The Proxmox VE SDN allows separation and fine grained control of Virtual Guests networks, using flexible software controlled configurations.
Separation consists of zones, a zone is it’s own virtual separated network area. A VNet is a type of a virtual network connected to a zone. Depending on which type or plugin the zone uses it can behave differently and offer different features, advantages or disadvantages. Normally a VNet shows up as a common Linux bridge with either a VLAN or VXLAN tag, but some can also use layer 3 routing for control. The VNets are deployed locally on each node, after configuration was committed from the cluster-wide datacenter SDN administration interface.
The configuration is done at datacenter (cluster-wide) level, it will be saved
in configuration files located in the shared configuration file system:
/etc/pve/sdn
On the web-interface SDN feature have 3 main sections for the configuration
And some options:
This is the main status panel. Here you can see deployment status of zones on different nodes.
There is an Apply button, to push and reload local configuration on all cluster nodes.
After applying the configuration through the main SDN web-interface panel,
the local network configuration is generated locally on each node in
/etc/network/interfaces.d/sdn
, and with ifupdown2 reloaded.
You can monitor the status of local zones and vnets through the main tree.
