Hello Guys

In two nodes with Proxmox 5.1-3 have dedicated to management of proxmox.

My problem is the following.

Each node have 4 interface qlogic 57810 with LAG from server to Juniper.

Understand with openvswitch I can create a bridge and assign the vlan tag so that the VMs can have access.

The problem is that no VM has access to the network and I have reviewed everything and I can not find the error.

This is my configuration in Proxmox.

-------------------------------------------------------------------
auto lo
iface lo inet loopback

iface ens192 inet manual

iface ens256 inet manual

iface ens224 inet manual

allow-vmbr1 bond0
iface bond0 inet manual
ovs_bonds ens224 ens256
ovs_type OVSBond
ovs_bridge vmbr1
ovs_options bond_mode=active-backup

auto vmbr0
iface vmbr0 inet static
address 192.168.0.70
netmask 255.255.255.0
gateway 192.168.0.1
bridge_ports ens192
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet static
address 192.168.1.100
netmask 255.255.255.0
ovs_type OVSBridge
ovs_ports bond0 vlan100 vlan200

allow-vmbr1 vlan100
iface vlan100 inet manual
ovs_type OVSIntPort
ovs_bridge vmbr1
ovs_options tag=100

allow-vmbr1 vlan200
iface vlan200 inet manual
ovs_type OVSIntPort
ovs_bridge vmbr1
ovs_options tag=200

-----------------------------------------------------

Thanks for your help.

My guess is a mismatch between the link aggregation protocol/mode used on Proxmox and the switch. Also, assign IP addresses to the interfaces, not the bridge itself.

FWIW, here's my setup below. A basic two NIC LAGG plus a single management interface. VMs/CTs are assigned to a VLAN in their individual configs.

Code: 
auto lo
iface lo inet loopback
iface eno1 inet manual
iface eno2 inet manual

allow-vmbr0 bond0
iface bond0 inet manual
        ovs_bonds eno1 eno2
        ovs_type OVSBond
        ovs_bridge vmbr0
        ovs_options lacp=active bond_mode=balance-slb

auto vmbr0
iface vmbr0 inet manual
        ovs_type OVSBridge
        ovs_ports bond0 vlan99

allow-vmbr0 vlan99
iface vlan99 inet static
        address  192.168.99.10
        netmask  255.255.255.0
        gateway  192.168.99.1
        ovs_type OVSIntPort
        ovs_bridge vmbr0
        ovs_options tag=99
 
Hello

Thanks for your help, Post reboot all communication is lost through the administration network and I must remove the vmbr2 configuration. This problem is being presented to me every time I add the OVS for VM traffic

  • The vmbr0 it must be only for management, not you should not pass VM traffic through that network.
  • The vmbr1 it must be only for cluster communications.
  • The vmbr2 is for VM traffic with their respective vlan tag
This is my configuration now:

iface eno4 inet manual

iface enp8s0f0 inet manual

iface enp8s0f1 inet manual

iface enp7s0f1 inet manual

iface enp7s0f0 inet manual

allow-vmbr2 bond0
iface bond0 inet manual
ovs_bonds enp7s0f0 enp7s0f1
ovs_type OVSBond
ovs_bridge vmbr2
ovs_options bond_mode=balance-slb lacp=active

auto vmbr0
iface vmbr0 inet static
address 172.31.42.40
netmask 255.255.255.0
gateway 172.31.42.1
bridge_ports eno3
bridge_stp off
bridge_fd 0

auto vmbr1
iface vmbr1 inet static
address 172.31.47.40
netmask 255.255.255.0
bridge_ports eno4
bridge_stp off
bridge_fd 0

auto vmbr2
iface vmbr2 inet manual
ovs_type OVSBridge
ovs_ports bond0 vlan13

allow-vmbr2 vlan13
iface vlan13 inet static
address 10.226.1.240
netmask 255.255.255.0
ovs_type OVSIntPort
ovs_bridge vmbr2
ovs_options tag=13


Thanks for your help
