After a discussion with qemu team even properly generated backtrace doesn't contain enough information about the crash. Also since RHEL 7.4 the generated crash dump doesn't contain guest memory dump, so the size should keep around 500MB. That's why we are going to change abrt configuration again to save complete core dump. # ls -l */*core* -rw-r-----. 1 root abrt 387616768 Mar 7 10:36 ccpp-2018-03-07-10:36:04-5041/coredump # ls -l ccpp-2018-03-07-10\:36\:04-5041/ total 52592 -rw-r-----. 1 root abrt 6 Mar 7 10:36 abrt_version -rw-r-----. 1 root abrt 4 Mar 7 10:36 analyzer -rw-r-----. 1 root abrt 6 Mar 7 10:36 architecture -rw-r-----. 1 root abrt 769 Mar 7 10:36 cgroup -rw-r-----. 1 root abrt 3495 Mar 7 10:36 cmdline -rw-r-----. 1 root abrt 13 Mar 7 10:36 component -rw-r-----. 1 root abrt 7597 Mar 7 10:37 core_backtrace -rw-r-----. 1 root abrt 387616768 Mar 7 10:36 coredump -rw-r-----. 1 root abrt 1 Mar 7 10:37 count -rw-r-----. 1 root abrt 8274 Mar 7 10:37 dso_list -rw-r-----. 1 root abrt 85 Mar 7 10:36 environ -rw-r-----. 1 root abrt 0 Mar 7 10:37 event_log -rw-r-----. 1 root abrt 21 Mar 7 10:36 executable -rw-r-----. 1 root abrt 4 Mar 7 10:36 global_pid -rw-r-----. 1 root abrt 35 Mar 7 10:36 hostname -rw-r-----. 1 root abrt 26 Mar 7 10:36 kernel -rw-r-----. 1 root abrt 10 Mar 7 10:36 last_occurrence -rw-r-----. 1 root abrt 1323 Mar 7 10:36 limits -rw-r-----. 1 root abrt 135 Mar 7 10:37 machineid -rw-r-----. 1 root abrt 61983 Mar 7 10:36 maps -rw-r-----. 1 root abrt 6063 Mar 7 10:36 open_fds -rw-r-----. 1 root abrt 532 Mar 7 10:36 os_info -rw-r-----. 1 root abrt 51 Mar 7 10:36 os_release -rw-r-----. 1 root abrt 27 Mar 7 10:36 package -rw-r-----. 1 root abrt 4 Mar 7 10:36 pid -rw-r-----. 1 root abrt 6 Mar 7 10:36 pkg_arch -rw-r-----. 1 root abrt 2 Mar 7 10:36 pkg_epoch -rw-r-----. 1 root abrt 13 Mar 7 10:36 pkg_name -rw-r-----. 1 root abrt 6 Mar 7 10:36 pkg_release -rw-r-----. 1 root abrt 13 Mar 7 10:36 pkg_vendor -rw-r-----. 1 root abrt 6 Mar 7 10:36 pkg_version -rw-r-----. 1 root abrt 1194 Mar 7 10:36 proc_pid_status -rw-r-----. 1 root abrt 1 Mar 7 10:36 pwd -rw-r-----. 1 root abrt 26 Mar 7 10:36 reason -rw-r-----. 1 root abrt 4 Mar 7 10:36 runlevel -rw-r-----. 1 root abrt 20613548 Mar 7 10:37 sosreport.tar.xz -rw-r-----. 1 root abrt 10 Mar 7 10:36 time -rw-r-----. 1 root abrt 4 Mar 7 10:36 type -rw-r-----. 1 root abrt 3 Mar 7 10:36 uid -rw-r-----. 1 root abrt 5 Mar 7 10:36 username -rw-r-----. 1 root abrt 40 Mar 7 10:37 uuid -rw-r-----. 1 root abrt 2400 Mar 7 10:37 var_log_messages # yum list vdsm Loaded plugins: package_upload, product-id, search-disabled-repos Installed Packages vdsm.x86_64 4.20.19-1.el7ev @rhv-4.2.2 This bugzilla is included in oVirt 4.2.2 release, published on March 28th 2018.

Description of problem: without setting MakeCompatCore=yes (although CreateCoreBacktrace=yes is set) in /etc/abrt/plugins/CCpp.conf the abrt crash report includes the following files: abrt_version cgroup count event_log hostname limits open_fds package pkg_epoch pkg_release proc_pid_status runlevel uid var_log_messages analyzer cmdline dso_list executable kernel machineid os_info pid pkg_fingerprint pkg_vendor pwd time username architecture component environ global_pid last_occurrence maps os_release pkg_arch pkg_name pkg_version reason type uuid with compact core config the output includes also the core_backtrace file with the following output: # cat core_backtrace { "signal": 11 , "executable": "/usr/libexec/qemu-kvm" , "stacktrace": [ { "crash_thread": true , "frames": [ { "address": 140000363764479 , "build_id": "c3f28802314af4ee866bf8d2e1b506b7bbf34cf6" , "build_id_offset": 973567 , "function_name": "ppoll" , "file_name": "/usr/lib64/libc-2.17.so" } , { "address": 93963107712921 , "build_id": "250731da86353c7dda890a58874c5eb9137f95fc" , "build_id_offset": 6033305 , "function_name": "qemu_poll_ns" , "file_name": "/usr/libexec/qemu-kvm" } , { "address": 93963107716520 , "build_id": "250731da86353c7dda890a58874c5eb9137f95fc" , "build_id_offset": 6036904 , "function_name": "main_loop_wait" , "file_name": "/usr/libexec/qemu-kvm" } , { "address": 93963104510348 , "build_id": "250731da86353c7dda890a58874c5eb9137f95fc" , "build_id_offset": 2830732 , "function_name": "main" , "file_name": "/usr/libexec/qemu-kvm" } ] } ] } Version-Release number of selected component (if applicable): vdsm-4-20-12 How reproducible: 100% Steps to Reproduce: 1.kill -SIGSEGV [vm-pid] 2.check /var/tmp/abrt/ output
