shared folders in Windows with QEMU/KVM ?

    Hello,

    
    I am a senior Linux sysadmin, and I am just discovering QEMU/KVM at
    home, where I am using Virtualbox on Ubuntu 16.04. So far, I must
    say I like it ! Many years ago, Qemu was a pain : it is a miracle,
    the improvement is unbelievable ! My warmest congratulations to
    everybody who has worked so hard !

    
    At work, I am administering VSphere and VMware Workstation.

    
    So far, I am not digging into QEMU/KVM internals, rather discovering
    it as an end-user (just to try and see if I can advertise it at
    work, for my non-IT users)

    
    I imported successfully an Ubuntu 16.04 vm from VB to QEMU/KVM, and
    I can drag-and-drop a file from the host to the VM : amazing !

    
    I imported successfully my Windows 7 guest and my Windows 10 guest
    (some filesystem issues with Windows 7 which I fixed, none with
    Windows 10), installed the spice guest tools in both from here :

    
https://www.spice-space.org/download/windows/spice-guest-tools/spice-guest-tools-latest.exe

    
    and I can resize the display nicely.

    
    I am having an issue with the shared folders, which "do not work" :
    what I did :

    
    - in virt-manager, I enabled the channel org.spice-space.webdav.0

    - in the guest, I installed space-webdavd from here :

    https://www.spice-space.org/download/windows/spice-webdavd/

    
    - I read 

    Spice User Manual

    https://www.spice-space.org/spice-user-manual.html

    
    Now : 

    - from this manual, I do not see where I can find this : "Use the
    remote-viewer "File" → "Preferences" menu
    to enable it"

    - I do not find which command provides the option --spice-share-dir : man -K spice-share-dir does not yield any result,
      whereas man -K spice does; and I guess I installed almost
      every (?) available virt* and qemu* package from the Ubuntu
      repository;

      - in Windows (7 and 10) with an elevated cmd.exe : this bad thing
      happens :

      
    C:\WINDOWS\system32>"c:\Program
        Files\SPICE webdavd\map-drive.bat"

      
      C:\WINDOWS\system32>net use *
        http://localhost:9843/

      System error 67 has occurred.

      
      The network name cannot be found.

      
      C:\WINDOWS\system32>REG ADD
"HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\##localhost@9843#DavWWWRoot"
        /v  "_LabelFromReg" /t REG_SZ /d "Spice client" /f

      The operation completed successfully.

      
    even if the Spice proxy service is running,
      as far as I remember - I even disabled the firewall.

      and in the Event Viewer (7 and 10) I see regular occurrences of :

      
    Faulting application name:
        spice-webdavd.exe, version: 0.0.0.0, time stamp: 0x58e61b16

      Faulting module name: libglib-2.0-0.dll,
        version: 2.50.1.0, time stamp: 0x695f011a

      Exception code: 0xc0000005

      Fault offset: 0x000000000004e5e5

      Faulting process id: 0x75c

      Faulting application start time:
        0x01d2d9ff6cdd440f

      Faulting application path: C:\Program
        Files\SPICE webdavd\bin\spice-webdavd.exe

      Faulting module path: C:\Program
        Files\SPICE webdavd\bin\libglib-2.0-0.dll

      Report Id:
        07337de2-e137-49b3-94be-870db95ed5a9

      Faulting package full name: 

      Faulting package-relative application ID:
      

      Can anybody help ? Is this feature publicly available, or is it
      still in development, or stalled, or dropped ?

      
      Best regards
