Hi,

Can anybody point me into some documents for traffic limiting per VM?

Say I want to assign 1TB of traffic to VM and if VM will use that traffic then speed of connection goes down to say 1Mb/s.

Is there a way to do it in Proxmox?

there is no built in way to do this, but you could do the following:

log the traffic with the api from:
"/nodes/<nodename>/lxc/<ctid>/status/current"
(the netout and netin values)

and then script the traffic limiting
see the "rate" parameter of the netX devices

The limiting rate is in both directions, so download and upload gets throttled
