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
