I thought that it is strange to have such error with such common option, probably something is wrong in my system (it is a mix of stable and testing), but I have no idea for now.. I cannot reproduce this on other machine either :( Any hints to pinpoint this problem are welcome.. Running this through remote ssh I can see what it outputs on quickly opened and closed sdl window - it is the seabios version string. NB I have created a symlink for kvmvapic.bin to get rid of the startup warning. $ ls -lA /usr/share/qemu/kvmvapic.bin lrwxrwxrwx 1 root root 33 Jul 21 10:36 /usr/share/qemu/kvmvapic.bin -> ../seabios/optionrom/kvmvapic.bin Removing this symlink doesn't change anything wrt this bug. > > warning: core file may not match specified executable file. > > Are you sure you're this is not the problem?
