file with these details with "qemu-img info" command: file format: qcow2 virtual size: 66G (70866960384 bytes) disk size: 1.5G cluster_size: 65536 Format specific information: compat: 0.10 I'm on 4.2.6 and If I try to upload as a disk from the GUI it seems it tries to upload full 66Gb, not 1.5Gb... And it goes paused after the probably transferred 1.5Gb... Also, I would like it to be qcow2 1.1 and not 0.10 I have run: qemu-img convert -O qcow2 -o compat=1.1 source.qc2 source.qc2_v3 and now I have file format: qcow2 virtual size: 66G (70866960384 bytes) disk size: 4.2G cluster_size: 65536 Format specific information: compat: 1.1 lazy refcounts: false refcount bits: 16 corrupt: false Is it expected to pass from 1.5Gb to 4.2Gb after conversion? Anyway also in 1.1 format, if I try to upload It keeps sending the whole 66Gb and now it goes in paused after about 1 minute (at rate of 60MB/s) that lets me think that once arrived at the 4.2Gb size it has problems... Any hint? Thanks, Gianluca
