[Qemu-devel] [PATCH v6 00/10] qemu-ga: fsfreeze on Windows using VSS

User-agent: StGit/0.16

Hi,

This is v6 of patch series to add fsfreeze for Windows qemu-guest-agent.

changes from v5:
 - Move VSS requester code into the DLL
   -- Merge patch v5 06/11(add provider) and patch v5 08/11(add requester)
      (-> patch v6 07/10)
   -- Rename qga-provider.dll to qga-vss.dll
   -- Rearrange files in qga/vss-win32* and rename some functions
   -- Introduce ErrorSet structure to call error_set_win32() as callback
      in order to set errors in the DLL without linking glib etc.
 - Make qemu-ga.exe work without qga-vss.dll even though it is configured
   "--with-vss-sdk", although fsfreeze is disabled. (patch 08/10, 09/10)
 - Introduce COMPointer<T> that automates release of COM objects to avoid
   leaks. (patch 07/10)

v5: http://lists.nongnu.org/archive/html/qemu-devel/2013-07/msg00605.html


* Description
  In Windows, VSS (Volume Shadow Copy Service) provides a facility to
  quiesce filesystems and applications before disk snapshots are taken.
  This patch series implements "fsfreeze" command of qemu-ga using VSS.


* How to build & run qemu-ga with VSS support

 - Download Microsoft VSS SDK from:
   http://www.microsoft.com/en-us/download/details.aspx?id=23490

 - Setup the SDK
   scripts/extract-vsssdk-headers setup.exe (on POSIX-systems)

 - Specify installed SDK directory to configure option as:
   ./configure -with-vss-sdk="path/to/VSS SDK" --cross-prefix=i686-w64-mingw32-

 - make qemu-ga.exe qga/vss-win32/qga-vss.{dll,tlb}

 - Install qemu-ga.exe, qga/vss-win32/qga-vss.{dll,tlb}, and
   the other required mingw libraries into the same directory in guests

 - Run `qemu-ga.exe -s install' and `net start qemu-ga' in the guests

Any feedback are appreciated.
