Network settings of virtual machines

You can add, remove, and edit the VM's network interface settings. The list of available interfaces depends on the network setting on the cluster node.

To manage network settings, go to Virtual machines → select a VM → Parameters button → Network Settings tab.

Add the network interface

To add a network interface:

1. Click the Add interface button.
2. Specify the interface settings:
   1. Choose a Network type:
      
      • Main;
      • Additional;

      • Virtual. 

        For more information about network types, see the articles Main and additional network, Virtual networks (VxLAN).
   2. Specify the MAC address. If the value is blank, the platform will generate the MAC address automatically.

   3. For the main or secondary network, in the Connect to bridge field, select the bridge to which the interface will be connected. 

      Each bridge can only be used in one interface.
   4. Choose a Network device type — virtual NIC model:
      
      • virtio;
      • e1000;
      • e1000e;

      • rtl8139. 

        For the VM to work correctly with the selected device type, drivers for the device must be installed in the guest OS. 

        If the OS was installed from an ISO image, it is recommended to select e1000. In other cases it is recommended to choose virtio. 

   5. To not assign an IP address to an interface on the main or secondary network, enable the Create an interface without an IP address option.
   6. To assign one or more IP addresses to the interface:
      
      • for the main or secondary network — select the assignment method:
        
        • From pool IPv4 or From pool IPv6:
          1. Choose an IP address pool.
          2. Specify the Number of IP addresses.
        • Manually — specify the IPv4 address or IPv6 subnet;
        • Via DHCP;
      • for the virtual network:
        1. Choose an Virtual network.
        2. Choose a Local network.
        3. Specify the Number of IP addresses.
3. Click the Create button.

Edit the network interface

Changing the bridge

Bridge change is supported only for the main and secondary network interfaces. The operation is performed without rebooting the VM.

To change the bridge:

1. Choose an interface →  menu → Edit interface.
2. Choose the required bridge in the Connect to bridge field.
3. Click the Save button.

Change the type of network device

Changing the network device type may require additional drivers to be installed on the VM. The VM will be rebooted after the change.

To change the device type:

1. Choose an interface →  menu → Edit interface.
2. Choose the required Network device type.
3. Click the Save button.

Changing the IP addresses

When changing IP addresses, the existing IP addresses will be removed from the interface. If you change the network type, the interface will be assigned a bridge corresponding to the selected network.

To change IP addresses:

1. Choose an interfave →  menu → Edit IP address.
2. Choose a Network type:
   
   • Main;
   • Additional;
   • Virtual. 
3. To not assign an IP address to an interface on the main or secondary network, enable the Create an interface without an IP address option.
4. To assign one or more IP addresses to the interface:
   
   • for the main or secondary network — select the assignment method:
     
     • From pool IPv4 or From pool IPv6:
       1. Choose an IP address pool.
       2. Specify the Number of IP addresses.
     • Manually — specify the IPv4 address or IPv6 subnet;
     • Via DHCP;
   • for the virtual network:
     1. Choose an Virtual network.
     2. Choose a Local network.
     3. Specify the Number of IP addresses.
5. Click the Apply button.

Deleting the network interface

To delete an interface, select the interface → menu → Delete Interface.
