2022-03-15qga/vss-win32: check old VSS SDK headersMarc-André Lureau
The VssCoordinator & VssAdmin interfaces have been moved to vsadmin.h in the Windows SDK. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <20220222194008.610377-3-marcandre.lureau@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2022-02-21qga/vss: use standard windows headers locationMarc-André Lureau
Stop using special paths with outdated headers from an old SDK. Instead, use standard include paths. You can still build against the old SDK by running configure with --extra-cxxflags="-isystem /path/to/inc/win2003/" (this also allows to build against MinGW headers, which are currently broken as in 9.0) Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-04-26qga-win: Fix a bug where qemu-ga service is stuck during stop operationSameeh Jubran
After triggering a freeze command without any following thaw command, qemu-ga will not respond to stop operation. This behaviour is wanted on Linux as there is no time limit for a freeze command and we want to prevent quitting in the middle of freeze, on the other hand on Windows the time limit for freeze is 10 seconds, so we should wait for the timeout, thaw the file system and quit.

2016-07-12Clean up header guards that don't match their file nameMarkus Armbruster
Header guard symbols should match their file name to make guard collisions less likely. Offenders found with scripts/clean-header-guards.pl -vn. Cleaned up with scripts/clean-header-guards.pl, followed by some renaming of new guard symbols picked by the script to better ones.

2016-07-12Use #include "..." for our own headers, <...> for othersMarkus Armbruster
Tracked down with an ugly, brittle and probably buggy Perl script. Also move includes converted to <...> up so they get included before ours where that's obviously okay.

2016-02-23all: Clean up includesPeter Maydell
Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes. Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Eric Blake <eblake@redhat.com>
2013-09-09qemu-ga: Add Windows VSS provider and requester as DLLTomoki Sekiyama
Adds VSS provider and requester as a qga-vss.dll, which is loaded by Windows VSS service as well as by qemu-ga. "provider.cpp" implements a basic stub of a software VSS provider. Currently, this module only relays a frozen event from VSS service to the agent, and thaw event from the agent to VSS service, to block VSS process to keep the system frozen while snapshots are taken at the host. To register the provider to the guest system as COM+ application, the type library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl), VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also adds pre-compiled .tlb file in the repository in order to enable cross-compile qemu-ga.exe for Windows with VSS support. "requester.cpp" provides the VSS requester to kick the VSS snapshot process. Qemu-ga.exe works without the DLL, although fsfreeze features are disabled. These functions are only supported in Windows 2003 or later. In older systems, fsfreeze features are disabled. In several versions of Windows which don't support attribute VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error. To solve this fundamentally, we need a framework to handle mount writable snapshot on guests, which is required by VSS auto-recovery feature (cleanup phase after a snapshot is taken).
