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...
You hit
https://bugzilla.redhat.com/1627032
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
This works, but you can use amend instead of convert.
You can also upload the image as is, oVirt amend the image to use 1.1 after
the upload.
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?
The original image probaly had some compressed clusters. Converting
uncompress all clusters.
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...
Same issue
Any hint?
Update to 4.2.7, or upload using the SDK:

Nir
