Hi there.
Since I'm using 3 VM's on a Proxmox I'm trying to use more than just one "vmbr'ed" ethernet device for network traffic.

DELL R710 has 4x1 gigabit NICs. However PROXMOX shows them in a same PCIE group. So far forcing passthrough is a fail.

# lspci | grep Ethernet
01:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
01:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.0 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Limited NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

Any ideas on successful PCIE passthrough ?
I get the "vfio: failed to set iommu for container: Operation not permitted" and fail vm startup while trying any pcie passthrough (even with passthrough entire group).

On the other hand... bonding NICs into one interface might also do the job (at least for now).
I'm thinking of using 1st Broadcom as a Proxmox management and other 3 for bond/stack and use it for VM's.
BTW: The network has single router/gateway with DHCP on it.
It apears I can't define same gateway on more than 1 PM Host interface. If so - how can I allow internet access to both eno1 (Proxmox host) and bond0 interface?
So far I have:
eno1 = static IP proxmox host ethernet interface
bond0 = bond interface with eno2, eno3 and eno4
vmbr0 = static IP bridge with bond0 attached

It seems even if my VMs have DHCP enabled and VM get IP from DHCP server I have no internet connection (just LAN available/browseable). I've tested connections on Win2016 VM. With network diagnostics I get the info: default gateway is inaccessible (or something), while successfully pinging lan devices. Funny thing is... when loop a ping to lets say 8.8.8.8 I sometimes get some packet responds.

/etc/network/interfaces:
auto lo
iface lo inet loopback

auto eno1
iface eno1 inet static
address 192.168.1.193
netmask 255.255.255.0

auto eno2
iface eno2 inet manual

auto eno3
iface eno3 inet manual

auto eno4
iface eno4 inet manual

auto bond0
iface bond0 inet manual
slaves eno2 eno3 eno4
bond_miimon 100
bond_mode balance-rr

auto vmbr0
iface vmbr0 inet static
address 192.168.1.192
netmask 255.255.255.0
gateway 192.168.1.252
bridge_ports bond0
bridge_stp off
bridge_fd 0

So even with network settings shown above I'm (usually) unable to get any internet on vm's (no matter DHCP or static IP setup on vm's. I'm able to ping lan but no response on router/gateway ping).

you must check if the iommu groups are ok and you can pass them through.

see https://pve.proxmox.com/wiki/Pci_passthrough#Verify_IOMMU_isolation

This sounds like a routing problem outside PVE.
In you, configuration PVE do not touch the network traffic form the VM.
The gateway of vmbr is only for the PVE itself.

OK, I've made some progress setting up network.
ENO1 is my main Proxmox interface now (with manual IP/netmask/gateway set).
Next I've created 3 vmbrs (with single eno on each, IP/netmask/gateway blank), then attached each vmbr to single VM. Not sure if it's an optimal setup but seems to work. Gave up with link aggregation setup though...

Now, my iommus:

My CPUs are: 2x Intel Xeon X5670 - those should fully support passthrough setup.

You can only use the hole iommu group and not a single menber of the group.
If the dev is not isolated in an iommu group your CPU can support iommu but it is nothing worth.
The iommu goups are created by the Mainbord vendor (bios and HW layout).

The output you have send is not useful.
Pleas use this script to get a sorted and meaningfull output.

Code: 
#!/bin/bash
shopt -s nullglob
for d in /sys/kernel/iommu_groups/*/devices/*; do
    n=${d#*/iommu_groups/*}; n=${n%%/*}
    printf 'IOMMU Group %s ' "$n"
    lspci -nns "${d##*/}"
done;

BTW: If I set multiple VM's sharing same virtual bridge (and all VM's are in same network) what speed transfer can I get between them? Network adapers are set as VirtIO model, virtual network adapters under VMs show 10Gbps speed. So, is network traffic (inside host itself) relying on physical network limitations (lets say LAN infrastructure is only 100Mbps or 1000Mbps)?
