I cloned git://git.kernel.org/pub/scm/virt/kvm/kvm.git 73917739334c6509 commit, but this is breaking my system... Slim is not able to start i3, xdm is not killing X when I stop xdm, qemu is not able to start when I don't use option -nographic log from qemu on that kernel version: xcb_connection_has_error() returned true No protocol specified Could not initialize SDL(No available video device) - exiting On main kernel branch I don't have those problems. I tried to run with -nographic, and tried pc-i440fx-2.1 but the same problem as before, high cpu usage and no graphic on my GPU. I don't know if that will help by this is my log from option -global isa-debugcon.iobase=0x402 -debugcon file:fedora.ovmf.log: https://bpaste.net/show/36c54dba68c2
