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
