These are similar to vSwitches on a VMware ESXi host or networks on a XenServer host (in fact networking on a XenServer host is also accomplished using bridges).Ī KVM network bridge is a Layer-2 software device which allows traffic to be forwarded between ports internally on the bridge and the physical network uplinks. The traffic flow is controlled by MAC address tables maintained by the bridge itself, which determine which hosts are connected to which bridge port. The bridges allow for traffic segregation using traditional Layer-2 VLANs as well as SDN Layer-3 overlay networks. On a linux KVM host guest networking is accomplished using network bridges. Installation of the hypervisor and CloudStack agent is pretty well covered in the CloudStack installation guide, so we’ll not spend too much time on this. In this blog post we’re looking at the options for networking KVM hosts using bridges and VLANs, and dive a bit deeper into the configuration for these options. KVM hypervisor networking for CloudStack can sometimes be a challenge, considering KVM doesn’t quite have the same mature guest networking model found in the likes of VMware vSphere and Citrix XenServer. Ubuntu 18.04 has replaced the legacy networking model with the new Netplan implementation, and this does mean different configuration both for linux bridge setups as well as OpenvSwitch. In this revisit of the original blog post we cover new configuration options for CentOS 7.x as well as Ubuntu 18.04, both of which are now supported hypervisor operating systems in CloudStack 4.11. We published the original blog post on KVM networking in 2016 – but in the meantime we have moved on a generation in CentOS and Ubuntu operating systems, and some of the original information is therefore out of date.
