<div>Hi,</div><div>first of all: I know that a mode when no QXL device is present is "side effect" and maybe is not supported. But I don't see an opportunity to use Nvidia hardware on KVM linux guest other than via spice and spice-streaming-agent.</div><div>So, I try to make it work, but there are troubles with mouse support, screen resizing, and it seems that it is because of spice-vdagent not working. ('connection reset by peer' in spice-vdagent status output)</div><div>No mouse cursor, no mouse buttons reactions.</div><div>Â </div><div>My config:</div><div>- Centos 8</div><div>- nvidia vGPU with proprietary driver is the only video adapter.</div><div>- spice-vdagent v.0.20 and qemu-guest-agent are installed.</div><div>- /run/spice-vdagentd/spice-vdagent-sock is present and has access mode is srw-rw-rw-.</div><div>- QEMU Tablet may be present or not, same effect.</div><div>Â </div><div>What must be interoperability between spice vdagent socket and video driver? Is there an opportunity to use mouse with nvidia non-free driver at all?</div><div>Â </div><div>`systemctl status spice-vdagent.socket` says:</div><div>Â </div><div>```</div><div><div><div>â— spice-vdagentd.socket - Activation socket for spice guest agent daemon</div><div>Â Â Loaded: loaded (/usr/lib/systemd/system/spice-vdagentd.socket; static; vendor preset: disabled)</div><div>Â Â Active: active (running) since Mon 2021-08-23 16:22:43 MSK; 16min ago</div><div>Â Â Listen: /run/spice-vdagentd/spice-vdagent-sock (Stream)</div><div>Â Â Tasks: 0 (limit: 36416)</div><div>Â Â Memory: 0B</div><div>Â Â CGroup: /system.slice/spice-vdagentd.socket</div><div>Â </div><div>Aug 23 16:22:43 localhost.localdomain systemd[1]: Listening on Activation socket for spice guest agent daemon.</div><div>```</div><div>`systemctl status spice-vdagent.service` says: (error "No QXL devices found" appears when virtual video device is set to virtual VGA or cirrus too, but agent is working and mouse, screen resizing Â work as expected)</div><div>Â </div><div>```</div><div><div><div>â— spice-vdagentd.service - Agent daemon for Spice guests</div><div>Â Â Loaded: loaded (/etc/systemd/system/spice-vdagentd.service; indirect; vendor preset: enabled)</div><div>Â Â Active: active (running) since Mon 2021-08-23 16:22:49 MSK; 15min ago</div><div>Â Process: 2100 ExecStart=/usr/sbin/spice-vdagentd $SPICE_VDAGENTD_EXTRA_ARGS (code=exited, status=0/SUCCESS)</div><div>Â Main PID: 2102 (spice-vdagentd)</div><div>Â Â Tasks: 2 (limit: 36416)</div><div>Â Â Memory: 1.3M</div><div>Â Â CGroup: /system.slice/spice-vdagentd.service</div><div>Â Â Â Â Â Â â””â”€2102 /usr/sbin/spice-vdagentd</div><div>Â </div><div>Aug 23 16:22:49 localhost.localdomain systemd[1]: Starting Agent daemon for Spice guests...</div><div>Aug 23 16:22:49 localhost.localdomain systemd[1]: spice-vdagentd.service: Can't open PID file /run/spice-vdagentd/spice-vda></div><div>Aug 23 16:22:49 localhost.localdomain systemd[1]: Started Agent daemon for Spice guests.</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: opening vdagent virtio channel</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: Set max clipboard: 104857600</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: No QXL devices found, not generating xorg.conf</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: Set max clipboard: 104857600</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: No QXL devices found, not generating xorg.conf</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: Error receiving data: Connection reset by peer</div><div>Aug 23 16:22:49 localhost.localdomain spice-vdagentd[2102]: closed vdagent virtio channel</div><div>```</div><div>Â </div><div>Xorg.conf: (I commented out mouse related input in the hope that X server will somehow manage mouse but no luck)</div><div>```</div><div><div><div># nvidia-xconfig: X configuration file generated by nvidia-xconfig</div><div># nvidia-xconfig: Â version 460.73.01</div><div>Â </div><div>Section "ServerLayout"</div><div>Â Â Identifier Â Â "Layout0"</div><div>Â Â Screen Â Â Â 0 Â "Screen0"</div><div># Â Â InputDevice Â Â "Keyboard0" "CoreKeyboard"</div><div># Â Â InputDevice Â Â "Mouse0" "CorePointer"</div><div>EndSection</div><div>Â </div><div>Section "Files"</div><div>EndSection</div><div>Â </div><div># Section "InputDevice"</div><div>Â Â # generated from default</div><div># Â Â Identifier Â Â "Mouse0"</div><div># Â Â Driver Â Â Â Â "mouse"</div><div># Â Â Option Â Â Â Â "Protocol" "auto"</div><div># Â Â Option Â Â Â Â "Device" "/dev/input/mice"</div><div># Â Â Option Â Â Â Â "Emulate3Buttons" "no"</div><div># Â Â Option Â Â Â Â "ZAxisMapping" "4 5"</div><div>#EndSection</div><div>Â </div><div>#Section "InputDevice"</div><div>Â Â # generated from default</div><div># Â Â Identifier Â Â "Keyboard0"</div><div># Â Â Driver Â Â Â Â "kbd"</div><div>#EndSection</div><div>Â </div><div>Section "Monitor"</div><div>Â Â Identifier Â Â "Monitor0"</div><div>Â Â VendorName Â Â "Unknown"</div><div>Â Â ModelName Â Â Â "Unknown"</div><div>Â Â Option Â Â Â Â "DPMS"</div><div>EndSection</div><div>Â </div><div>Section "Device"</div><div>Â Â Identifier Â Â "Device0"</div><div>Â Â Driver Â Â Â Â "nvidia"</div><div>Â Â VendorName Â Â "NVIDIA Corporation"</div><div>Â Â BusID Â Â Â Â Â "PCI:7:0:0"</div><div>EndSection</div><div>Â </div><div>Section "Screen"</div><div>Â Â Identifier Â Â "Screen0"</div><div>Â Â Device Â Â Â Â "Device0"</div><div>Â Â Monitor Â Â Â Â "Monitor0"</div><div>Â Â DefaultDepth Â Â 24</div><div>Â Â SubSection Â Â "Display"</div><div>Â Â Â Â Depth Â Â Â 24</div><div>Â Â EndSubSection</div><div>EndSection</div><div>```</div></div></div></div></div></div></div>
