Accessing NSM GUI

The NSM VM needs to use a bridged network adapter for the GUI to become exposed outside the VM. A bridge interface acts like a virtual switch. It connects your VMs to the physical network, allowing them to communicate as if they were directly plugged into the router/switch.

You'll need administrative privileges (sudo) to modify network interfaces.

If you have a firewall enabled on the host, ensure that the bridge interface is allowed to pass traffic.

To setup a bridged interface for NSM on-prem KVM

  1. Identify the name of your physical network interface which can act as the master interface for the bridge by running:

    ip link show

    Look for the interface that is connected to your network, typically named something like eth0, enp0s3, etc.

  2. Add an up and running interface to the bridge by running 

    sudo ip link set dev <physical_interface> up

    Replace <physical_interface> with the name of your physical interface name.

  3. Create a new bridge interface by running

    sudo ip link add name <bridge_name> type bridge

    Replace bridge_name with your desired bridge name (example br0).

  4. Add your physical network interface to the bridge as master by running

    sudo ip link set <physical_interface> master <bridge_name>

    Replace <physical_interface>, <bridge_name> with the name of your physical network interface, and bridge name respectively.

  5. Bring up the bridge interface by running 

    sudo ip link set dev <bridge_name> up

  6. Assign an IP address to the bridge interface. This can be done using DHCP or a static IP.

    For DHCP:

    sudo dhclient <bridge_name>

    For a static IP:

    sudo ip addr add <ip address/netmask> dev br0

  7. To ensure the bridge configuration persists across reboots, you need to add the configuration to your network configuration files. This may vary based on the network manager used for the KVM host.

  8. Set the NSM VM to use a bridge adapter and via the Device name connect it to the bridge you created on the host.

    From outside the host, you should now be able to access the NSM GUI by browsing to the IP you assigned to the host bridge.

    After successful login, go to NSM Settings and Registration to configure the network settings and register NSM.
