What were you trying to do that didn't work?

• When do migration test from RHEL9.4 to RHEL8.10, hit BSOD on Win11 and Win2022 guest.

Please provide the package NVR for which bug is seen:

RHEL9.4.0 Host:

• kernel-5.14.0-417.el9.x86_64
• qemu-kvm-8.2.0-3.el9.x86_64
• edk2-ovmf-20231122-2.el9.noarch

RHEL8.10.0 Host:

• kernel-4.18.0-538.el8.x86_64
• qemu-kvm-6.2.0-46.module+el8.10.0+21144+ad14f781.x86_64
• edk2-ovmf-20220126gitbb1bba3d77-8.el8.noarch

How reproducible:

Steps to reproduce

1. On RHEL9.4 host, boot a windows vm(Win11 or Win2022) up:

3. On both src and dst qmp monitor, execute follows command:
   • $ telnet 10.72.140.74 1232
   • {"execute":"qmp_capabilities"}

     {"execute":"migrate-set-capabilities","arguments":

     Unknown macro: {"capabilities"}

     ]}}   — run this command on both src and dst host

1. On src qmp monitor, do migrate:

   • • Unknown macro: {"execute"}
       }

• • • {"execute":"migrate-start-postcopy"}
    • {"execute":"query-migrate"}

1. Check the dst vm status.  ---> BSOD occurred.
