I refuse to let SPICE die

Spice VD Agent for Windows Community-maintained Windows guest agent for SPICE. This repository is a public mirror of the abandoned freedesktop.org spice/win32/vd_agent project. Canonical downloads live on GitHub Releases. The agent provides: Client mouse mode without grabbing the pointer Desktop resolution matching the client Clipboard sharing (text and images) File transfer into the guest A Windows service (spice-agent) that starts vdagent.exe in each session Status Red Hat no longer maintains upstream SPICE. This fork keeps the Windows agent building and shipping for current guests, especially Windows 11 VMs on Linux. The tree already includes the multi-GPU mouse fix from d7405ee (vdagent/desktop_layout.cpp): when a real GPU is passed through alongside the SPICE display device, the agent no longer loses mouse movement. License and provenance The agent is GPL-2.0-or-later. See COPYING and the copyright headers in each source file. Original copyright remains with Red Hat, Inc. and other upstream authors. This fork does not claim the Red Hat or SPICE trademarks. Pinned build-time submodules (do not bump casually): Submodule URLs use HTTPS. MSI upgrades keep the historical WiX UpgradeCode (7eb9b146-db04-42d7-a8ba-71fc8ced7eed). Related products are removed after InstallValidate, before the install transaction begins, so the shared components are recopied instead of being deleted by the old package's uninstall. Because wixl does not read the PE version resource, the File table gets RC_FILEVERSION explicitly; keep it identical to the four fields in VS_VERSION_INFO. The x64 installer still only ships vdagent.exe and vdservice.exe into C:\Program Files\SPICE agent\bin. Clone git clone --recursive https://github.com/nefarius/vd_agent.git cd vd_agent If you already cloned without submodules: git submodule update --init --recursive The freedesktop GitLab remote is preserved as upstream after the mirror was created. Fetch it with: git fetch upstream Local build (MSYS2 UCRT64) The Autotools + MinGW-w64 UCRT64 path is the supported way to produce the installer. CMake + MSVC remains available for local development but does not build an MSI. Prerequisites MSYS2 An UCRT64 shell (C:\msys64\ucrt64.exe, or MSYSTEM=UCRT64) From the UCRT64 shell, in the repository root: bash msys2/install.sh autoreconf -i bash msys2/build.sh builducrt64 bash msys2/package.sh builducrt64 install.sh pulls autotools, autoconf-archive, the UCRT64 toolchain, msitools (wixl), and ImageMagick (tests). PNG clipboard conversion uses the Windows Imaging Component that ships with Windows Vista and later. build.sh configures, compiles vdagent.exe / vdservice.exe, and runs test-png, test-log, and test-shell. package.sh then invokes make msi and writes: builducrt64/spice-vdagent-x64- .msi Version strings come from git describe via build-aux/git-version-gen. Release tags must look like v0.11.0 (minor bumps) so Programs and Features shows the tag exactly. Untagged builds add the commit count since the last tag (for example v0.11.0 plus 83 commits becomes 0.11.0.83- ). Configure fails if that count plus --with-buildid reaches 256, because that would collide with the next micro version. To sign a local build, sign the two executables before package.sh, then sign the MSI. Optional MSVC build git submodule update --init --recursive cmake -S . -B build64 -A x64 cmake --build build64 --config Release cmake --build build64 --config Release --target check CI and releases GitHub Actions (.github/workflows/build.yml) builds the x64 UCRT64 MSI on windows-2022. Signing uses SignRelay so the certificate never lands on the runner. The flow matches DsHidMini: Build and test unsigned binaries On a v* tag, sign vdagent.exe and vdservice.exe in place Package the MSI from those binaries Sign the MSI Verify Authenticode (Get-AuthenticodeSignature Status = Valid) Write .sha256 Upload vdagent-win-x64 and, on tags, notify AppVeyorArtifactsReceiver Attach the MSI and checksum to the GitHub Release The SignRelay composite action is pinned to commit 39ccbe0cef16a383237130380a5aef8db040d5d0. The CLI needs .NET 10 on the runner (actions/setup-dotnet with 10.0.x). Repository settings Create these on nefarius/vd_agent (Settings → Secrets and variables): Copy SIGN_RELAY_CI_TOKEN and WEBHOOK_URL from an already-working repo such as DsHidMini. SIGN_RELAY_SERVER is already set as a repository variable. Do not commit secret values. The Windows SignRelay agent holds the code-signing certificate. Configure subject/thumbprint and timestamp there, not in this repository. Publishing a release Update CHANGELOG.md Update CHANGELOG.md Tag an annotated release and push it: git tag -a v0.11.0 -m "vdagent-win 0.11.0" git push origin v0.11.0 Tag an annotated release and push it: git tag -a v0.11.0 -m "vdagent-win 0.11.0" git push origin v0.11.0 Confirm the Build workflow: unsigned path is not used both executables and the MSI verify as Valid artifacts receiver accepted the webhook the GitHub Release contains the MSI and .sha256 Confirm the Build workflow: unsigned path is not used both executables and the MSI verify as Valid artifacts receiver accepted the webhook the GitHub Release contains the MSI and .sha256 Install the MSI in a Windows 11 SPICE guest and run the checklist below Install the MSI in a Windows 11 SPICE guest and run the checklist below If a tagged build fails after signing started, fix the tree and move the tag forward (or use a new minor version). Do not reuse a published MSI name with different bytes. To recover a failed release: delete the GitHub Release draft if any, push a new tag, and keep the previous published tag immutable if users may have downloaded it. appveyor.yml is kept only for historical parity with the last upstream UCRT64 MSI layout. GitHub Actions is the authoritative CI. Remove AppVeyor once a signed Actions MSI has been smoke-tested. Windows 11 VM validation Use a Windows 11 guest on Linux (QEMU/KVM + SPICE), with the QXL or qxl-wddm-dod display device. Clean install — run spice-vdagent-x64-*.msi as Administrator Service — spice-agent is Running / Automatic; vdagent.exe is present in the user session SPICE connection — reconnect virt-viewer / spicy; agent channel is up Clipboard — text and a bitmap both ways File transfer — drop a file from the client; it lands on the desktop Dynamic resolution — resize the client window; the guest desktop follows when the WDDM QXL driver is in use Multi-GPU / passthrough mouse — add a real GPU for passthrough, keep the SPICE display, confirm the pointer keeps moving (the d7405ee fix) Upgrade — install over a previous Spice agent MSI; service comes back Uninstall — remove the product; spice-agent is gone Optional CMake / Fedora notes Fedora cross-builds still work via .gitlab-ci.yml and mingw-spice-vdagent.spec.in; they are not used for GitHub Releases. x86 MSI builds are no longer produced by the maintained pipeline.
