In my case, the service offering has a 2Gbps interface. - The secondary interface ended up with the network offering default, which is a 1Gbps service. <interface type='bridge'> <mac address='06:8b:22:00:00:57'/> <source bridge='breth0-65'/> <target dev='vnet2'/> <model type='virtio'/> <bandwidth> <inbound average='256000' peak='256000'/> <outbound average='256000' peak='256000'/> </bandwidth> <alias name='net0'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <interface type='bridge'> <mac address='02:00:60:ea:00:04'/> <source bridge='breth0-107'/> <target dev='vnet3'/> <model type='virtio'/> <bandwidth> <inbound average='128000' peak='128000'/> <outbound average='128000' peak='128000'/> </bandwidth> <alias name='net1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </interface> Looks to me that your docs (thanks for contributing them) is applicable for KVM too.
