  Hi all,
  I'm trying to convert a qcow2 image file to the vmdk (on Ubuntu Server 12.04):

  # qemu-img convert -f qcow2 -O vmdk -o Stream spv-2912.qcow2 spv-2912-3.vmdk -o subformat=streamOptimized
  VMDK: can't write to allocated cluster for streamOptimized
  qemu-img: error while writing sector 65: Input/output error

  Same result with any input format. Others subformats work but the
  StreamOptimized is by far the most important one. The only workaround
  I found is to migrate to raw and then to use VBoxManage (VirtualBox).

[Radoslav Gerganov]

With the latest codebase there is no error message but the converted
streamOptimized image is incorrect.  I have a patch for this and will
submit it for review soon.

My patch has landed:
https://github.com/qemu/qemu/commit/3efffc3292d94271a15b1606b4a56adf6c6f04ed

I think we can resolve this bug as fixed.   Just one note for those how
are trying to use streamOptimized images with VMware: you need to patch
the VMDK version because VMware products accept only version 3 for
streamOptimized:

# Set VMDK version 3 for foo.vmdk
$ printf '\x03' | dd conv=notrunc of=foo.vmdk bs=1 seek=$((0x4))

Then I guess this is how qemu-img should create the image in the first
place. After all, compatibility with VMware is the only reason why the
VMDK driver exists.

Radoslav or Fam, can one of you send a patch for this?

[Serge Hallyn]

I'm confused- this is marked as affecting qemu-kvm in precise, but the
preceding patch (c6ac36e) which introduced the bug is not there either.
So I'm going to mark this as not affecting precise unless someone speaks
up to say that we in fact need the whole dependent series.

[Qemu-devel] [Bug 1006655] Re: Can't convert to vmdk with the streamOptimized subformat

[Thiago Martins]

I have tried, many times, to use qemu-img to create StreamOptimized for
VMWare ESXi 6.0 OVAs.

It does NOT work.

After days of research, I replaced qemu-img, by vboxmanage, then, it
worked!

Now, I'm using something this:

--
vboxmanage convertfromraw packer/output-vm.raw packer/output-vm-disk1.vmdk --format vmdk --variant Stream
--

I also had to edit the headers, with dd:

---
dd if=output-vm-disk1.vmdk of=output-vm-disk1.descriptor bs=1 skip=512 count=1024
sed -i -e 's/ide/lsilogic/g' output-vm-disk1.descriptor
dd conv=notrunc,nocreat if=output-vm-disk1.descriptor of=output-disk1.vmdk bs=1 seek=512 count=1024
---

This is the only way to build StreamOptimized VMDKs, for inclusion
inside of OVA, that works on VMWare 6.0.

The qemu-img can not be used.

Here is my full solution to this problem (if the same problem):

https://github.com/tmartinx/svauto/blob/dev/image-factory.sh#L510

I'm just not entirely sure if we're talking about the same problem
here...

Cheers!
Thiago

It looks like my problem is different, since I'm not seeing this:

qemu-img: error while writing sector 65: Input/output error

But maybe, it is a light in the end of the tunnel...
