Qemu cmdline core dumped with more(8193 or more) cpus ---Debugger--- A debugger is not configured ---Steps to Reproduce--- ---Problem Description--- Qemu cmdline core dumped with more(8193 or more) cpus ---Debugger--- A debugger is not configured ---Steps to Reproduce--- Qemu cmdline core dumped when more number of CPUs were given. [root@ltcmihawk39 ~]# qemu-system-ppc64 -accel tcg -smp 10,maxcpus=9000 ** ERROR:../tcg/region.c:782:tcg_region_init: assertion failed: (region_size >= 2 * page_size) Bail out! ERROR:../tcg/region.c:782:tcg_region_init: assertion failed: (region_size >= 2 * page_size) Aborted (core dumped) Expected Result: Warning message like "Number of cpus requested exceeds the cpus supported" Actual Result: core dumped Steps to Reproduce: -------------------- 1. Clone the upstream qemu from https://gitlab.com/qemu-project/qemu.git 2. Compile qemu with below steps. cd qemu/ git submodule init git submodule update --recursive ./configure --target-list=ppc64-softmmu --prefix=/usr make make install 3. set maxcpus=8193 or more [root@ltcmihawk39 ~]# qemu-system-ppc64 --version QEMU emulator version 8.0.94 (v8.1.0-rc4) Copyright (c) 2003-2023 Fabrice Bellard and the QEMU Project developers NOTE: This behavior is observed only when qemu is built without disabling the tcg.
