Public bug reported: i am unable to run a command line qemu that does not "suck in" the keyboard and mouse of the host PC i tried all that i could from the command line parameters i want to run a headless gui-less kvm host
if i specify a second set of keyboard and mouse with the -usb the only thing that is diffrent is that i have a keyboard and mouse in the VM if i specify the host keyboard and mouse same thing ... the vm is working fine but the host has no control , no keyboard. i dont see any output of anything the only recourse i have is ctrl+alt+delete and that resets the host after 2-3 times. i tried ctrl+alt, ctrl+alt+x , c , z , 2 , etc... also alt + all those combination and alt with F keys no luck. my command line looks like this (altough i tried many other variations) qemu-system-x86_64 -M q35 -enable-kvm \ -cpu host,kvm=off -m 4096 -smp cpu=4,sockets=1,cores=4,treads=1 \ -drive file=xyz.qcow2,if=scsi \ -device vfio-pci, ... (GPU) \ -device vfio-pci, .... (GPU audio) \ -usb -usbdevice host:XXXX:XXXX -usbdevice host:XXXX:XXXX \ <<< same behaviour with and without -vga none -vnc localhost:1 -daemonize i tried with -nographics , -curses, -monitor stdio, pty and none, same result and with -serial as well tried </dev/null at the end of the command no luck same with & my guess is that the keyboard and mouse gets grabbed by the "window" of the qemu regardless if there is graphics or not and i have not foud a "-headless" ,"-nograb" or "-nopussygrab" mode .
