Editing Config Files
Use your favorite text editor to make the following changes to:
/etc/libvirt/qemu.conf
Security - uncomment the following line of code and change the value:
security_default_confined = 0
Add these lines to the bottom of the file:
cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc", "/dev/hpet", "/dev/vfio/vfio",
# Your devices go here
]
clear_emulator_capabilities = 0
Inside cgroup_device_acl, add the paths to your keyboard and mouse.
Sample configuration:
cgroup_device_acl = [
"/dev/null", "/dev/full", "/dev/zero",
"/dev/random", "/dev/urandom",
"/dev/ptmx", "/dev/kvm", "/dev/kqemu",
"/dev/rtc","/dev/hpet", "/dev/vfio/vfio",
# Your devices go here
"/dev/input/by-id/usb-30fa_USB_Optical_Mouse-event-mouse",
"/dev/input/by-id/usb-EVGA_Z12_Gaming_Keyboard-event-kbd",
]
clear_emulator_capabilities = 0
Save the file, then restart the libvirtd service.
systemctl restart libvirtd
