VMmanager 6: Administrator guide

Initial setup

When you log in to VMmanager for the first time, the initial configuration form will open. It will help you to:

  • create a cluster. A cluster is a set of servers from the same location. Such servers (cluster nodes) allow transferring data between them quickly. You can create virtual machines on these cluster nodes, as well as store disks, disk images, and operating system templates on them. Learn more in Clusters;
  • add the first node (a server) to the cluster;
  • add a network to assign IP addresses to virtual machines. Learn more in Networks

For initial setup:

  1. Edit the cluster creation settings:
    1. Click on Cluster.
    2. Enter a Name of the cluster or Generate a random name automatically.
    3. Select an OS that will become available for installation on virtual machines in the cluster.
    4. Select a Storage type for VM disks. Click on  for extended configuration. 
    5. Enter the Speed limit in Mbit/s. It will be the maximum speed for new and existing virtual machines in the cluster.
    6. Select IP allocation rule: To cluster or To node:
      • To cluster a pool is allocated for the cluster, combining blocks of IP addresses from physical networks;

      • To node — a cluster node is assigned subnet of IP addresses. Virtual machines on this node are allocated only the IP addresses from the specified subnet. This subnet routing type does not allow migrating virtual machines to other cluster nodes. Choose this type, if your cluster is located in the data center Hetzner or OVH.

        For more information please refer to the article Assigning IP addresses to cluster nodes.

    7. Enable the Second network interface option to create a cluster with the main and additional network interface. This will allow you to create several network cards in the VM. Read more in Main and additional network.

  2. Edit the node creation settings:
    1. Click on Node.
    2. Add a Name for your cluster node.


      A server that will be used as a cluster node must meet the requirements described in the article Managing servers in the cluster.

    3. Enter the Public IP address of the node. 
    4. Enter the active SSH-port on the node.
    5. Enter the Root password. 
  3. Edit the network and IP pools creation settings:
    1. Click on Network settings.
    2. Enter the Network in the format <network address>/<network mask prefix>. E.g., "". Learn more in the article Networks, pools, and IP ranges.
    3. Enter the Gateway for the network.
    4. Enter the IP Pool name.
    5. Enter the list of IP for new VM that can be used for the pool. You can enter separate addresses (""), a mask (""), or an IP range ("").


      To create a cluster with two network interfaces, specify the parameters of the main and additional networks separately. 

  4. Click on Apply settings.

You can create and manage virtual machines after this step. Read more in the article Virtual machines.
