There was a bug reported where qemu command line was giving core dump…

… error as below. ** 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) A fix has been posted upstream and is merged with distros(Fedora and Ubuntu). Adding this test case to catch such a scenario in future. Reference bug: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/2055003 Signed-off-by: Kowshik Jois B S <[email protected]>
