Some minutes prior to start "Qemu", I have changed value of "shared memory: shmmax & shmall (On the basis of the Handbook:7.4)" using a command "sysctl(8)"... It has appeared, that if to change values of "shared memory" not through "/etc/sysctl.conf", but by means of a command "sysctl(8)" - it is inevitable, later (not at once) there will be a crash of system. Thus, the "Qemu" did not cause crash - It was simply casual concurrence. Forgive, for the erroneous message. Also forgive for my English. Andrew R.M.
