Is it possible to limit VM PPS (Packets Per Second)?

[merkys777]

Hello,
I am researching for the possibility to add global / or individual PPS limits for each VM.
Perhaps anybody knows a working way?

I am struggling as one of the VM inside the node constantly receives DDoS and it doesn't reach BW limit. However, the amount of packets it receives - crashes the network.
I highly appreciate any suggestions

HI, what kind of packets are being send? Do you have SMURFS filter enabled for the VM Firewall?

You can also set a limit rule, so something like e.g. iptables -A tap100i0-IN -m limit --limit 10/s -j ACCEPT followed by a drop or reject rule (note that this is just an untested example and needs to be adapted to your needs).
