This also worked for me with a PCIe x4 NIC on the CPU slot in my ASUS board (both my PCH slots are full). Turned off all ASPM options for PCIe in the BIOS and the log errors went away.

I realize this is an old thread, but I've been tring to run a WLC 9800-CL on Unraid 7 and have been running into the same VLAN/Trunking issues. I couldn't get it to pass tagged traffic to save my life, so I thought if anyone else was trying to accomplish this, here's what I did to get it working. I'm running C9800-CL-universalk9.17.09.06 and downloaded the QCOW file from Cisco's website. I have a separate NIC connected to a trunked port on a cheap TP-Link switch. VLANs 10,20,30,40 are tagged on the switch port. VLAN 10 is where the controller's mgmt IP and the APs will join from. In Unraid Network Settings Bonded = NO Bridged = YES. I did not add any other physical NICs to the bridge. Enable VLANs = NO (I have not yet tried turning this on and creating sub interfaces for additional tagged traffic. IDK if this will break the config or not and I think I'll just put the tagged traffic on another NIC) Protocol = IPv4 Only IP Address = None Unraid VM Created a new VM from the Redhat template Changed or set the following. All other settings remained tempalte default. 2 CPU 6GB RAM Machine Type = Q36 6.0 (I think this was the magic setting) BIOS = SeaBIOS VDisk Location = Manual (Browse to the qcow downloaded from Cisco) Network Source = br1 (could be br0, br2, etc depending on what NIC you use. In my system eth1 = br1). I only need one interface since I'm not configuring a dedicated service port. WLC Console Run through the 0 day wizard, don't configure a service port but generate your certs and you can set your IPs here, even configure your wifi if you choose. I prefer to do very minimal stuff here and setup my interfaces from the cli then move to the web interace for the WiFi setup. Below is a summary of my inital basic config. conf t no logging console aaa new-model aaa authentication login default local aaa authorization exec default local int gi1 switchport mode trunk switchport trunk native vlan 10 switchport trunk allowed vlan 10,20,30,40 switchport nonegotiate negotiation auto no mop enabled no mop sysid exit vlan 10 name Prod vlan 20 name Guest vlan 30 name IoT vlan 40 name Dev int vlan 10 ip address 192.168.0.100 255.255.255.0 no mop enabled no mop sysid ip routing ip route 0.0.0.0 0.0.0.0 192.168.0.1 end wr I hope this helps someone.
