**qemu-kvm: ../qapi/qobject-output-visitor.c:95: void qobject_output_add_obj(QObjectOutputVisitor *, const char *, QObject *): Assertion `name' failed.
2025-01-25 20:54:29.967+0000: shutting down, reason=crashed**
Steps to reproduce:
1. Could not produce crash with qemu version 9.1.0-7, upgraded to 9.1.0-9.
2. Started VM using cockpit web interface
3. Crashes within 5 seconds of starting
4. Opening a ticket with cockpit-machines tracker as well as this only happens in cockpit-machines. I am able to open console using virt-manager without crashing, it's only with the cockpit-machines web interface on the VM summary page for the specific VM that appears to cause this.
