Hi, This is v8 of patch series to add fsfreeze for Windows qemu-guest-agent.
changes from v7: - Remove redundant re-assign to $cxx in configure (patch 01/10) - Add comment and cleanup check for ':' used in class definition (patch 03/10) - Fail installation if VSS provider is already installed (patch 07/10) - Disable VSS feature if 32bit agent runs on 64bit Windows (patch 08/10) v7: http://lists.nongnu.org/archive/html/qemu-devel/2013-07/msg02316.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. --- Tomoki Sekiyama (10): configure: Support configuring C++ compiler Add c++ keywords to QAPI helper script checkpatch.pl: Check .cpp files Add a script to extract VSS SDK headers on POSIX system qemu-ga: Add configure options to specify path to Windows/VSS SDK error: Add error_set_win32 and error_setg_win32 qemu-ga: Add Windows VSS provider and requester as DLL qemu-ga: Call Windows VSS requester in fsfreeze command handler qemu-ga: Install Windows VSS provider on `qemu-ga -s install' QMP/qemu-ga-client: Make timeout longer for guest-fsfreeze-freeze command .gitignore | 1 Makefile | 3 Makefile.objs | 2 QMP/qemu-ga-client | 4 configure | 87 +++++++ hmp.c | 2 hw/pci/pci.c | 2 include/qapi/error.h | 13 + qga/Makefile.objs | 5 qga/commands-win32.c | 82 ++++++ qga/main.c | 10 + qga/vss-win32.c | 166 +++++++++++++ qga/vss-win32.h | 27 ++ qga/vss-win32/Makefile.objs | 23 ++ qga/vss-win32/install.cpp | 458 ++++++++++++++++++++++++++++++++++++ qga/vss-win32/provider.cpp | 513 ++++++++++++++++++++++++++++++++++++++++ qga/vss-win32/qga-vss.def | 13 + qga/vss-win32/qga-vss.idl | 20 ++ qga/vss-win32/qga-vss.tlb | Bin qga/vss-win32/requester.cpp | 487 ++++++++++++++++++++++++++++++++++++++ qga/vss-win32/requester.h | 42 +++ qga/vss-win32/vss-common.h | 128 ++++++++++ rules.mak | 9 + scripts/checkpatch.pl | 34 ++- scripts/extract-vsssdk-headers | 35 +++ scripts/qapi.py | 12 + util/error.c | 35 +++ 27 files changed, 2191 insertions(+), 22 deletions(-) create mode 100644 qga/vss-win32.c create mode 100644 qga/vss-win32.h create mode 100644 qga/vss-win32/Makefile.objs create mode 100644 qga/vss-win32/install.cpp create mode 100644 qga/vss-win32/provider.cpp create mode 100644 qga/vss-win32/qga-vss.def create mode 100644 qga/vss-win32/qga-vss.idl create mode 100644 qga/vss-win32/qga-vss.tlb create mode 100644 qga/vss-win32/requester.cpp create mode 100644 qga/vss-win32/requester.h create mode 100644 qga/vss-win32/vss-common.h create mode 100755 scripts/extract-vsssdk-headers
