hi we check
forexample you see Libvirt limit demo is
Code:
<bandwidth>
<inbound average='100' peak='50' burst='1024'/>
<outbound average='100' peak='50' burst='1024'/>
</bandwidth>
so promox kvm how to config in or out bandwith?
please give me guide. tks
 
hi,

you can set bandwidth options in /etc/pve/datacenter.cfg for the whole cluster

check man datacenter.cfg for bwlimit
 
You currently cannot limit ingoing and outgoing traffic with VMs separately, the one provided is for both as this is enough for most cases.

You could use a start hook and add a traffic control qdisk yourself, but this means a bit more hands on work.

Out of interest, for what specific case do you need separate limits?

before we found a vm , we have config bandwith 1Mib1591714886759.png
but this vm still out bandwith 50-100M
so we wish limit net-out, if we vm running virus ,and go out bandwith very big let me upstream swithc port is 1G full.
just this, so you check understand?

If I have 500 Mbps down/50 Mbps up I'd want to only limit upload.
Many providers offer a download "burst" where download could burst to 10 Gbps, but upload is 1 Gbps, no burst, so I could limit download to say 5 Gbps and upload 500 Mbps

OK, limiting upload sounds reasonable and that's the direction which can be actually limited sanely.

Limiting download is the one which makes seldom sense (as once the traffic controller before the tap device is hit the traffic got already on the Linux Bridge and thus was accounted to a host from the outside perspective).

Has this been implemented anywhere, or are network limits via the host still symmetrical?
