[Qemu-devel] qemu-img: error while reading

[Torstenl]

Hallo ,

I try to convert image vmdk 2 raw.
Is there a possibility to convert this image with qemu-img?
(without vmware-vdiskmanager)

details:

- convert vmdk-image 2 qemu.raw

 ## var
 mount -o loop OSR507V_vmware_1.0.0Di.iso /mnt/tmp
 vmdk=/mnt/tmp/osr507v_VA/osr507v_vmware_1.0.0Di.vmdk
 raw=osr5.raw

- test 1
 $ qemu-img convert -f vmdk $vmdk -O raw $raw
 qemu-img: error while reading

I found some refer to qemu-img in CHANGELOG [1],
thus i test a new version:

- test 5 qemu-0.11
 $ time /tmp/qemu-0.11.0-rc2/qemu-img convert  $vmdk -O raw $raw
 qemu-img: error while reading

 real    0m0.991s
 user    0m0.050s
 sys     0m0.000s

  - file was created, but included "0" only and alloc 0bytes:
  $ ls -l $raw
  -rw-r--r-- 1 molle molle 8589934592 Sep 16 20:14 osr5.raw
  $ du -sk $raw
  0       osr5.raw

  - strace say:
