What were you trying to do that didn't work?
QE attempted to perform a live virtual machine migration using qemu9 on a system configured with a ConnectX-7 network adapter (MT2910 Family). The migration was expected to be complete without errors, allowing the VM to continue running on the destination host, but hitting error reported.

Please provide the package NVR for which bug is seen:
kernel-core-5.14.0-496.el9.x86_64
qemu-kvm-9.0.0-8.el9.x86_64
libvirt-10.5.0-4.el9.x86_64
virtio-win-prewhql-0.1-262

How reproducible:
100%

Steps to reproduce:
1. The previous steps are as https://issues.redhat.com/browse/RHEL-32200?focusedId=25117728&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-25117728
2. Migrate the VM from the source host to the target host

Expected results:
Migration is successful.

Actual results:
```
virsh migrate wji-win11-24h2 --live --verbose qemu+ssh://hostb.example.com/system
Migration: [100.00 %]error: internal error: QEMU unexpectedly closed the monitor (vm='wji-win11-24h2'): 2024-08-19T02:56:15.951536Z qemu-kvm: get_pci_config_device: Bad config data: i=0x78 read: a0 device: 20 cmask: ff wmask: 0 w1cmask:0

```

Additional Notes:
1. QE also tested the lower qemu-kvm version: qemu-kvm-9.0.0-6.el9.x86_64, which also hit this problem.
2. The source and destination sides use"pci@0000:e1:00.0 enp225s0np0 network MT2910 Family [ConnectX-7]".
