Since version 5.1 (include latest 6.1), QEMU cannot run GCC and some other things with an error `Allocating guest commpage: Operation not permitted`. The problem is NOT reproducible on QEMU 5.0, so probably the problem was caused by a [rework of init_guest_space or the following commits](https://gitlab.com/qemu-project/qemu/-/commit/ee94743034bfb443cf246eda4971bdc15d8ee066) a year ago. + +Also the problem is not reproducible for all users. It is known that it is reproduced on all Arch Linux host machines and some Debian, and probably depends on some kernel build parameters. + +The sysctl `vm.mmap_min_addr` parameter also affects the problem. The error varies depending on its value: +``` +[0 ... 53248] - No error at all +[53249 ... 61440] - Cannot allocate memory +[61441 ... 65536 and higher] - Operation not permitted +``` +Steps to reproduce: +1.
