Hello,

I've setup a Linux Bond + Bridge according to the following config:


Bash:
auto lo
iface lo inet loopback

auto enp8s0f1
iface enp8s0f1 inet static
        address 192.168.100.10/24
        gateway 192.168.100.1
        mtu 9000

auto eno1
iface eno1 inet static
        address 172.16.1.1/29
        mtu 9000

auto enp7s0f0
iface enp7s0f0 inet manual
        mtu 9000

auto enp8s0f0
iface enp8s0f0 inet manual
        mtu 9000

auto enp7s0f1
iface enp7s0f0 inet manual
        mtu 9000

auto bond0
iface bond0 inet manual
        bond-slaves enp7s0f0 enp7s0f1 enp8s0f0
        bond-miimon 100
        bond-mode 802.3ad
        bond-xmit-hash-policy layer2+3
        mtu 9000

auto vmbr0
iface vmbr0 inet manual
        bridge-ports bond0
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094
        mtu 9000

Cluster and host access have dedicated interfaces. Bond0 and vmbr0 is for VM's to use. I've added the new bridge to my VM's and CT's and tagged their interfaces with correct vlan, but get some strange results. The setup is based on router on a stick and the ports on the switch are tagged properly.

I've got a management guest on vlan 11, which should to connect to the guests at vlan 10. The management guest is a VM and it can access all the CT's in vlan 10, but not the VM's. I have tried restarting the host, recreating the VM interface/MAC etc. Nothing works.

The VM's can talk to others on the vlan on the same host, but the traffic from the VM's is not able to leave the host. Again, works flawlessly for CT's.

Any ideas of what to do next?
