[Spice-devel] Windows 10 VDAgent incompatible with "hidden" KVM?
I'm in the process of setting up a Windows 10 (x64) VM with an NVIDIA Quadro P1000 GPU (using PCI passthrough). The GPU will be used only for video processing, so it has no displays connected, and access to the VM's user interface is via RDP or (preferably) SPICE. I have everything working, right up to the point at which I install the SPICE Guest Tools, specifically the guest agent. As soon as the agent is installed, the VM stops responding to any mouse actions; the pointer is still visible, but it has no effect. I am able to connect to the guest with RDP and stop the SPICE VDAgent service. As soon as the service is stopped, the mouse begins working again in the SPICE console (and restarting the agent again causes the mouse to stop working, etc.). This seems to be related to the "hidden KVM" feature that is required by the NVIDIA drivers. Without this flag, the NVIDIA drivers refuse to load in a virtual machine, giving a "Code 43" error. If I remove these lines from my guest's domain XML, I an able to enable the SPICE agent in my Windows 10 guest without breaking my mouse, but of course the NVIDIA GPU doesn't work. Is there any way that this combination can be made to work? -- In Soviet Russia, Google searches you! ___ Spice-devel mailing list Spice-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/spice-devel

The only documentation that I've been able to find is on the libvirt site: https://libvirt.org/formatdomain.html All it says is "hide the hypervisor from standard MSR based discovery." On reflection it's entirely possible that its the NVIDIA drivers them- selves that are breaking things, and the breakage only shows up when the flag is set, because the drivers don't run without the flag. A bit of testing shows that this is the case. As soon as I disable the P1000 in Device Manager, my mouse begins working. In fact, I can re-enable the P1000, and the mouse continues to work. It's acting like it's some sort of ordering issue. And as a further test, stopping and starting the agent while the GPU is enabled causes the mouse to stop working again. It definitely seems that NVIDIA driver "grabs" the mouse if it starts/runs before the agent. Can you post the agent logs when it's not working?

[Spice-devel] How to build Windows vdagent?
Following up on my earlier thread re the agent's incompatibility with "mixed" (QXL + passthrough) configurations.

[Spice-devel] [PATCH] desktop_layout: ignore unconnected video devices
Currently, the Windows agent does not function properly if it detects a
non-QXL video adapter connected to the guest. See:
https://gitlab.freedesktop.org/spice/win32/vd_agent/-/issues/15
https://gitlab.freedesktop.org/spice/win32/vd_agent/-/issues/13
This is true even when the non-QXL adapter does not have any displays
attached, such as when a physical GPU is passed through to the guest for
AI/ML workloads.
With this patch, the agent ignores the presence of unconnected video
outputs and the mouse works as expected. If a display is connected to
a non-QXL adapter, the behavior is unchanged. (Tested on Windows 10 Pro
x64.)

I've tested with multiple QXL displays, which appears to work just fine, including when I disable the first QXL display with the display settings.

[Spice-devel] Windows 7 dual-head - does it work?
After figuring out the syntax required to start a VM with multiple QXL devices, I've been able to get a "dual-head" Windows XP guest working. (This is on a fully updated Fedora 15 system, using spicec.) I have been unable to get this to work with Windows 7 (32-bit). It works fine in single-head mode, but I haven't been able to get the QXL driver to work with the second QXL device. (Device Manager just shows it as a "Video Controller".) I've tried various ways of installing the driver; none of them has worked, and I've experienced a number of blue screens during my attempts. Has anyone got this working? If so, how? Alternatively, if this is known to not work, please tell me, so I can stop wasting my time. ;-) Thanks! -- ======== Ian Pilcher arequip...@gmail.com "If you're going to shift my paradigm ... at least buy me dinner first." ___ Spice-devel mailing list Spice-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/spice-devel

[Spice-devel] Updated Windows QXL driver needed for SPICE 0.8?
I am running Fedora 15 Alpha, which has been updated to SPICE 0.8.0. This appears to cause a "black screen of death" when Windows (7 or XP) loads the QXL driver from qxl-win32-0.6.1.zip. spicec simply shows a black screen, and there's nothing to do but kill the guest. Downgrading the SPICE packages to the 0.7.x versions makes things work. Are there protocol changes in 0.8 that make a new QXL driver necessary?
