I've now rebuilt Xorg in 64-bit 7.7. With -vga std it works fine. My /usr/bin/qemu is a script, with a lot of options if I want to change some of the values, and it reports what it will run just before it invokes it. On the good runs I am using: qemu-system-x86_64 -enable-kvm -hda LFS7764desk0.img -m 4G -usb -usbdevice tablet -show-cursor -display sdl -cpu kvm64 -monitor stdio -smp 4 -vga std For cirrus and vmware, the final parameter gets changed. I have also added a vga=790 boot option, because the vmware option needed that to give me a framebuffer and I think also requires it to get xorg running with my kernel config. With -vga cirrus, qemu crashed as soon as I selected the normal boot option, and the controlling term's screen showed kvm_set_phys_mem: error registering slot: Cannot allocate memory At that point, free showed 500MB free and 7.4GB available. repeated, using cirrus and vga=790 - booted ok, but crashed in startx and the controlling term was unresponsive. Killed that term, used a new one, confirmed that -vga std still booted. With -vga vmware, selecting vga=790 option the screen blanked as soon as I did that. After a few seconds I closed qemu but the controlling terminal was again unusable. Closed that term, from a new one tried to start with -vga std but I again get kvm_set_phys_mem: error registering slot: Cannot allocate memory and the terminal was unusable. Note that this is not the same message as I got last night, and at the moment free reports 465MB free and 7.4GB available. I'll stop trying to run qemu for the moment. Got to eat, then get back to some AV testing before I do some tags. ĸen -- Nanny Ogg usually went to bed early. After all, she was an old lady.
