Thanks, applied to qga tree: https://github.com/mdroth/qemu/commits/qga I went ahead with the GetVersionEx() version since it's also used elsewhere in qga code. I needed to fix up the version check to be (major > 6) || (major == 6 && minor >= 2) since that seems to align with what's documented here: https://docs.microsoft.com/en-us/windows/desktop/api/winnt/ns-winnt-_osversioninfoa > --- > qga/commands-win32.c | 11 +++++++++++ > 1 file changed, 11 insertions(+) > > diff --git a/qga/commands-win32.c b/qga/commands-win32.c > index fb91f5d..e688e71 100644 > --- a/qga/commands-win32.c > +++ b/qga/commands-win32.c > @@ -846,6 +846,17 @@ qmp_guest_fstrim(bool has_minimum, int64_t minimum, Error > **errp) > GuestFilesystemTrimResponse *resp; > HANDLE handle; > WCHAR guid[MAX_PATH] = L""; > + OSVERSIONINFO osvi; > + BOOL bIsWindows8orLater; > + > + ZeroMemory(&osvi, sizeof(OSVERSIONINFO)); > + osvi.dwOSVersionInfoSize = sizeof(OSVERSIONINFO); > + GetVersionEx(&osvi); > + bIsWindows8orLater = ((osvi.dwMajorVersion == 6) && (osvi.dwMinorVersion > > > = 2)); > + if (!bIsWindows8orLater) { > + error_setg(errp, "fstrim is only supported for Win8+"); > + return NULL; > + } > > handle = FindFirstVolumeW(guid, ARRAYSIZE(guid)); > if (handle == INVALID_HANDLE_VALUE) { > -- > 2.8.1.185.gdc0db2c > > > On Mon, Jul 16, 2018 at 11:10 PM, Michael Roth <mdr...@linux.vnet.ibm.com> > wrote: > > Quoting Sameeh Jubran (2018-06-24 07:45:40) > > From: Sameeh Jubran <sjub...@redhat.com> > > > > The defrag.exe tool which is used for executing the fstrim command > > on Windows doesn't support retrim for OSes lower than Win8.
