Mirror VM-Traffic to VM on same node

[Henrik Gießel]

Dear Ladies and Gentlemen,

we have 1 Proxmox Hosts running to run or development and testing environment. In one of the VMs we are running security tools, that can sniff the network traffic.
Currently it gets the network traffic via Mirror-Ports and we are testing on physical hardware devices and switches.

We want to mirror the traffic of all VMs to the said VM. How can I archive this goal? Creating Mirrorports on physical switches is easy. But I have no idea how I can archive this in Proxmox.

Current Network-Setup:
auto lo
iface lo inet loopback

iface enp3s0f0 inet manual
iface enp3s0f1 inet manual
iface enp4s0f0 inet manual
iface enp4s0f1 inet manual

auto bond0
iface bond0 inet manual
slaves enp3s0f0 enp3s0f1
bond_miimon 100
bond_mode 802.3ad

auto vmbr0
iface vmbr0 inet static
address xxx.xxx.xxx.xxx
netmask yyy.yyy.yyy.0
gateway zzz.zzz.zzz.zzz
bridge_ports bond0
bridge_stp off
bridge_fd 0

All VMs are on vmbr0

Hi,

if you need mirror ports you can do this with OpenVSwitch.
You have to install it manually and also configure mirror ports by yourself.

Thank you for you reply.
I will try it tomorrow and give a feedback.
