Hi,

If you are worried that a VM overloads the network, you could try to use the 
QoS settings (on the VIF, or on the vswitch port) to limit the data rate 
through that VIF.

Cheers,

Hi Rob,

I have to try this. But i'm not too worried about the network being flooded, it will support it. I'm more concerned about the openvswitch process using 100% cpu and seems to render
the whole host unresponsive to network access.

Also I forgot to mention I was trying this on xapi with debian, so maybe it's not the case
on XCP / XenServer.

Just trying to figure why this is happenning :)

Cheers,
Sébastien
