Prior to installing the DSC SWe, you have to define the VM's communication interfaces and network configuration on the KVM Host. It is recommended that you create an IP plan before installing the DSC SWe software. You can provide appropriate network connectivity between a VM and your IP network. Record and maintain the IP information for future reference.
The naming of the network devices within the VM depends on the intended function. Each configured VM virtual network device requires its own unique IP address. Additionally, a shared management IP address is provisioned; this shared management IP address migrates from one management device to the other depending on available IP connectivity with the management gateway.
Refer to Configure the VM Environment and KVM Host for additional information on configuring the VM and the physical interfaces on the KVM Host.
To assist you in creating an IP plan, the following table summarizes the network devices within a VM.
VM network device names
VM Virtual Network Device | Intended Function |
---|---|
mgt0 | Management interface for VM 1 |
mgt1 | Management interface for VM 2 |
ha0 | Internal communication between DSC VMs |
pkt0,pkt1,pkt2,pkt3 | Packet interfaces (in any VM). You may use one or more of these interfaces in each VM, depending on your redundancy and throughput requirements. SCTP multi-homing may be used if multiple packet interfaces are configured in a VM. |
imf0, imf1 | Monitoring interface (optional, for use with IMF) |
The following three management IP addresses are required for configuration of the VM management network:
- two IP addresses are required for the VMs (one IP address for each VM)
- one shared IP address is required for both VMs, depending on required network connections
The following table shows an example of IP information needed for the KVM Host.

To configure the IP routing network, typically, one to four IP routing addresses and subnets are assigned to each Routing or Load Balancer VM.
