Public bug reported:


- on a CIFS mount qemu-img claims not to have permissions to write into a file.
- VMDK sparse file creation succeeds
- VMDK Flat file creation create the flat-file, but fails to write the description-file
- VMDK flat file creation succeeds on native linux mount such as ~/tmp or /tmp
- same effect as root or non-root
- same effect with selinux setenforce 0

a) I would have expected that the monolithic flat would have created only one large file just like sparse, but it seems to create a description file, in addition to the storing file.
b) I am aware that qemu-img may have problem opening very large files on CIFS, however, this file is not very large

I retract comment "a)I would have expected that the monolithic flat
would have created only one large file just like sparse, but it seems to
create a description file, in addition to the storing file."

pdf vmdk_specs-1.pdf "Virtual Disk Format 1.1" (https://www.vmware.com/app/vmdk/?src=vmdk) on page 7, line-34, a note is mentioned that says that is just how it is. 
"A virtual disk described as monolithic and flat consists of two files. One file contains the descriptor. The other file is the extent used to store virtual machine data"

The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting the bug state to "Incomplete" now.

If the bug has already been fixed in the latest upstream version of QEMU,
then please close this ticket as "Fix released".

If it is not fixed yet and you think that this bug report here is still
valid, then you have two options:

1) If you already have an account on gitlab.com, please open a new ticket
for this problem in our new tracker here:

    https://gitlab.com/qemu-project/qemu/-/issues

and then close this ticket here on Launchpad (or let it expire auto-
matically after 60 days). Please mention the URL of this bug ticket on
Launchpad in the new ticket on GitLab.

2) If you don't have an account on gitlab.com and don't intend to get
one, but still would like to keep this ticket opened, then please switch
the state back to "New" within the next 60 days (otherwise it will get
closed as "Expired"). We will then eventually migrate the ticket auto-
matically to the new system (but you won't be the reporter of the bug
in the new system and thus won't get notified on changes anymore).

Thank you and sorry for the inconvenience.

  creation in /tmp works
  # cd /tmp

  On the other-hand creating a sparse file works
  cd /mnt/hshare/some/folder/createvmdk/
  [root@fedora createvmdk]# qemu-img create -f vmdk test2.vmdk 100M -o subformat=monolithicSparse

  [root@fedora createvmdk]#  du -k  /tmp/test2*.*
  12      /tmp/test2.vmdk

  test2.vmdk is a binary file
  inside it, located among garbled ascii characters is an embedded VMDK description
