[Qemu-devel] qemu-img convert (vmdk)

[Antoni Villalonga]

Hi,

Is my first email to that list ;)


I can reproduce this bug with v2.2 and v2.3. I'm not sure about the results
after testing with v2.1 (doesn't show errors but seems to be still broken).

% qemu-img convert -f raw -O vmdk -o subformat=streamOptimized 100GB_inputfile.img outputfile0.vmdk
(no shown errors/warnings/info)
% qemu-img convert -f vmdk -O qcow2 outputfile0.vmdk outputfile11.qcow2
qemu-img: error while reading sector 278528: Invalid argument

Let me know if I can provide you more info.


Regards

Hi again, it seems to be related to the subformat option. With the default
option seems to work fine.

I think StreamOptimized is mantatory for 'ova' files.

Thanks

It's a bug. I can reproduce it with my 21G guest image. I'll take a look.

I guess I see the problem now - the data is corrupted due to a wrong cluster
allocation during converting to streamOptimized. I'm testing a patch locally.

However there is another problem with streamOptimized which makes it refused in
exporting to VMware application. See also:
