Description yalzhang@redhat.com 2022-01-21 13:29:02 UTC 
Description of problem:
Guest can not start with SLIC acpi table

Version-Release number of selected component (if applicable):
qemu-kvm-6.2.0-4.el9.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Try to start vm with below xml:
(the slic.dat file get from bug 1248758#c42)
<os>
   ...
    <acpi>
      <table type='slic'>/tmp/slic.dat</table>
    </acpi>
    ...
  </os>

2. Before qemu 6.2, the vm can start successfully. But now, it fails as:
# virsh start rhel86
error: Failed to start domain 'rhel86'
error: internal error: qemu unexpectedly closed the monitor: **
ERROR:../hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)
Bail out! ERROR:../hw/acpi/aml-build.c:61:build_append_padded_str: assertion failed: (len <= maxlen)

Actual results:
Guest can not start with SLIC acpi table

Expected results:
Guest can start successfully
