Details? Cmdline? Version? Seems like qemu was in no-kvm mode. Was the kvm modules loaded? This is clearly a TCG bug. Closing WONTFIX, because TCG is not supported in RHEL. Bug report suggests the reporter got TCG instead of KVM by accident. That's a common pitfall. Our fix for bug 662701 should help there. |
Description of problem: Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1.start VM by using VirtualBox 2.start VM by using qemu-kvm Actual results: Seg fault happened (gdb) bt #0 tb_alloc_page (tb=0x7f48e56a2010, phys_pc=<value optimized out>, phys_page2=18446744073709551615) at /usr/src/debug/qemu-kvm-0.12.1.2/exec.c:1126 #1 tb_link_phys (tb=0x7f48e56a2010, phys_pc=<value optimized out>, phys_page2=18446744073709551615) at /usr/src/debug/qemu-kvm-0.12.1.2/exec.c:1216 #2 0x00000000004ec4dc in tb_gen_code (env=0x1eafc00, pc=<value optimized out>, cs_base=<value optimized out>, flags=<value optimized out>, cflags=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/exec.c:914 #3 0x00000000004ef2b7 in tb_find_slow (env1=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/cpu-exec.c:168 #4 tb_find_fast (env1=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/cpu-exec.c:189 #5 cpu_x86_exec (env1=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/cpu-exec.c:587 #6 0x000000000040eb06 in qemu_cpu_exec (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/vl.c:4495 #7 tcg_cpu_exec (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/vl.c:4526 #8 main_loop (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/vl.c:4650 ---Type <return> to continue, or q <return> to quit--- #9 main (argc=<value optimized out>, argv=<value optimized out>, envp=<value optimized out>) at /usr/src/debug/qemu-kvm-0.12.1.2/vl.c:6848 Expected results: Additional info:
