PCI Passthrough: Capabilities: <access denied>

[aplsms]

Hello all,

i have a problem with PCI Passthrough "Cavium QLogic 425/825/42B/82B 4Gbps/8Gbps PCIe dual port FC HBA" to VM.
i follow the https://www.google.com/url?sa=t&sou...n.com/en/wiki/Enable_Proxmox_PCIe_Passthrough

And i have on the hosts side:

i able to get link status on the host side:

root@proxmox:~# cat /sys/class/fc_host/host*/port_state
Online
Linkdown

but there is nothing on the guest side:
