Description of problem:

After live migrating win2016/win2012r2 guest with failover vf between QL41000 and SFC9220 network cards separately on src and dst hosts, ping will fail in windows guest and the network info of Device manager is src netowrk card info, not the dst network card info.

Version-Release number of selected component (if applicable):

1. rpm -q qemu-kvm
   qemu-kvm-7.0.0-3.el9.x86_64
2. uname -r
   5.14.0-92.el9.x86_64

src host nic info
FastLinQ QL41000 Series 10/25/40/50GbE Controller

dst host nic info:
SFC9220 10/40G Ethernet Controller

How reproducible:

100%

Steps to Reproduce:
1.create vf on both src host and dst host

echo 1 > /sys/bus/pci/devices/0000\:1a\:00.1/sriov_numvfs

2. create failover-vf and failover-bridge network on both src and dst host

1. virsh net-dumpxml failover-bridge
   <network connections='1'>
   <name>failover-bridge</name>
   <uuid>1943a508-b0b7-4274-be5a-6f0143d10f40</uuid>
   <forward mode='bridge'/>
   <bridge name='br0'/>
   </network>

1. virsh net-dumpxml failover-vf
   <network connections='1'>
   <name>failover-vf</name>
   <uuid>4319b666-8f4b-410a-886f-17b6df772224</uuid>
   <forward mode='hostdev' managed='yes'>
   <address type='pci' domain='0x0000' bus='0x1a' slot='0x08' function='0x2'/>
   </forward>
   </network>

3. boot win216/win2012r2 guest with failover vf on src host
<interface type='network'>
<mac address='52:54:00:aa:1c:ef'/>
<source network='failover-bridge'/>
<model type='virtio'/>
<teaming type='persistent'/>
<alias name='ua-test'/>
<address type='pci' domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
</interface>
<interface type='network'>
<mac address='52:54:00:aa:1c:ef'/>
<source network='failover-vf'/>
<teaming type='transient' persistent='ua-test'/>
<address type='pci' domain='0x0000' bus='0x05' slot='0x00' function='0x0'/>
</interface>

4. live migrating the guest
5. after migration, check the network in guest
6. reboot the guest or scan the hardware changes via Device manager in guest

Actual results:
After step5, after migration, ping will fail and network info of vf is
QLogic FastLinQ QL41112-DE 10GbE Adapter(src nic info), not the Solarflare Flareon Ultra 8000 Series 10G Adapter(dst nic info).

After step 6, the guest can't be rebooted, and the scan for hardware changes will not quit. Pls see attachments.

Expected results:
After migration, the network should works well in windows guest.

Additional info:

There is not the issue for RHEL guest.
