hi all
i am a kvm , qemu user newbie , i am using libvirt and virsh to mange my KVM VMs , i want to limit the network bandwidth of each VM , i come across libvirt xml format option :
<forward mode='nat' dev='eth0'/>
<bandwidth>
<inbound average='1000' peak='5000' burst='5120'/>
<outbound average='128' peak='256' burst='256'/>
</bandwidth>to limit the bandwidth of each vm , however i have a question how does these option applied limit on kvm vm ? through using of linux cgroub or its a qemu network bandwidth limit functionality ?
