since I upgrade kqemu to 1.4, my system reboots when I uses qemu with kqemu enabled. Reproducible: Always Steps to Reproduce: 1.modprobe kqemu 2.launch qemu with -enable-kqemu Actual Results: then I get new window, in which guest OS is booting normally. but 1 seccond later, display blackouts suddenly. and system reboots. Expected Results: at least, kernel survive. my Xorg server uses nvidia-driver, so nvidia module is loaded on my kernel in usual. but unloading nvidia module and using nv driver results same. I uses gentoo-source for kernel. I know kqemu is no longer supported by upstream. but my system has no kvm. and I think it is a wonder running qemu-machine in qemu-machine in qemu-machine in ... recursively with less speed down.

You don't say which version of qemu you were using, but qemu-0.11.1 really does need kqemu-1.4.0_pre1 due to a change in the API for the KQEMU_EXEC ioctl (the layout of the struct kqemu_cpu_state type changed). qemu-0.14.0 does not support kqemu at all!
kqemu is masked for removal so this will not be fixed.
