3.4. Managing Network Accounting and Bandwidth

traffic_shaping

If set to yes, traffic limitations for outgoing traffic are set for virtual machines and containers. The default is no.

bandwidth

This parameter lists all network adapters installed on the hardware node and their bandwidth.

totalrate

This parameter defines the bandwidth to allocate for each network class. It is active if traffic shaping is turned on.

rate

If traffic shaping is turned on, this parameter specifies the bandwidth guarantee for virtual machines and containers.

ratebound

If this parameter is set to yes, the bandwidth guarantee (the global rate parameter) is also the limit for the virtual machine or container, and the virtual machine or container cannot borrow the bandwidth from the totalrate bandwidth pool.
