Hello!
Today my DC said "My ports just made an ethernet loop."
At the moment of happening we saw lots of MACs on your port that normally do not belong to you (see the listing below).
Anyone know what's happening?
The Host server have only one bridge vmbr0

Most likely you have several bridges on your proxmox with VMs added to multiple of them.
At some point some vms just pass the traffic between the bridges and it returns the packets back to our network.Anyone know what's happening?
The Host server have only one bridge vmbr0
Like this
auto lo
iface lo inet loopback
iface eno1 inet manual
auto vmbr0
iface vmbr0 inet static
address 192.168.10.2/24
gateway 192.168.10.1
bridge-ports eno1
bridge-stp off
bridge-fd 0
