Description of problem: If mem-path="no exist file", qemu-kvm-rhev will core dump. Version-Release number of selected component (if applicable): How reproducible: 100% Steps to Reproduce: 1./usr/libexec/qemu-kvm -m 1G -object memory-backend-file,host-nodes=0,id=mem-0,policy=bind,prealloc=yes,mem-path=/mnt/kvm_hugepage0,size=1G -numa node,nodeid=0,memdev=mem-0 2. 3. Actual results: /mnt/kvm_hugepage0: No such file or directory Bad ram offset fffffffffffff000 Aborted (core dumped) (gdb) bt #0 0x00007ffff1a075e9 in raise () from /lib64/libc.so.6 #1 0x00007ffff1a08cf8 in abort () from /lib64/libc.so.6 #2 0x0000555555622d0a in qemu_get_ram_block (addr=<optimized out>) at /usr/src/debug/qemu-2.1.2/exec.c:797 #3 0x0000555555624f59 in qemu_get_ram_ptr (addr=18446744073709547520) at /usr/src/debug/qemu-2.1.2/exec.c:1512 #4 0x0000555555658b27 in memory_region_get_ram_ptr (mr=mr@entry=0x555556190940) at /usr/src/debug/qemu-2.1.2/memory.c:1458 #5 0x0000555555761e1c in host_memory_backend_memory_complete (uc=<optimized out>, errp=0x7fffffffe090) at backends/hostmem.c:291 #6 0x00005555557357b5 in object_add (type=<optimized out>, id=0x55555618eb80 "mem-0", qdict=qdict@entry=0x55555618f410, v=0x55555618f310, errp=errp@entry=0x7fffffffe0e8) at qmp.c:630 #7 0x00005555557237a4 in object_create (opts=<optimized out>, opaque=<optimized out>) at vl.c:2899 #8 0x000055555588fd6b in qemu_opts_foreach (list=<optimized out>, func=func@entry=0x555555723600 <object_create>, opaque=opaque@entry=0x0, abort_on_failure=abort_on_failure@entry=0) at util/qemu-option.c:1072 #9 0x000055555561cecc in main (argc=<optimized out>, argv=<optimized out>, envp=<optimized out>) at vl.c:4240 Expected results: qemu-kvm-rhev provide a correctly error message. e.g /mnt/kvm_hugepage0: No such file or directory Additional info:
