Reproduce this on build libvirt-2.0.0-2.el7.x86_64 Verify this BZ on build libvirt-2.0.0-4.el7.x86_64. 1. Use the default auto_dump_path value, there is core dump file generated in directory /var/lib/libvirt/qemu/dump: # ll /var/lib/libvirt/qemu/dump/5-rhel7.2-2016-08-08-18:31:44 -rw-------. 1 root root 1182815304 8月 8 18:31 /var/lib/libvirt/qemu/dump/5-rhel7.2-2016-08-08-18:31:44 2. Set auto_dump_path = "/var/lib/libvirt/qemu/dump1" in qemu.conf and restart libvirtd, core dump file can also be generated: # ll /var/lib/libvirt/qemu/dump1/6-rhel7.2-2016-08-08-18\:42\:30 -rw-------. 1 root root 1182815304 8月 8 18:42 /var/lib/libvirt/qemu/dump1/6-rhel7.2-2016-08-08-18:42:30 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: auto_dump_path setting in the qemu.conf does not work, the auto-dump file will be created in the '/' directory. Version-Release number of selected component (if applicable): libvirt-2.0.0-2.el7.x86_64 qemu-kvm-rhev-2.6.0-12.el7.x86_64 How reproducible: 100% Steps to Reproduce: 1.Check the default setting of the auto_dump_path: #cat /etc/libvirt/qemu.conf ... # When a domain is configured to be auto-dumped when libvirtd receives a # watchdog event from qemu guest, libvirtd will save dump files in directory # specified by auto_dump_path. Default value is /var/lib/libvirt/qemu/dump # #auto_dump_path = "/var/lib/libvirt/qemu/dump" ... 2.Start a guest with watchdog device: #virsh dumpxml rhel7.3 ... <watchdog model='i6300esb' action='dump'> <alias name='watchdog0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x0c' function='0x0'/> </watchdog> ... 3.In guest: echo 1 > /dev/watchdog Actual results: The auto dump file created in the '/' directory: Expected results: The auto dump file created in the default auto_dump_path: /var/lib/libvirt/qemu/dump Additional info: The dump filename is only consists of 'domainid-domainname', so the dump filename is the same for the same guest, it means the dumpfile will be overlapped by the next dump.
