Launching a VM whose config contains a SLIC table, fails with
qemu-kvm-6.2.0-44.1.x86_64:

# virsh start windows10_FUJITSU_lifebook
error: Failed to start domain 'windows10_FUJITSU_lifebook'
error: Interner Fehler: qemu unexpectedly closed the monitor: qxl_send_events:

...
    <acpi>
      <table type='slic'>/usr/share/qemu/SLIC_LIFEBOOK_E756.bin</table>
    </acpi>
...

when removing those lines, VM launching is again possible.
