[RHEL 8.6.z][i440fx]Migration failed between two z versions on rhel 8.6.z

Please provide the package NVR for which bug is seen:

src:

kernel-4.18.0-372.94.1.el8_6.x86_64

qemu-kvm-6.2.0-11.module+el8.6.0+20793+2184cc28.11.x86_64

How reproducible:

5/5

It's not reproduced on RHEL 8.10.0 but it can be reproduced between two z stream versions on RHEL 8.6.0. Filing it on RHEL 8.10.0 first.
