I got the issue when doing VFIO live migration.
From Destination:
root@btm2:~# qemu-system-x86_64 -device vfio-pci,host=0000:81:00.4,id=mlx5_1 -incoming tcp:10.0.206.112:5900 -m 1G
VNC server running on 127.0.0.1:5900

From source:

root@btm1:~# qm monitor 304
Entering QEMU Monitor for VM 304 - type 'help' for help
qm> migrate -d tcp:10.0.206.112:5900

Anyone can help me on that? Thanks so much
