Hi,

after setting up Qubes R4.1 Alpha on a new laptop I found that my old, restored Windows Qubes would not work anymore with R4.1, the reason being the updated qrexec protocol (from version 2 to 3). During my research on the mailing list I stumbled upon the qwt-crossbuild project by tabit-pro that addresses this and other issues. Unfortunately the software did not compile right out-of-the box. I have made some minor changes and created a github repo with the updated version:

https://github.com/uiskla/qwt-crossbuild

I made essentially the following minor changes:

  * Specified to use Fedora 32 (instead of latest, which is probably 33) for the Docker image build
  * Removed some conflicting packages in the Dockerfile
  * Added a patch to remove header annotations not understood by mingw and added that to the SPEC file

With these change I have successfully built a .msi installer and tested that with Windows 7 VMs and DVMs. GUI, qrexec, seamless mode etc. seem to work fine. I have sent a pull request to tabit-pro but have not received an answer yet (probably because of the holiday season).

If you want to rebuild, here are some hints:

  * I have cloned the standard Fedora 32 template for devel VM
  * I have followed the steps to install Docker from the Fedora documentation   * The devel VM must be converted to HVM so that it is possible to re-enable cgroup v1 for the kernel (needed by Docker on Fedora)
  * Then follow the steps from the Readme.md in the repo

Kind regards

Peter

Hi,

You should have a look to https://qubes-os.discourse.group/t/testing-windows-and-qwt-in-r4-1/1143/37. Especially this comment https://qubes-os.discourse.group/t/testing-windows-and-qwt-in-r4-1/1143/29?u=fepitre. I've discussed yesterday with @easydozen, we will focus our efforts on Qubes components which will at the end result in the same "tool" when we build the final RPM for QWT.

Best,
Frédéric


Hi,

thanks for the pointer, I missed that thread. Actually I have solved the compilation problems independently in a slightly different manner. I have also not encountered any of the seamless mode problems with Windows 7 - I just tested it again, it works perfectly with Windows 7 DVMs (eg. opening Word attachments from Thunderbird in a DVM). I have created the Windows 7 template VM with the excellent qvm-create-windows-qube.sh script using the ISO from my build process to automatically install QWT (note: slight change to the windows mgmt VM necessary, a script needs to be changed to use the .msi from the crossbuild process instead of an .exe).

I know that the QWT tools need to be adapted to Windows 10 (especially the video driver) and that USB is missing from qwt-crossbuild, but don't really have expertise here. I just wanted to help others like me who want use Windows (D)VMs with Qubes R4.1. I plan to test it with a Windows 10 automated installation using the qvm-create-windows-qube.sh script again in the next weeks.

Kind regards

Peter
