<div>Hi phil,</div>
<div><br>
</div>
It is used to generate the rxtx_cap in the network_info cache which is in turn used to generate qos params in xenapi in:

<div>~/os/nova/nova/virt/xenapi/vif.py<br>
<div><br>
</div>
<div>I don't believe it is used in the other drivers at all.</div>

<div>tr3buchet or _cerberus_ might be able to add a bit more detail</div>

Can anyone point me to where the rxtx factor of an instance type is currently used in the code please ?<o:p></o:p></div>

I was thinking about the use case of having instance types which are differentiated by their network bandwidth, and how that could be accommodated in a scheduler filter and passed down to the virt layer for cgroup configuration, and the rxtx factor seems to
be the obvious starting point – but I was struggling to see how its already used.<o:p></o:p></div>
