http://bugzilla.suse.com/show_bug.cgi?id=1046678 Bug ID: 1046678 Summary: libguestfs: virt-sysprep: segfault in supermin Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Virtualization:Tools Assignee: virt-bugs@suse.de Reporter: martin.wilck@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- supermin dies while running virt-sysprep. "clonevm" is a shell script I wrote. It creates a VM and runs virt-sysprep to do some final customizations on it. virt-sysprep: error: libguestfs error: /usr/bin/supermin killed by signal 11 (Segmentation fault). To see full error messages you may need to enable debugging. Do: export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 and run the command again. For further information, read: http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs You can also run 'libguestfs-test-tool' and post the *complete* output into a bug report or message to the libguestfs mailing list. If reporting bugs, run virt-sysprep with debugging enabled and include the complete output: virt-sysprep -v -x [...] clonevm: ERROR in virt-sysprep --operations defaults,-udev-persistent-net,-ssh-userdir --quiet --hostname "$newname" -a "$NEWROOT" --script "$TMPD/rename_ifaces" at clonevm:223 apollon:/mnt/vms # coredumpctl gdb /usr/bin/supermin PID: 31186 (supermin) UID: 0 (root) GID: 0 (root) Signal: 11 (SEGV) Timestamp: Thu 2017-06-29 14:52:50 CEST (17min ago) Command Line: /usr/bin/supermin --build --if-newer --lock /var/tmp/.guestfs-0/lock --copy-kernel -f ext2 --host-cpu x86_64 /usr/lib64/guestfs/supermin.d -o /var/tmp/.guestfs-0/appliance.d Executable: /usr/bin/supermin Control Group: /user.slice/user-17326.slice/user@17326.service/gnome-terminal-server.service Unit: user@17326.service User Unit: gnome-terminal-server.service Slice: user-17326.slice Owner UID: 17326 (mwilck) Boot ID: 43ccdab44d4340198c8783756adab716 Machine ID: a0385656b74c9241b77c1bb6577a603b Hostname: apollon.suse.de Storage: /var/lib/systemd/coredump/core.supermin.0.43ccdab44d4340198c8783756adab716.31186.1498740770000000.lz4 Message: Process 31186 (supermin) of user 0 dumped core.
