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.
