Hello,
I use the virsh change-media command and since the combination of:
etcsvms5:/kvm/CS8400/M1 # virsh version Compiled against library: libvirt 3.9.0 Using library: libvirt 3.9.0 Using API: QEMU 3.9.0 Running hypervisor: QEMU 2.10.1
etcsvms5:/kvm/CS8400/M1 #
I got the following problem:

journalctl -b | less shows the following:
Nov 14 10:11:32 etcsvms5 kernel: libvirtd[10178]: segfault at 10 ip 00007f49ff969170 sp 00007f4a069cb940 error 4 in libvirt_driver_qemu.so[7f49ff8d9000+172000] Nov 14 10:11:37 etcsvms5 systemd-coredump[42152]: Process 10177 (libvirtd) of user 0 dumped core. Seeing the stack trace of libvirtd will be key to identifying the bug. With any luck systemd-coredump will have captured that. So can you run 'coredumpctl' to get the stack trace it saved.
Then I'd suggest filing a bugzilla ticket against libvirt with the resulting info so we have a record of it.
Regards, Daniel
