> > > I installed Alpine Linux 3.16 virtual machine edition on QEMU/KVM using Virt-Manager. I installed XFCE on it. I wanted to enable copy-and-paste, so I tried to install spice-vdagent on it, but it kept crashing. I checked the output using the "-x" parameter, and basically, it crashed due to the lack of /dev/uinput.

I ran spice-vdagentd with "-x -d -d -f -u /dev/null" and this time, it did not crash. But as soon as I ran "spice-vdagent -x -d", the virtual machine's mouse stopped working. With the debug messages from spice-vdagentd, I knew that the daemon was receiving the mouse pointer movements and button clicks, but somehow the XFCE desktop did not get it, so I could not do things like clicking a window. Keyboard was working, though. Also, probably copy-and-paste also would work, because in the debug message from spice-vdagent, it seemed to have received the event, when I copied some text on the host OS. How can I fix this mouse not moving problem? > > Also, there is another problem. It seems that after running "spice-vdagentd -x -f -u /dev/null", any subsequent execution of it fails with "Fatal could not create the server socket /run/spice-vdagentd/spice-agent-sock: Error binding to address (GUnixSocketAddress): No such file or directory. Rebooting the guest OS did not solve the problem.

If there is anything more I can do, please let me know. If there currently is no way to solve this problem, can't the agent be updated so that it would not crash when /dev/uinput is not present, and continue to do what it can do without /dev/uinput? I mean, all I want is copy-and-paste, and I am not sure why that cannot function without /dev/uinput.
