I tried add myself to input group. don't work. not test if add root user to input group works but can confirm if change all /dev/input/eventx to 0666 works the keyboard/mouse on the guest i have in the qemu.conf: use r= root group = kvm cgroup_controllers = [ "cpu", "memory", "blkio", "cpuset", "cpuacct" ] and add myself to groups libvirt (created by libvirt) and kvm (created by qemu)
